Distributed systems collaborate to achieve collective goals via a system of rules. Rules that affords good hygiene, fault tolerance, effective communication and trusted feedback. These rules form protocols which enable the system to achieve its goals.
Distributed and concurrent systems can be considered a social group that collaborates to achieve collective goals. In order to collaborate a system of rules must be applied, that affords good hygiene, fault tolerance, and effective communication to coordinate, share knowledge, and provide feedback in a polite trusted manner. These rules form a number of protocols which enable the group to act as a system which is greater than the sum of the individual components.
In this talk, we will explore the history of protocols and their application when building distributed systems.
If we were to re-score the last 30 seasons according to the “qualifying” format (using the 2010-2013 scoring system), we would see that in most seasons (18 out of 30), three or more drivers would compete for the championship title in the final race (as opposed to 3 out of 30 with a current championship format).
Moreover, the competition for the Championship would begin anew several times each season. This would make the races even more exciting for fans—and this, in turn, would be a beneficial move for F1 as a sport and business.

Massively scalable ETL in real world applications: the hard wayJ On The Beach
Big Data examples always give the correct answers. However, in the real world, Big Data might be corrupt, contradictory or consist of so many small files it becomes extremely hard to keep track - let alone scale. A solid architecture will help to overcome many of the difficulties.
Floris will talk about a real-world implementation of a massively scalable ETL architecture. Two years ago, at the time of the implementation, Airflow just became part of Apache and still left many features to be desired for. However, requirements from the start were thousands of ETL tasks per day on average, but on occasion, this could become hundreds of thousands. The script-based method that was in place was already not capable to meet the requirements on a day to day basis and needed to be replaced as soon as possible. So this custom framework was rolled out in just 8 weeks of development time.
Traditional Big Data is done on Data you have. You load the data into a repository and perform map reduce or other style calculations on the data. However, certain industries need to perform complex operations on data you might not have. Data you can acquire, Data that can be shared with you, and Data that you can model are all types of data you may not have but may need to integrate instantly into a complex data analysis. Problem is: you may not even know you need this data until deep into the execution stack at runtime. This talk discusses a new functional language paradigm for dealing naturally with data you don’t have and about how to make all data first-class citizens, regardless of whether you have it or you don’t, and we will give a demo of a project written in Scala to deal exactly with this issue.
Acoustic Time Series in Industry 4.0: Improved Reliability and Cyber-Security...J On The Beach
Industry 4.0, aka the "Fourth Industrial Revolution," refers to the computerization of manufacturing. One important aspect of Industry 4.0 is the ability to monitor the health and reliability of a physical manufacturing plant using low-cost IoT sensors. For example, machine learning models can be trained to predict the physical degradation of a manufacturing system as a function of acoustic measurements obtained from strategically placed microphones; however, the same acoustic measurements can be used to reverse engineer proprietary information about the manufacturing process and/or precisely what is being manufactured at the time of recording. Thus, improved reliability and fault tolerance is achieved at the cost of what appears to be an unprecedented new class of security vulnerabilities related to the acoustic side channel.
As a case study, we report a novel acoustic side channel attack against a commercial DNA synthesizer, a commonly used instrument in fields such as synthetic biology. Using a smart phone-quality microphone placed on or in the near vicinity of a DNA synthesizer, we were able to determine with 88.07% accuracy the sequence of DNA being produced; using a database of biologically relevant known-sequences, we increased the accuracy of our model to 100%. An academic or industrial research project may use the synthetic DNA to engineer an organism with desired traits or functions; however, while the organism is still under development, prior to publication, patent, and/or copyright, the research remains vulnerable to academic intellectual property theft and/or industrial espionage. On the other hand, this attack could also be used for benevolent purposes, for example, to determine whether a suspected criminal or terrorist is engineering a harmful pathogen. Thus, it is essential to recognize both the benefits and risks inherent to the cyber-physical systems that will inevitably control Industry 4.0 manufacturing processes and to take steps to mitigate them whenever possible.
Where is the edge in IoT and how much can you do there? Data collection? Analytics? I’ll show you how to build and deploy an embedded IoT edge platform that can do data collection, analytics, dashboarding and much more. All using Open Source.
As IoT deployments move forward, the need to collect, analyze, and respond to data further out on the edge becomes a critical factor in the success – or failure – of any IoT project. Network bandwidth costs may be dropping, and storage is cheaper than ever, but at IoT scale, these costs can still quickly overrun a project’s budget and ultimately doom it to failure.
