We heard Red Hat’s Edson Yanaga explain how\, and also how Google’s Kubernetes was used to wrap and dep loy Docker into production. \n\n Edson presented… \n\n Migrating to Micr oservice Databases: From Relational Monolith to Distributed Data \n\n and \n\n Kubernetes for Java / Docker Developers \n\n Doors Open 14:00 (aftern oon session) / 18:15 (evening session) \n\n . \n\n This month\, for only t he second time in our ten year history\, we are hosting our meetup on a Su nday. We are incredibly privileged to welcome Edson Yanaga\, Red Hat's Dir ector of Developer Experience. \n\n Edson is a Java Champion and a Microso ft MVP. He is also a published author and a frequent speaker at internatio nal conferences\, discussing Java\, Microservices\, Cloud Computing\, DevO ps\, and Software Craftsmanship. \n\n Yanaga considers himself a software craftsman and is convinced that we all can create a better world for peopl e with better software. His life's purpose is to deliver and help develope rs worldwide to deliver better software faster and safely - and he can eve n call that a job! \n\n You can follow him on twitter at @yanaga \n\n . \n \n Migrating to Microservice Databases: From Relational Monolith to Distri buted Data \n\n In a distributed system with multiple moving parts\, which is the case of Microservices\, we can’t allow that a single complement downtime breaks down the entire system. Dealing with stateless code is eas y\, but it gets much harder when we have to deal with persistent state. In this scenario\, zero downtime migrations are paramount to guarantee integ rity and consistency. \n\n Within all the Microservices characteristics\, undoubtedly the one that creates more perplexity is the “one database pe r Microservice”. However\, very few teams have the privilege of starting something from scratch: most of the times they have a legacy database tha t will survive any new implementation. \n\n In legacy systems you traditio nally have a model that adopts transactions\, strong consistency\, and CRU D. In order to guarantee integrity and consistency with zero downtime\, we must reassess some of these concepts. In this talk we’ll discuss strong and eventual consistency\, CRUD and CQRS\, Event Sourcing\, and how these techniques relate to each other in many different integration and evoluti on strategies for relational databases. We’ll explore Views\, Materializ ed Views\, Mirror Tables\, Event Sourcing/Streaming\, Data Virtualization\ , Change Data Capture\, and how these strategies enable you to build up a Microservices architecture from a legacy monolithic relational database. \ n\n Download Edson's recently released O'Reilly book \n\n Kubernetes for J ava / Docker Developers \n\n Yes\, Docker is great! We are all very aware of that but now it’s time to take the next step: wrapping it all and dep loying to a production environment. For this scenario\, we need something more. For that “more” we have Kubernetes by Google - a container platf orm based on the same technology used to deploy billions of containers per month on Google’s infrastructure. \n\n Ready to leverage your Docker sk ills and package your current Java app (WAR\, EAR or JAR)? Come to this se ssion to see how your current Docker skillset can be easily mapped to Kube rnetes concepts and commands. And get ready to deploy your containers in p roduction! \n\n . \n\n REGISTRATION NOTES \n\n The Dublin Java User Group meetups are designed to enhance the knowledge of developers and technology professionals. \n\n Due to the overwhelming demand to attend our events t hey are always full.
