Björn Rabenstein - About SRE – and how (not) to apply it - Codemotion Berlin ...Codemotion
In short, “SRE is what happens when you ask a software engineer to design an operations team.” Let's dive a bit deeper into what SRE (or “Site Reliability Engineering”) means – and then take a step back. SRE was originally created internally at Google to solve Google's challenges of running Google's production systems at Google scale. How can that even work for you, as you are not Google? It won't! Unless you know how to apply Google's lessons to your possibly very different organization. Following SoundCloud's five-year mission to a reliable site should give you plenty of inspiration.

MERN Stack - A Perfect Stack to Choose in 2022.pptx75waytechnologies
JavaScript has been one of the primary choices of developers worldwide for decades. Whether you want to create everything from scratch or build something on your own using a programming language, JavaScript is always the right pick. With the advancement in this programming language, we all ended up with a tech stack.
A stack is an amalgamation of a number of technologies, frameworks, libraries, or components used to create websites or web apps. A stack can perform multiple operations in different aspects of web or web app development and help you reach your final goal. Whenever the technology stack topic arises, the discussion would sound incomplete without having words on the MERN stack. Right? But what is it? What technologies does this stack include? Is it the right pick for your next project? How can it benefit your project? And there are endless questions whose answers you’re looking for.
So, here we bring you this blog post with the motive to clear your every doubt related to the MERN stack.
This is the slide deck to introduce important topics to developer to build great, high performance Single Page Web Applications.

A pattern language for microservices - June 2021 Chris Richardson
The microservice architecture is growing in popularity. It is an architectural style that structures an application as a set of loosely coupled services that are organized around business capabilities. Its goal is to enable the continuous delivery of large, complex applications. However, the microservice architecture is not a silver bullet and it has some significant drawbacks.
The goal of the microservices pattern language is to enable software developers to apply the microservice architecture effectively. It is a collection of patterns that solve architecture, design, development and operational problems. In this talk, I’ll provide an overview of the microservice architecture and describe the motivations for the pattern language. You will learn about the key patterns in the pattern language.
Similar to JVMCon - Reacting to the future of application architecture (20)
For Java developers, the Just-In-Time (JIT) compiler is key to improved performance. However, in a container world, the performance gains are often negated due to CPU and memory consumption constraints. To help solve this issue, the Eclipse OpenJ9 JVM provides JITServer technology, which separates the JIT compiler from the application. JITServer allows the user to employ much smaller containers enabling a higher density of applications, resulting in cost savings for end-users and/or cloud providers. Because the CPU and memory surges due to JIT compilation are eliminated, the user has a much easier task of provisioning resources for his/her application. Additional advantages include: faster ramp-up time, better control over resources devoted to compilation, increased reliability (JIT compiler bugs no longer crash the application) and amortization of compilation costs across many application instances. We will dig into JITServer technology, showing the challenges of implementation, detailing its strengths and weaknesses and illustrating its performance characteristics. For the cloud audience we will show how it can be deployed in containers, demonstrate its advantages compared to a traditional JIT compilation technique and offer practical recommendations about when to use this technology.
Enabling applications to really thrive (and not just survive) in cloud environments can be challenging. The original 12 factor app methodology helped to lay out some of the key characteristics needed for cloud-native applications... but... as our cloud infrastructure and tooling has progressed, so too have these factors.
In this session we'll dive into the extended and updated 15 factors needed to build cloud native applications that are able to thrive in this environment, and we'll take a look at open source technologies and tools that can help us achieve this.
SwissJUG_Bringing the cloud back down to earth.pptxGrace Jansen
How can we effectively develop for the cloud, when we as developers are coding back down on earth? This is where effective cloud-native developer tools can enable us to either be transported into the cloud or alternatively, to bring the cloud back down to earth. But what tools should we be using for this? In this session, we’ll explore some of the useful OSS tools and technologies that can used by developers to effectively develop, design and test cloud-native Java applications.
Our cloud-native environments are more complex than ever before! So how can we ensure that the applications we’re deploying to them are behaving as we intended them to? This is where effective observability is crucial. It enables us to monitor our applications in real-time and analyse and diagnose their behaviour in the cloud. However, until recently, we were lacking the standardization to ensure our observability solutions were applicable across different platforms and technologies. In this session, we’ll delve into what effective observability really means, exploring open source technologies and specifications, like OpenTelemetry, that can help us to achieve this while ensuring our applications remain flexible and portable.

How does one choose to architect a system that has a Microservice / REST API endpoints? There are many solutions out there. Some are better than others. Should state be held in a server side component, or externally? Generally we are told this is not a good practice for a Cloud Native system, when the 12-factor guidelines seem to be all about stateless containers, but is it? It’s unclear and this confusion may lead to poor technology stack choices that are impossible or extremely hard to change later on as your system evolves in terms of demand and performance.
While stateless systems are easier to work with, the reality is that we live in a stateful world, so we have to handle the state of data accordingly to ensure data integrity beyond securing it.
We will examine and demonstrate the fundamentals of a Cloud Native system with Stateful Microservices that’s built with Open Liberty and MicroProfile.