The more you centralize your data collection and storage, the higher these costs become. Edge data collection and analysis can dramatically lower these costs, plus decrease the time to react to critical sensor data. With most data platforms, it simply isn’t practical, or even possible, to push collection AND analytics to the edge. In this talk I’ll show how I’ve done exactly this with a combination of open source hardware – Pine64 – and open source software – InfluxDB – to build a practical, efficient and scalable data collection and analysis gateway device for IoT deployments. The edge is where the data is, so the edge is where the data collection and analytics needs to be.
Drinking from the firehose, with virtual streams and virtual actorsJ On The Beach
Event Stream Processing is a popular paradigm for building robust and performant systems in many different domains, from IoT to fraud detection to high-frequency trading. Because of the wide range of scenarios and requirements, it is difficult to conceptualize a unified programming model that would be equally applicable to all of them. Another tough challenge is how to build streaming systems with cardinalities of topics ranging from hundreds to billions while delivering good performance and scalability.
In this session, Sergey Bykov will talk about the journey of building Orleans Streams that originated in gaming and monitoring scenarios, and quickly expanded beyond them. He will cover the programming model of virtual streams that emerged as a natural extension of the virtual actor model of Orleans, the architecture of the underlying runtime system, the compromises and hard choices made in the process. Sergey will share the lessons learned from the experience of running the system in production, and future ideas and opportunities that remain to be explored.
Over the last twenty years, there has been a paradigm shift in software development: from meticulously planned release cycles to an experimental way of working in which lead times are becoming shorter and shorter.
How can Java ever keep up with this trend when we have Docker containers that are several hundred megabytes in size, with warm-up times of ten minutes or longer? In this talk, I'll demonstrate how we can use Quarkus so that we can create super small, super fast Java containers! This will give us better possibilities for scaling up and down - which can be a game-changer, especially in a serverless environment. It will also provide the shortest possible lead times, as well as a much better use of cloud performance with the added bonus of lower costs.
If we were to re-score the last 30 seasons according to the “qualifying” format (using the 2010-2013 scoring system), we would see that in most seasons (18 out of 30), three or more drivers would compete for the championship title in the final race (as opposed to 3 out of 30 with a current championship format).

When Cloud Native meets the Financial SectorJ On The Beach
We live in our own bubble of microservices and endlessly horizontal scaling infrastructure, but there is still critical infrastructure that runs the world of financial systems depending on Windows boxes, FTP servers, and single-threaded protocols. This talk is about how to glue these two worlds together, what works for us and what doesn't.
The advancement of technology in the last decade or so has allowed astronomy to see exponential growth in data volumes. ESA's space telescope Euclid will gather high-resolution images of a third of the sky, ~850GB of data downloaded daily for 6 years, by 2032 ground-based telescope LSST will have generated 500PB of data and the radio telescope SKA will be producing more data per second than the entire internet worldwide. This talk will address the questions of what current techniques exist to address big data volumes, how the astronomical community will prepare for this big data wave, and what other challenges lie ahead?
The world is moving from a model where data sits at rest, waiting for people to make requests of it, to where data is constantly moving and streams of data flow to and from devices with or without human interaction. Decisions need to be made based on these streams of data in real-time, models need to be updated, and intelligence needs to be gathered. In this context, our old-fashioned approach of CRUD REST APIs serving CRUD database calls just doesn't cut it. It's time we moved to a stream-centric view of the world.
The TIPPSS Imperative for IoT - Ensuring Trust, Identity, Privacy, Protection...J On The Beach
Our increasingly connected world leveraging the Internet of Things (IoT) creates great value, in connected healthcare, smart cities, and more. The increasing use of IoT also creates great risk. We will discuss the challenges and risks we need to address as developers in TIPPSS - Trust, Identity, Privacy, Protection, Safety, and Security - for devices, systems and solutions we deliver and use. Florence leads IEEE workstreams on clinical IoT and data interoperability with blockchain addressing TIPPSS issues. She is an author of IEEE articles on "Enabling Trust and Security - TIPPSS for IoT" and "Wearables and Medical Interoperability - the Evolving Frontier", "TIPPSS for Smart Cities" in the 2017 book "Creating, Analysing and Sustaining Smarter Cities: A Systems Perspective" , and Editor in Chief for an upcoming book on "Women Securing the Future with TIPPSS for IoT."
Pushing AI to the Client with WebAssembly and BlazorJ On The Beach

Want to run your AI algorithms directly in the browser on the client-side without the need for transpilers or browser plug-ins? Well, now you can with WebAssembly and Blazor. WebAssembly (WASM) is the W3C specification that will be used to provide the next generation of development tools for the web and beyond. Blazor is Microsoft’s experiment that allows ASP.Net developers to create web pages that do much of the scripting work in C# using WASM. Come join us as we learn to write code directly in WebAssembly’s human-readable format. Then, we’ll look at the current state of Blazor and how you can use it, along with WebAssembly to run your tooling client side in the browser.
