Finagle-Based Microservices at SoundCloud
From https://www.eventbrite.com/e/finaglemeetup-at-twitter-hq-tickets-12857666627
Three Years of Microservices at SoundCloud - Distributed Matters Berlin 2015
SoundCloud is the largest repository of audio on the web, used by more than 200 million people every month, who upload more than 11 hours of audio every minute. Like so many others, we have migrated from a typical monolithic architecture to microservices. While the benefits brought by this style of SOA to our productivity and reliability are clear, the architecture required some non-obvious changes in the way we operate systems, and a way to tackle the overhead associated with having hundreds of small moving parts to serve every request. In this talk we’ll share the toolkit and strategy SoundCloud uses to keep its microservices explosion manageable. What do we do about the operations overhead? How to spread devops skills across teams to support the “you build it, you run it” vision? How to deal with breaking changes and asynchronous behaviours? How to deal with chatty interactions? Which protocol? How do I even get a diagram telling me how all this stuff is put together?

R2DBC - Good Enough for Production?
Solution for the reactive relational DB connection when programming using Spring WebFlux. When you want all you app to be reactive, don't make JDBC DB connection a bottlenack. Use R2DBC driver. In the presentation I share my experience on how to work with the driver, and if it is already ready to be used in serious projects on production. The talk was presented at Devoxx Ukraine, Nov 1, 2019.

Istio service mesh & pragmatic microservices architecture
Microservices architecture has changed how companies develop and deploy applications. This change has affected testing process as well. New techniques have emerged and others have been enhanced. Does your organization wish to achieve unicorn like speed? With N deploys per day? Or a lead time (time to business value from idea to production) measured in days/weeks instead of months/years? In this session, we will not only describe how to use Istio and Kubernetes but actively demonstrate 3 specific techniques that you can use immediately following the session.
Currently, Istio is gaining a lot of traction as service-mesh implementation for Kubernetes. In this session, we are going to explore how to install Istio, and how to use it to release new versions of our services correctly.
Istio Service Mesh & pragmatic microservices architecture
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.

Kubernetes Native Java
Kubernetes is becoming the de-facto platform to deploy our application nowadays. But this movement also implies some changes in the way we code our applications. Before this change, we just developed a monolith application where everything was up and running up front, now we are breaking down this monolith into (micro)services architecture and everything is interconnected with the network. Although it might seem easy, done properly is not an easy as there are some challenges to address that was not in a monolith architecture.
In this session, we’re going to start discussing what are these challenges (ie fault tolerance, service discovery, open tracing, or health checks) and demonstrate how they can be solved using Eclipse MicroProfile specification.
Come to this session to learn how to develop a successful Kubernetes-Native application using Quarkus, a Java ecosystem way to develop cloud-first, container-native, serverless focused and Kubernetes optimized.

KUBEBOOT - SPRING BOOT DEPLOYMENT ON KUBERNETES
Have you ever thought how to deploy Cloud Native Java Applications (Spring Boot) on Kubernetes? Kubernetes has now become a de-facto standard for deploying Cloud Native Applications, but still there is myth that they are not ready for Java workloads. The aim of this session is to break that myth to show Kubernetes is well suited for Cloud Native Java applications.
The session explores the cloud native characteristics such as Discovery, Blue/Green Deployments, Elasticity, Canary Deployments, Resiliency, Pipeline(CI/CD), Authentication etc., becomes implicit characteristics to your Spring Boot Java applications that are deployed on Kubernetes
In this session, we will see how to build, debug, deploy and discover Spring Boot applications on Kubernetes, covering in depth details of the tools, libraries and platform that could be used to make your spring boot deployment smooth and easy.
Building a smarter application stack - service discovery and wiring for Docker
There are many advantages to a container based, microservices architecture - however, as always, there is no silver bullet. Any serious deployment will involve multiple host machines, and will have a pressing need to migrate containers between hosts at some point. In such a dynamic world hard coding IP addresses, or even host names is not a viable solution.
This talk will take a journey through how Yelp has solved the discovery problems using Airbnb’s SmartStack to dynamically discover service dependencies, and how this is helping unify our architecture, from traditional metal to EC2 ‘immutable’ SOA images, to Docker containers.

What monolith can learn from microservices?
Nowadays everyone is talking about microservices and how cool they are. That’s true, but not all business needs to move to microservices, you can still use monolith architecture and make it more fashion by applying some of the design/elements that you’ve learned from microservices architecture.
Can you use circuit breaker pattern, service isolation, event-driven and non-blocking application, cloud-native approach or zero downtime deployment in monolith architecture? Is it worth? The answer is YES!!!.
Come to this session to learn how to make your Java monolith applications attractive again by borrowing some of the principles of microservices architecture.