JCON_Adressing the transaction challenge in a cloud-native world.pptxGrace Jansen
With microservices comes great benefits but also great challenges! One such challenge is data consistency and integrity. Traditionally, tightly coupled transactions were used to ensure strong consistency and isolation. However, this results in strong coupling between services due to data locking and decreasing concurrency, both of which are unsuitable for microservices. So, how do we provide consistency guarantees for flows that span long periods of time in cloud-native applications? We'll address this challenge by investigating the Saga pattern for distributed transactions, the MicroProfile Long Running Action (LRA) specification and how these can be used to develop effective cloud-native Java microservices.

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.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.

30. Reactive Systems Explained
Enterprises are busy transforming themselves by building
applications capable of handling massive scale, enormous
amounts of data, or both. The good news? There’s an
unprecedented choice of open source technologies available to
pursue these next-generation applications. In this book,
enterprise developers, architects, and tech leads will examine the
factors driving so many organizations to build reactive systems
for cloud native development. You’ll learn the key patterns of
reactive systems and draw distinctions between
implementations offered by various toolkits and frameworks.

Creation of the Reactive Manifesto in 2013, by Jonas Bonér
to collaborate and solidify what the core principles were for building reactive applications and systems
REACT to users (Responsive)- user click a button
REACT to load (Elastic) - black friday and login/book table
REACT to failure (Resilient) - monitor, replace service
REACT to events (event-driven) - achieve other 3 principles
how do we achieve this? same way bees do
async comm - dancer bee, guard bee recruiting
Let’s say that our system should:
. Be responsive to interactions with its users
. Handle failure and remain available during outages
. Strive under varying load conditions
. Be able to send, receive, and route messages in varying network conditions
These answers actually convey the core reactive traits as defined in the manifesto.
It is important to realize that reactive traits not only set you up for success right now, but also play very well with where the industry is headed, toward location-transparent, ops-less distributed services.
bees = sophisticated system, appear simplistic, actually complicated
efficient society of independent individuals acting as a whole
We want to mimic what bees have achieved - tall ask, bees have had millennia, but by implementing reactive architecture we can start to achieve this
If it’s our goal to build responsive applications in an event-driven world, we need to be making sure we are getting the most out of the hardware on which we’re running. We do this through concurrency and parallelism.
Reactive programming is one tool which aims to try and tackle this.
Reactive programming is a great technique for managing internal logic and dataflow transformation, locally within the components, as a way of optimizing code clarity, performance and resource efficiency.
Reactive systems puts the emphasis on distributed communication and gives us tools to tackle resilience and elasticity in distributed systems.
Reactive programming is a paradigm in which declarative code is used in order to construct asynchronous processing pipelines.
Translated, this is essentially the same process our minds perform when we try to multitask. Rather than true parallel tasking, we actually switch tasks and split those tasks efficiently during their duration. This method of switching tasks enables us to efficiently use our time instead of having to wait for the previous task to complete. This is exactly what reactive programming was created to enable and is an event-based model in which data is pushed to a consumer, as it becomes available turning it into an asynchronous sequences of events.
Reactive programming is a very useful implementation technique for managing internal logic and dataflow transformation, locally within components. However, once there are multiple nodes, there is a need to start thinking hard about things like data consitency, cross-node communication, orchestration, failure management, separation of concerns and responsibilities, etc, i.e. there is a need to think about system architecture. Reactive programming cannot address these issues or address the need for resilience and elasticity within a system. So, instead, to maximize the value of reactive programming, it’s recommended to use it as a tool to build a reactive system.
Architectural tools – enable reactive behaviours
Sphere of knowledge or activity
Subject area on which the application is intended to apply
Development approach as opposed to a physical tool
Aims to ease the creation of complex applications – divides up large systems into bounded contexts
A DDD aggregate is a cluster of domain objects that can be treated as a single unit.
An aggregate will have one aggregate root.
DDD = independent areas of a problem as bounded contexts, emphasises a common language to talk
Any references from outside the aggregate should only go to the aggregate root. The root can thus ensure the integrity of the aggregate as a whole. How do we achieve efficient communication across these bounded contexts/services?
Focus on the core domain and domain logic.
Base complex designs on models of the domain.
Constantly collaborate with domain experts, in order to improve the application model and resolve any emerging domain-related issues.
Message-driven
Lagom framework
Communication between Microservices needs to be based on Asynchronous Message-Passing
An asynchronous boundary between services is necessary in order to decouple them, and their communication flow, in time—allowing concurrency—and in space—allowing distribution and mobility. Without this decoupling it is impossible to reach the level of compartmentalization and containment needed for isolation and resilience.
Asynchronous and non-blocking execution = more cost-efficient through more efficient use of resources, minimizes contention (congestion) on shared resources in the system, which is one of the biggest hurdles to scalability, low latency, and high throughput.
It’s best illustrated with an example… bees queuing = wasted resource, equivalent to threads
But why is blocking so bad?
The fundamental shift is that we’ve moved from "data at rest" to "data in motion.
Applications today need to react to changes in data in close to real time—when it happens
First Wave = data at rest, batch processing, hours of latency, overnight
Second Wave = hybrid architecture, lambda architecture, 2 layers (batch and speed layers), added needless complexity – 2 data pipelines and need to merge them afterwards
Third Wave – fully embrace data in motion, stream processing architecture, event logging/sourcing…..
Lagom framework
Message-driven / responsiveness
Event Sourcing ensures that all changes to application state are stored as a sequence of events
(e.g. business objects is persisted by storing a sequence of state changing events)
Command Query Responsibility Segregation --> disassociate writes (commands) and reads (queries)
Applying event sourcing on top of CQRS means persisting each event on the write part of the application.
Read part is derived from the sequence of events.