RAFT protocol is a well-known protocol for consensus in Distributed Systems. Want to learn how consensus is achieved in a system with a large amount of data such as Axon Server’s Event Store? Join this talk to hear about all specifics regarding data replication in highly available Event Store!
Axon is a free and open source Java framework for writing Java applications following DDD, event sourcing, and CQRS principles. While especially useful in a microservices context, Axon provides great value in building structured monoliths that can be broken down into microservices when needed.
Axon Server is a messaging platform specifically built to support distributed Axon applications. One of its key benefits is storing events published by Axon applications. In not so rare cases, the number of these events is over millions, even billions. Availability of Axon Server plays a significant role in the product portfolio. To keep event replication reliable we chose RAFT protocol for consensus implementation of our clustering features.
In short, consensus involves multiple servers agreeing on values. Once they reach a decision on a value, that decision is final. Typical consensus algorithms make progress when any majority of their servers is available; for example, a cluster of 5 servers can continue to operate even if 2 servers fail. If more servers fail, they stop making progress (but will never return an incorrect result).
Join this talk to learn why we chose RAFT; what were our findings during the design, the implementation, and testing phase; and what does it mean to replicate an event store holding billions of events!
The Six Pitfalls of building a Microservices Architecture (and how to avoid t...J On The Beach
Thinking of moving to Microservices? Watch out! That quest is full of traps, social traps. If you are not able to handle it, you may be blocked by meetings, frustration, endless challenges that will make you miss the monolith. In this talk, I share my experience and mistakes, so you can avoid them.
Creating or migrating to a Microservices architecture might easily become a big mess, not only due to technical challenges but mostly because of human factors: it’s a major change in the software culture of a company. In this talk, I’ll share my past experience as the technical lead of an ambitious Microservices-based product, I’ll go through the parts we struggled with, and give you some advice on how to deal with what I call the Six Pitfalls:
The Common Patterns Phobia
The Book Club Cult
The Never-Decoupled Story
The Buzz Words Syndrome
The Agile Trap
The Conway’s Law Hackers
Instead of randomly injecting faults ( i.e. Chaos Monkey), what if we could order our experiments to perform min number of experiments for maximum yield? We present a solution(& results) to the problem of experiment selection using Lineage Driven Fault Injection to reduce the search space of faults.
Lineage Driven Fault Injection (LDFI) is a state of the art technique in chaos engineering experiment selection. LDFI since its inception has used an SAT solver under the hood which presents solutions to the decision problem (which faults to inject) in no particular order. As SRE’s we would like to perform experiments that reveal the bugs that the customers are most likely to hit first. In this talk, we present new improvements to LDFI that orders the experiment suggestions.
In the first the half of the talk we will show LDFI is a technique that can be widely used within an enterprise. We present the motivation for ordering the chaos experiments along with some prioritization we utilized while conducting the experiments. We also highlight how ordering is a general purpose technique that we can use to encode the peculiarities of a heterogeneous microservices architecture. LDFI can work in an enterprise by harnessing the observability infrastructure to model the redundancy of the system.
Next, we present experiments conducted within our organization using ordered LDFI and some preliminary results. We show examples of services where we discovered bugs, and how carefully controlling the order of experiments allowed LDFI to avoid running unnecessary experiments. We also present an example of an application where we declared the service shippable under crash stop model. We also present a comparison with Chaos Monkey and show how LDFI found the known bugs in a given application using orders of magnitude fewer experiments than a random fault injection tool like Chaos Monkey.
Finally, we discuss how we plan to take LDFI forward. We discuss open problems and possible solutions for scalarizing probabilities of failure, latency injection, integration with service mesh technologies like envoy for fine-grained fault injection, fault injection for stateful systems.
Key takeaways: 1) Understand how LDFI can be integrated in the enterprise by harnessing the observability infrastructure. 2) Limitations of LDFI w.r.t unordered solutions and why ordering matters for chaos engineering experiments. 3) Preliminary results of prioritized LDFI and a future direction for the community.
Complexity in systems should be defeated if it is possible to do. But the default nature of our computer systems are complex and servers are doomed to fail. In this talk, we will go through new approaches in modern architectures to design and evaluate new computer systems.
A race of two compilers: GraalVM JIT versus HotSpot JIT C2. Which one offers ...J On The Beach
Do you want to check the efficiency of the new, state of the art, GraalVM JIT Compiler in comparison to the old but mostly used JIT C2? Let’s have a side by side comparison from a performance standpoint on the same source code.
