From Red Hat
Edson Yanaga, Red Hat's Director of Developer Experience, is a Java Champion and a Microsoft MVP. He is also a published author and a frequent speaker at international conferences, discussing Java, Microservices, Cloud Computing, DevOps, and Software Craftsmanship.
Yanaga considers himself a software craftsman, and is convinced that we all can create a better world for people with better software. His life's purpose is to deliver and help developers worldwide to deliver better software faster and safely - and he can even call that a job!
In a Microservices architecture with multiple moving parts we can’t allow that a single complement downtime breaks down the entire system. Dealing with stateless code is easy, but it gets much harder when we have to deal with persistent state. In this scenario, zero downtime migrations are paramount to guarantee integrity and consistency.
Within all the Microservices characteristics, undoubtedly the one that creates more perplexity is the “one database per Microservice”. However, very few teams have the privilege of starting something from scratch: most of the times they have a legacy database that will survive any new implementation.
In legacy systems you traditionally have a model that adopts transactions and CRUD. Now we must reassess some of these concepts. In this talk we’ll discuss consistency, CRUD and CQRS, Event Sourcing, and how these techniques relate to each other in many different integration strategies for databases. We’ll explore Views, Materialized Views, Mirror Tables, Event Sourcing, Data Virtualization, Change Data Capture, and how these strategies enable you to build up a Microservices architecture from a legacy monolithic relational database.
Mastering Deployments with Kubernetes & OpenShift: from Basic to Zero Downtime, Blue/Green, Canary and A/B
The “deploy moment” is an occasion that still gives many developers the shivers. But it shouldn’t be this way (at least not every time). Luckily enough, we have tools and processes today that enable us to turn the deploy moment into an usual activity. Gone where the days when we had to automate everything by hand. Today we have Kubernetes, OpenShift, and Fabric8 to automate out-of-box many different scenarios. And if we need even more advanced scenarios we can use tools like Zuul and FF4J to solve the cumbersome parts for us.
Come and join this live demo session with lots of different deployment scenarios: from basic to advanced. We'll cover the basic deployment concepts and then we'll dig into demoing how can we use open source tools like Kubernetes, OpenShift, Fabric8, Zuul and FF4J to master the deployment art.