Bees can query their own brains (read)

Form of Database partitioning, separates very large databases into smaller, faster, more manageable parts called data shards
Shard = small parts of a whole
Meant to make v. large databases more manageable
Greater parallelism, without collisions
Two bees at the same cell – fill up multiple cells (sharding)
Finite space in the hive – sharding out the hive into cells – operate in parallel across cells, reducing contention
Imagine one huge cell, only one bee can fill up at a time
Resiliency/elasticity
Lagom framework
Form of feedback/flow control
Without feedback, a distributed system can easily become unstable and fail. Any component that cannot support the worst possible case of loading in the system can become a bottleneck. BLOCKING
Without Feedback, other components will continue to increase the load until they are in turn congested, resulting in the ultimate collapse!
When one component is struggling to keep-up, the system as a whole needs to respond in a sensible way.
It is unacceptable for the component under stress to fail catastrophically or to drop messages in an uncontrolled fashion.
Since it can’t cope and it can’t fail it should communicate the fact that it is under stress to upstream components and so get them to reduce the load.
This back-pressure is an important feedback mechanism that allows systems to gracefully respond to load rather than collapse under it.
this mechanism helps ensure that the system is resilient under load, and will provide information that may allow the system itself to apply other resources to help distribute the load, see Elasticity.
Backpressure = built wherever the publisher is faster than the subscriber

For the actor model it's relatively fine-grained, in that an actor tends to represent the equivalent of one object in Object Orientated Programming.
For micro-services it's relatively coarse-grained, in that a single micro-service may consist of a large number of actors or objects.
An actor is the thing that receives a message and does some kind of computation based on it. When you hear of an actor, think of it as a computer process or a function - you're going to pass a message to, kind of like calling a function. Basically you send the actor instructions and it returns some information back to you.
The idea is very similar to what we have in object-oriented languages: An object receives a message (a method call) and does something depending on which message it receives (which method we are calling).
The main difference is that actors are completely isolated from each other and they will never share memory.
Actors are part of an actor system and can be arranged in a hierarchy. This means they can split up and delegate tasks to child actors. The child actor is supervised and delegate their failure back to their parent actor.
In the actor model everything is an actor and they need to have addresses so one actor can send a message to another. You can also assign one address to multiple actors. This way you can scale your application to meet traffic demands if one actor is not enough.
Actors communicate with each other by sending asynchronous messages. Those messages are stored in other actors' mailboxes until they're processed.
Actors are not suitable when you need a sequential order of things to happen.
If you find yourself sending multiple messages and then needing to rollback those processes if one fails, you might want to reconsider using the Actor Model. A common example of this is a bank account.
If you are building an application that handles tasks asynchronously, using the Actor Model can help simplify your code. It will allow you to scale your application and process tasks in parallel.
Vert.x is based on a flat hierarchy and does not implement the actor model. Instead, it is based on the event loop model.
The unit of execution in Vert.x is known as a Verticle. It processes incoming events over event-loops, which are typical in asynchronous programming models.
Verticle is a class whose state is totally inaccessible from outside except through event bus. So messages come, queued, and popped sequentially in a single thread manner. The idea is to create a thread-safe environment without having to deal with Java’s locking mechanism.
Similar to Akka, Vert.x also supports point-to-point and a publish-subscribe pattern. A difference is the message passing of Vert.x is language agnostic and uses JSON to pass data, whereas Akka uses specific objects from either Scala or Java.
Akka provides an additional component known as Akka Persistence that can be used to store the internal state of an actor. This enables the state of an actor to be recovered if it crashes. Currently, Vert.x does not provide out-of-the-box recovery capabilities.
People argue that due to its complexity, Akka tends to have a much larger learning curve than Vert.x. it’s said that Akka needs more understanding and mastery of the actor model and async architectures in order to use it effectively.
However, Akka is more mature, had more features (Akka streams, Akka perstistence, Akka clusters).