The talk reveals how traditional Just In Time Compiler (e.g. JIT C2) from HotSpot/OpenJDK internally manages runtime optimizations for hot methods in comparison to the new, state of the art, GraalVM JIT Compiler on the same source code, emphasizing all of the internals and strategies used by each Compiler to achieve better performance in most common situations (or code patterns). For each optimization, there is Java source code and corresponding generated assembly code in order to prove what really happens under the hood.
Each test is covered by a dedicated benchmark (JMH), timings and conclusions. Main topics of the agenda: - Scalar replacement - Null Checks - Virtual calls - Lock coarsening - Lock elision - Virtual calls - Scalar replacement - Lambdas - Vectorization (few cases)
The tools used during my research study are JITWatch, Java Measurement Harness, and perf. All test scenarios will be launched against the latest official Java release (e.g. version 11).
Leadership is easy when you're a manager, or an expert in a field, or a conference speaker! In a Kanban organisation, though, we "encourage acts of leadership at every level". In this talk, we look at what it means to be a leader in the uncertain, changing and high-learning environment of software development. We learn about the importance of safety in encouraging others to lead and follow, and how to get that safety using both technical and human practices; the necessity of a clear, compelling vision and provision of information on how we're achieving it; and the need to be able to ask awkward and difficult questions... especially the ones without easy answers.
Machine Learning: The Bare Math Behind LibrariesJ On The Beach
During this presentation, we will answer how much you’ll need to invest in a superhero costume to be as popular as Superman. We will generate a unique logo which will stand against the ever popular Batman and create new superhero teams. We shall achieve it using linear regression and neural networks.
Machine learning is one of the hottest buzzwords in technology today as well as one of the most innovative fields in computer science – yet people use libraries as black boxes without basic knowledge of the field. In this session, we will strip them to bare math, so next time you use a machine learning library, you’ll have a deeper understanding of what lies underneath.
During this session, we will first provide a short history of machine learning and an overview of two basic teaching techniques: supervised and unsupervised learning.
We will start by defining what machine learning is and equip you with an intuition of how it works. We will then explain the gradient descent algorithm with the use of simple linear regression to give you an even deeper understanding of this learning method. Then we will project it to supervised neural networks training.
Within unsupervised learning, you will become familiar with Hebb’s learning and learning with concurrency (winner takes all and winner takes most algorithms). We will use Octave for examples in this session; however, you can use your favourite technology to implement presented ideas.
Our aim is to show the mathematical basics of neural networks for those who want to start using machine learning in their day-to-day work or use it already but find it difficult to understand the underlying processes. After viewing our presentation, you should find it easier to select parameters for your networks and feel more confident in your selection of network type, as well as be encouraged to dive into more complex and powerful deep learning methods.
Getting started with Deep Reinforcement LearningJ On The Beach
Reinforcement Learning is a hot topic in Artificial Intelligence (AI) at the moment with the most prominent example of AlphaGo Zero. It shifted the boundaries of what was believed to be possible with AI. In this talk, we will have a look into Reinforcement Learning and its implementation.
Reinforcement Learning is a class of algorithms which trains an agent to act optimally in an environment. The most prominent example is AlphaGo Zero, where the agent is trained to place tokens on the board of Go in order to win the game. AlphaGo Zero has won against the world champion which was thought to be impossible at that time. This was enabled by combining Reinforcement Learning with Deep Neural Networks and is today known as Deep Reinforcement Learning. This has shifted the frontier of Artificial Intelligence and enabled multiple complex use cases, among them controlling the cooling devices in the server rooms by google. Applying Deep Reinforcement Learning saved them several million in power costs. In this talk, we will understand the basics of Deep Reinforcement Learning and implement a simple example. We will have a look at OpenAIs gym which is the defacto standard for Reinforcement Learning environments. This will enable the audience to implement both an environment and Reinforcement Learning agent on their own.
Toward Predictability and Stability At The Edge Of ChaosJ On The Beach
As we edge towards larger, more complex and decoupled systems, combined with the continual growth of the global information graph, our frontiers of unsolved challenges grow equally as fast. Central challenges for distributed systems include persistence strategies across DCs, zones or regions, network partitions, data optimization, system stability in all phases.
How does leveraging CRDTs and Event Sourcing address several core distributed systems challenges? What are useful strategies and patterns involved in the design, deployment, and running of stateful and stateless applications for the cloud, for example with Kubernetes. Combined with code samples, we will see how Akka Cluster, Multi-DC Persistence, Split Brain, Sharding and Distributed Data can help solve these problems.