Zero Downtime Deployment in Microservices era
ou joined the DevOps movement and want to release software even faster and safer. You started reading about Advanced deployment techniques like Blue-Green Deployment, Canary Releases or Dark Shadow Technique. But how do you implement them without disrupting your users in production? With Zero Downtime! This is easy with your code, but what about ephemeral and persistent states? Most of the examples out there does not tackle this scenario (which is the most common in real systems). Come to this session and you’ll learn in a practical way how you can achieve zero downtime deployments applying advanced deployment techniques for maintaining the ephemeral and persistent state of your microservice application.
Deploy With Confidence
In a monolithic application, different services are developed within same project side by side.
In these kind of applications you don't need to worry about breaking the compatibility between contract interfaces since there is an invisible verifier called compiler that checks that all method calls follows the defined signature.
But in case of microservices, different services are deployed in different runtimes and using different separated networks.
In this scenario, any change on the contract of one service cannot be caught by the compiler since there is no typesafe connection between services..
Now breaking the compatibility between services can be really easy and hard to detect (maybe until your new version of the service is on production).
In this talk we are going to explore why deploying a new version of a service might break everything in microservices architecture, and how to fix with consumer-driven contracts pattern.
Reactive Programming for Real Use Cases
Probably you are curious about this thing called Reactive Programming. Reactive Programming is another programming paradigm that in most of the cases, we are not used to coding in our day-to-day work, as the imperative way is the common one. This makes learning and thinking in a reactive way harder. One of the main problems I have found when learning and reading material about Reactive Programming is that they never tackle enterprise use cases. In this session, we are going to skip the cute ideas that are normally part of a reactive programming talk and focus on how to use it in the real world. Don't be the last developer to board this train and move your reactive skills from novice to expert.

Microservices testing and automation
DevOps has grown in popularity in recent years, particularly in (software) companies that want to reduce lead time to be measured in days/weeks instead of months/years. If you want to make sure your software does the right things and does things right, you need to test it implacably. The big problem is that companies see is the testing phase as the bottleneck—and it is—of the process slowing down product release. To change that, we need a new way of testing our applications, making the release process of an application a testing process as well and involving the QA from the beginning within the team. QAs are not a separate team anymore (DevTestOps). How is the testing pyramid affected? In this session, we will not only describe, but actively demonstrate several techniques that you can use immediately to start testing in production and speed up your release cycle to unimaginable limits.

Supersonic Subatomic Java
Java was born in the mid-90s, the era of TLC and Boyz II Men, long before the rise of Linux server virtualization and the Linux container.
We took great pride in running Java applications for weeks if not months without restarts and Java assumed the whole computer belonged to itself, that it could consume all available memory and CPU. In this presentation, we will demonstrate the problems associated using Java for "microservices", and how the open source ecosystem is working to insure the future of Java by being cloud first, container native, serverless focused and Kubernetes optimized. This is where GraalVM meets Quarkus, bringing server-side and enterprise-capable Java to enable you to build truly cloud native apps
From DevTestOops to DevTestOps
DevOps is growing in popularity in last years, particularly in (software) companies that want to reduce its lead time (time to business value from idea to production) measured in days/weeks instead of months/years?
If you want your software to do the right things and do these things right, you need to test it implacably.
The big problem is that companies see (and it is) the testing phase as the bottleneck of the process slowing down product release. To change that, we need a new way of testing our applications, making the release of an application a testing process as well, and involve QA since the beginning within the team. QAs are not a separate team anymore (DevTestOps).
What is the role of QAs in this new approach? How is the testing pyramid affected? How you can fail on trying to speed up release frequency?
In this session, we will not only describe but also actively demonstrate several techniques that you can use immediately following the session for testing applications like unicorns.
Supersonic, Subatomic Java
In a cloud native world enamored of Microservices and Serverless, meet Quarkus - Java’s brilliant response to technologies like Node.js, Python and Go that had until recently proven quicker, smaller and arguably more nimble. But we know seeing is believing - we’ll show you Quarkus in action. Get ready to experience “Supersonic, Subatomic Java” - and make Open Source frameworks like Hibernate and Apache Camel faster, smaller and more dynamically scalable than ever before.