Spire is a Scala library for fast, generic, and precise numerics. It allows us to write generic numeric algorithms, provides the ‘number tower’ and offers a lot of utilities you didn’t know you needed.
Numeric programming is a notoriously difficult topic. For number crunching, e.g. solving systems of linear equations, we need raw performance. However, using floating-point numbers may lead to inaccurate results. On top of that, in functional programming, we’d really like to abstract over concrete number types, which is where abstract algebra comes into play. This interplay between abstract and concrete and the fact that everything needs to run on finite hardware is what makes good library support necessary for writing fast & correct programs. Spire is such a library in the Typelevel Scala ecosystem. This talk will be an introduction to Spire, showcasing the ‘number tower’, real-ish numbers and how to obey the law.
Istio Service Mesh & pragmatic microservices architectureJ On The Beach
We have been celebrating 2018 as the Year of the Service Mesh, where an open source effort known as Istio has taken and changed how we design and release our applications.
As we start to go toward cloud-native infrastructure and build our applications out of microservices, we must fully face the drawbacks and challenges to doing so. Some of these challenges include how to consistently monitor and collect statistics, tracing, and another telemetry, how to add resiliency in the face of unexpected failure, how to do powerful feature routing and much more.
Istio and service mesh in general help developers solve this in a non-invasive way.
In this session, we’ll show how you can take advantage of these capabilities in an incremental way. We expect most developers haven’t adequately solved for these issues, so we’ll take it to step by step and build up a strong understanding of Istio, how to get quick wins, and harness its power in your production services architecture.
GraalVM is a high-performance runtime for dynamic, static, and native languages. GraalVM supports Java, Scala, Kotlin, Groovy, and other JVM-based languages. At the same time, it can run the dynamic scripting languages JavaScript including node.js, Ruby, R, and Python. In this session we'll talk about the performance boost you can get from running your code on GraalVM, look at the examples of running typical web-applications with it, enhancing them with code in other languages, creating native images for incredibly fast startup and low memory overhead for your services. GraalVM offers you the opportunity to write the code in the language you want, and run the resulting program really fast.
More and more IT organizations are taking the step to Continuous Delivery instead of thinking in sprints or releases. It’s an important investment, and it opens a world of tangible opportunities. In this talk, we’ll see how the ability to deploy individual features influences the way we work, design applications, and perform as an organisation.
“Serverless” is the hottest ticket in town right now.
But many serverless platforms restrict your choice of language and / or dictate where your code runs.
In this talk, I’ll describe how we can go to the serverless ball with open source and the Fn project in particular.
“Serverless” aims to improve developer productivity by abstracting, underlying infrastructure layers. The servers are still there, but you just can’t see them.
This abstraction allows the developer to focus solely on the functions that deliver value to the business and not on the plumbing.
The economics of serverless are also interesting since you only consume resources when your functions run, rather than having applications running continually waiting to server requests.
Sadly some leading serverless platforms are not open and restrict choice in terms of: - language - deployment
In this talk, I want to show how you can do serverless development with your choice of language, and deployment location.

Leveraging AI for facilitating refugee integrationJ On The Beach
Today's world counts more than 20 million refugees, including over 1 million refugees resettled in Europe as a result of the ongoing Syrian civil war. When fleeing conflicts, refugees risk their lives with the hope of building a better future for themselves. However, upon resettling in a new country, refugees struggle to easily find the opportunities available to them and to filter the ones that are the most relevant to their profile and current context.
In this talk, we explain how AI can be leveraged to connect refugees in real-time and in a customized way to the opportunities that will accelerate the most their integration, bringing them a step forward towards the better future they strive to build for themselves.
OpenFOAM solver for Helmholtz equation, helmholtzFoam / helmholtzBubbleFoamtakuyayamamoto1800

In this solver, the Helmholtz equation can be solved by helmholtzFoam. Also, the Helmholtz equation with uniformly dispersed bubbles can be simulated by helmholtzBubbleFoam.
Globus Compute wth IRI Workflows - GlobusWorld 2024Globus
As part of the DOE Integrated Research Infrastructure (IRI) program, NERSC at Lawrence Berkeley National Lab and ALCF at Argonne National Lab are working closely with General Atomics on accelerating the computing requirements of the DIII-D experiment. As part of the work the team is investigating ways to speedup the time to solution for many different parts of the DIII-D workflow including how they run jobs on HPC systems. One of these routes is looking at Globus Compute as a way to replace the current method for managing tasks and we describe a brief proof of concept showing how Globus Compute could help to schedule jobs and be a tool to connect compute at different facilities.

The world is moving from a model where data sits at rest, waiting for people to make requests of it, to where data is constantly moving and streams of data flow to and from devices with or without human interaction. Decisions need to be made based on these streams of data in real-time, models need to be updated, and intelligence needs to be gathered. In this context, our old-fashioned approach of CRUD REST APIs serving CRUD database calls just doesn't cut it. It's time we moved to a stream-centric view of the world.
The TIPPSS Imperative for IoT - Ensuring Trust, Identity, Privacy, Protection...J On The Beach
Our increasingly connected world leveraging the Internet of Things (IoT) creates great value, in connected healthcare, smart cities, and more. The increasing use of IoT also creates great risk. We will discuss the challenges and risks we need to address as developers in TIPPSS - Trust, Identity, Privacy, Protection, Safety, and Security - for devices, systems and solutions we deliver and use. Florence leads IEEE workstreams on clinical IoT and data interoperability with blockchain addressing TIPPSS issues. She is an author of IEEE articles on "Enabling Trust and Security - TIPPSS for IoT" and "Wearables and Medical Interoperability - the Evolving Frontier", "TIPPSS for Smart Cities" in the 2017 book "Creating, Analysing and Sustaining Smarter Cities: A Systems Perspective" , and Editor in Chief for an upcoming book on "Women Securing the Future with TIPPSS for IoT."

RAFT protocol is a well-known protocol for consensus in Distributed Systems. Want to learn how consensus is achieved in a system with a large amount of data such as Axon Server’s Event Store? Join this talk to hear about all specifics regarding data replication in highly available Event Store!
Axon is a free and open source Java framework for writing Java applications following DDD, event sourcing, and CQRS principles. While especially useful in a microservices context, Axon provides great value in building structured monoliths that can be broken down into microservices when needed.
Axon Server is a messaging platform specifically built to support distributed Axon applications. One of its key benefits is storing events published by Axon applications. In not so rare cases, the number of these events is over millions, even billions. Availability of Axon Server plays a significant role in the product portfolio. To keep event replication reliable we chose RAFT protocol for consensus implementation of our clustering features.
In short, consensus involves multiple servers agreeing on values. Once they reach a decision on a value, that decision is final. Typical consensus algorithms make progress when any majority of their servers is available; for example, a cluster of 5 servers can continue to operate even if 2 servers fail. If more servers fail, they stop making progress (but will never return an incorrect result).
Join this talk to learn why we chose RAFT; what were our findings during the design, the implementation, and testing phase; and what does it mean to replicate an event store holding billions of events!
The Six Pitfalls of building a Microservices Architecture (and how to avoid t...J On The Beach
Thinking of moving to Microservices? Watch out! That quest is full of traps, social traps. If you are not able to handle it, you may be blocked by meetings, frustration, endless challenges that will make you miss the monolith. In this talk, I share my experience and mistakes, so you can avoid them.
Creating or migrating to a Microservices architecture might easily become a big mess, not only due to technical challenges but mostly because of human factors: it’s a major change in the software culture of a company. In this talk, I’ll share my past experience as the technical lead of an ambitious Microservices-based product, I’ll go through the parts we struggled with, and give you some advice on how to deal with what I call the Six Pitfalls:
The Common Patterns Phobia
The Book Club Cult
The Never-Decoupled Story
The Buzz Words Syndrome
The Agile Trap
The Conway’s Law Hackers
Instead of randomly injecting faults ( i.e. Chaos Monkey), what if we could order our experiments to perform min number of experiments for maximum yield? We present a solution(& results) to the problem of experiment selection using Lineage Driven Fault Injection to reduce the search space of faults.
Lineage Driven Fault Injection (LDFI) is a state of the art technique in chaos engineering experiment selection. LDFI since its inception has used an SAT solver under the hood which presents solutions to the decision problem (which faults to inject) in no particular order. As SRE’s we would like to perform experiments that reveal the bugs that the customers are most likely to hit first. In this talk, we present new improvements to LDFI that orders the experiment suggestions.
In the first the half of the talk we will show LDFI is a technique that can be widely used within an enterprise. We present the motivation for ordering the chaos experiments along with some prioritization we utilized while conducting the experiments. We also highlight how ordering is a general purpose technique that we can use to encode the peculiarities of a heterogeneous microservices architecture. LDFI can work in an enterprise by harnessing the observability infrastructure to model the redundancy of the system.
Next, we present experiments conducted within our organization using ordered LDFI and some preliminary results. We show examples of services where we discovered bugs, and how carefully controlling the order of experiments allowed LDFI to avoid running unnecessary experiments. We also present an example of an application where we declared the service shippable under crash stop model. We also present a comparison with Chaos Monkey and show how LDFI found the known bugs in a given application using orders of magnitude fewer experiments than a random fault injection tool like Chaos Monkey.