Zero Downtime Deployment in Microservices era
You joined the DevOps movement and want to release software even faster and safer. You started reading about Advanced deployment techniques like Blue-Green Deployment, Canary Releases or Dark Shadow Technique. But how do you implement them without disrupting your users in production? With Zero Downtime! This is easy with your code, but what about ephemeral and persistent states? Most of the examples out there does not tackle this scenario (which is the most common in real systems). Come to this session and you’ll learn in a practical way how you can achieve zero downtime deployments applying advanced deployment techniques for maintaining the ephemeral and persistent state of your microservice application.
Testing XXIst Century
Microservices architecture has changed how companies develop and deploy applications. This change has affected testing process as well. New techniques have emerged and others have been enhanced.
Come to this session to learn about service virtualization, contract testing or testing in production to increase deployment velocity from 1 week to N times per day or deploy each service independently without worrying about breaking the compatibility between services anymore.
Arquillian Constellation
There's been a lot of movement in the Java EE world. From the release of its 8th edition to the shift to Eclipse Foundation and recent rebranding to Jakarta EE. At the same time Eclipse MicroProfile shown up on the EE scene with the primary goal of evolving the spec towards microservice architectures.
With all these changes happening rapidly what has happened to Arquillian, the de-facto testing tool for Java EE applications?
Come to this session, you are going to explore the new and noteworthy of the Arquillian constellation. How standard Arquillian tests has been simplified as well as how microservice architecture has impacted on Arquillian offering integrations for polyglot persistence tests, contract testing or deployment tests for Docker, Kubernetes, and Openshift.
You'll learn that Arquillian is not only for Java EE.
Testing for Unicorns
One of the most important benefits of automated testing is to ensure a fast and safe code refactoring to evolve our system architecture. The main problem is how to write tests that are easy to write, easy to follow and not time consuming during development nor execution time. In this session, we are going to explore some powerful Java testing libraries that will help you write better (unit) tests focusing on the main Unicorns architecture challenges such as validating microservices endpoints, remote calls to other microservices or just asynchronous/reactive code.
Testing in the 21st Century (ExpoQA)
Microservice architectures have changed how companies develop and deploy applications, and have therefore in turn affected the testing process as well. New techniques have now emerged and others have been enhanced, while old testing techniques (used in monolith) drive us to a dead-end when we try to apply them to a microservices architecture.
In this master class, Alex Soto will introduce some testing techniques, such as service virtualization, contract testing and testing in production to increase deployment velocity from 1 week to N times per day and deploy each service independently without worrying about breaking the compatibility between services. He will show you several examples in Java but will also point out resources for other languages as well.
After this theoretical and live code master class, you'll understand how to test microservice architectures and reduce the friction between trying to apply old testing techniques to a new paradigm.
10 Testing libraries any Java developer should know
Java language is one of the most successful languages nowadays with more than 20 years of history. This means that a lot of tools libraries has been developed around all this time for production code but also for testing code.
Come to this session to learn 10 testing libraries that can have a really positive impact on how to write tests, but more importantly, also how to make them more readable.
Testing Java Microservices Workshop
With traditional software unit tests, there's never a guarantee that an application will actually function correctly in the production environment. And when you add microservices, remote resources that are accessible over a network, into the mix, testing is more tricky. To make things even harder, microservices typically need to collaborate with additional network-based microservices, making testing even more challenging. Moving to microservices implies a change in the mindset of developers, so will using old testing techniques with new architectures still work?
In this session, you'll learn test strategies that solve the most common issues likely to be encountered when writing tests for a microservices architecture. We will look at how tools such as Arquillian, JUnit, Docker and techniques such as service virtualization, consumer-driven testing and testing in production with Istio can aid in accomplishing this task.
Testing in the 21st Century
Microservices architecture has changed how companies develop and deploy applications. This change has affected testing process as well. New techniques have emerged and others have been enhanced.
Come to this session to learn about service virtualization, contract testing, smart testing or testing in production to increase deployment velocity from 1 week to N times per day or deploy each service independently without worrying about breaking the compatibility between services anymore.
TEST SMARTER AND GAIN SOME TIME BACK
“A programmer is an organism capable of converting coffee into code.”
The best excuse for a 5-minute coffee break used to be “my code is compiling,” and these days we have “my tests are running.” It's a huge waste of developer time and continuous integration resources to have such long-running tests. But what’s even more important, it slows down development and deployment velocity, resulting in slower time to market and greater lead times.
Join this session for a smart solution to this problem. We’ll show you how a new Java™ tool can drastically reduce your test execution time, letting you stay in the zone and increasing your personal productivity and velocity. Caveat: You may have to find a different excuse to get coffee.
Deploy And Release at Kubernetes Era
Microservices architecture has changed how companies develop, deploy and release applications. Some technologies such as Docker and Kubernetes has emerged to simplify how to put applications into production, increasing the release velocity from months to N times per day.
If you are into DevOps bandwagon, come to this session to learn how Kubernetes and Istio (the new Crown jewel) can help you on reducing the lead time (time to business value from idea too production) and start releasing at unicorn speed.
Sail In The Cloud
Microservices architecture has changed how companies develop and deploy applications. This change has affected testing process as well. New techniques have emerged and others have been enhanced. Does your organization wish to achieve unicorn like speed? With N deploys per day? Or a lead time (time to business value from idea to production) measured in days/weeks instead of months/years?In this session, we will not only describe how to use Istio and Kubernetes but actively demonstrate 3 specific techniques that you can use immediately following the session.
Testing in the 21st Century
Microservices architecture has changed how companies think, develop and deploy applications. But this change has affected testing process as well. New techniques has been emerged and others has been enhanced. Come to this session to learn about service virtualization, contract testing or testing on production.

Graspan: A Big Data System for Big Code Analysis
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.