Finally, we discuss how we plan to take LDFI forward. We discuss open problems and possible solutions for scalarizing probabilities of failure, latency injection, integration with service mesh technologies like envoy for fine-grained fault injection, fault injection for stateful systems.
Key takeaways: 1) Understand how LDFI can be integrated in the enterprise by harnessing the observability infrastructure. 2) Limitations of LDFI w.r.t unordered solutions and why ordering matters for chaos engineering experiments. 3) Preliminary results of prioritized LDFI and a future direction for the community.
Complexity in systems should be defeated if it is possible to do. But the default nature of our computer systems are complex and servers are doomed to fail. In this talk, we will go through new approaches in modern architectures to design and evaluate new computer systems.
A race of two compilers: GraalVM JIT versus HotSpot JIT C2. Which one offers ...J On The Beach
Do you want to check the efficiency of the new, state of the art, GraalVM JIT Compiler in comparison to the old but mostly used JIT C2? Let’s have a side by side comparison from a performance standpoint on the same source code.
The talk reveals how traditional Just In Time Compiler (e.g. JIT C2) from HotSpot/OpenJDK internally manages runtime optimizations for hot methods in comparison to the new, state of the art, GraalVM JIT Compiler on the same source code, emphasizing all of the internals and strategies used by each Compiler to achieve better performance in most common situations (or code patterns). For each optimization, there is Java source code and corresponding generated assembly code in order to prove what really happens under the hood.
Each test is covered by a dedicated benchmark (JMH), timings and conclusions. Main topics of the agenda: - Scalar replacement - Null Checks - Virtual calls - Lock coarsening - Lock elision - Virtual calls - Scalar replacement - Lambdas - Vectorization (few cases)
The tools used during my research study are JITWatch, Java Measurement Harness, and perf. All test scenarios will be launched against the latest official Java release (e.g. version 11).
Leadership is easy when you're a manager, or an expert in a field, or a conference speaker! In a Kanban organisation, though, we "encourage acts of leadership at every level". In this talk, we look at what it means to be a leader in the uncertain, changing and high-learning environment of software development. We learn about the importance of safety in encouraging others to lead and follow, and how to get that safety using both technical and human practices; the necessity of a clear, compelling vision and provision of information on how we're achieving it; and the need to be able to ask awkward and difficult questions... especially the ones without easy answers.
Machine Learning: The Bare Math Behind LibrariesJ On The Beach
During this presentation, we will answer how much you’ll need to invest in a superhero costume to be as popular as Superman. We will generate a unique logo which will stand against the ever popular Batman and create new superhero teams. We shall achieve it using linear regression and neural networks.
Machine learning is one of the hottest buzzwords in technology today as well as one of the most innovative fields in computer science – yet people use libraries as black boxes without basic knowledge of the field. In this session, we will strip them to bare math, so next time you use a machine learning library, you’ll have a deeper understanding of what lies underneath.
During this session, we will first provide a short history of machine learning and an overview of two basic teaching techniques: supervised and unsupervised learning.
We will start by defining what machine learning is and equip you with an intuition of how it works. We will then explain the gradient descent algorithm with the use of simple linear regression to give you an even deeper understanding of this learning method. Then we will project it to supervised neural networks training.
Within unsupervised learning, you will become familiar with Hebb’s learning and learning with concurrency (winner takes all and winner takes most algorithms). We will use Octave for examples in this session; however, you can use your favourite technology to implement presented ideas.
Our aim is to show the mathematical basics of neural networks for those who want to start using machine learning in their day-to-day work or use it already but find it difficult to understand the underlying processes. After viewing our presentation, you should find it easier to select parameters for your networks and feel more confident in your selection of network type, as well as be encouraged to dive into more complex and powerful deep learning methods.
Getting started with Deep Reinforcement LearningJ On The Beach
Reinforcement Learning is a hot topic in Artificial Intelligence (AI) at the moment with the most prominent example of AlphaGo Zero. It shifted the boundaries of what was believed to be possible with AI. In this talk, we will have a look into Reinforcement Learning and its implementation.
Reinforcement Learning is a class of algorithms which trains an agent to act optimally in an environment. The most prominent example is AlphaGo Zero, where the agent is trained to place tokens on the board of Go in order to win the game. AlphaGo Zero has won against the world champion which was thought to be impossible at that time. This was enabled by combining Reinforcement Learning with Deep Neural Networks and is today known as Deep Reinforcement Learning. This has shifted the frontier of Artificial Intelligence and enabled multiple complex use cases, among them controlling the cooling devices in the server rooms by google. Applying Deep Reinforcement Learning saved them several million in power costs. In this talk, we will understand the basics of Deep Reinforcement Learning and implement a simple example. We will have a look at OpenAIs gym which is the defacto standard for Reinforcement Learning environments. This will enable the audience to implement both an environment and Reinforcement Learning agent on their own.
Toward Predictability and Stability At The Edge Of ChaosJ On The Beach
As we edge towards larger, more complex and decoupled systems, combined with the continual growth of the global information graph, our frontiers of unsolved challenges grow equally as fast. Central challenges for distributed systems include persistence strategies across DCs, zones or regions, network partitions, data optimization, system stability in all phases.
How does leveraging CRDTs and Event Sourcing address several core distributed systems challenges? What are useful strategies and patterns involved in the design, deployment, and running of stateful and stateless applications for the cloud, for example with Kubernetes. Combined with code samples, we will see how Akka Cluster, Multi-DC Persistence, Split Brain, Sharding and Distributed Data can help solve these problems.
Spire is a Scala library for fast, generic, and precise numerics. It allows us to write generic numeric algorithms, provides the ‘number tower’ and offers a lot of utilities you didn’t know you needed.
Numeric programming is a notoriously difficult topic. For number crunching, e.g. solving systems of linear equations, we need raw performance. However, using floating-point numbers may lead to inaccurate results. On top of that, in functional programming, we’d really like to abstract over concrete number types, which is where abstract algebra comes into play. This interplay between abstract and concrete and the fact that everything needs to run on finite hardware is what makes good library support necessary for writing fast & correct programs. Spire is such a library in the Typelevel Scala ecosystem. This talk will be an introduction to Spire, showcasing the ‘number tower’, real-ish numbers and how to obey the law.
Istio Service Mesh & pragmatic microservices architectureJ On The Beach
We have been celebrating 2018 as the Year of the Service Mesh, where an open source effort known as Istio has taken and changed how we design and release our applications.
As we start to go toward cloud-native infrastructure and build our applications out of microservices, we must fully face the drawbacks and challenges to doing so. Some of these challenges include how to consistently monitor and collect statistics, tracing, and another telemetry, how to add resiliency in the face of unexpected failure, how to do powerful feature routing and much more.
Istio and service mesh in general help developers solve this in a non-invasive way.
In this session, we’ll show how you can take advantage of these capabilities in an incremental way. We expect most developers haven’t adequately solved for these issues, so we’ll take it to step by step and build up a strong understanding of Istio, how to get quick wins, and harness its power in your production services architecture.
GraalVM is a high-performance runtime for dynamic, static, and native languages. GraalVM supports Java, Scala, Kotlin, Groovy, and other JVM-based languages. At the same time, it can run the dynamic scripting languages JavaScript including node.js, Ruby, R, and Python. In this session we'll talk about the performance boost you can get from running your code on GraalVM, look at the examples of running typical web-applications with it, enhancing them with code in other languages, creating native images for incredibly fast startup and low memory overhead for your services. GraalVM offers you the opportunity to write the code in the language you want, and run the resulting program really fast.
More and more IT organizations are taking the step to Continuous Delivery instead of thinking in sprints or releases. It’s an important investment, and it opens a world of tangible opportunities. In this talk, we’ll see how the ability to deploy individual features influences the way we work, design applications, and perform as an organisation.
“Serverless” is the hottest ticket in town right now.
But many serverless platforms restrict your choice of language and / or dictate where your code runs.
In this talk, I’ll describe how we can go to the serverless ball with open source and the Fn project in particular.
“Serverless” aims to improve developer productivity by abstracting, underlying infrastructure layers. The servers are still there, but you just can’t see them.
This abstraction allows the developer to focus solely on the functions that deliver value to the business and not on the plumbing.
The economics of serverless are also interesting since you only consume resources when your functions run, rather than having applications running continually waiting to server requests.
Sadly some leading serverless platforms are not open and restrict choice in terms of: - language - deployment
In this talk, I want to show how you can do serverless development with your choice of language, and deployment location.

Leveraging AI for facilitating refugee integrationJ On The Beach
Today's world counts more than 20 million refugees, including over 1 million refugees resettled in Europe as a result of the ongoing Syrian civil war. When fleeing conflicts, refugees risk their lives with the hope of building a better future for themselves. However, upon resettling in a new country, refugees struggle to easily find the opportunities available to them and to filter the ones that are the most relevant to their profile and current context.
In this talk, we explain how AI can be leveraged to connect refugees in real-time and in a customized way to the opportunities that will accelerate the most their integration, bringing them a step forward towards the better future they strive to build for themselves.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.
