Badass Microservices - deploy, build & scale your apps with Payara Micro
Talk by Navin Surtani presented at Devoxx Belgium 2015 Building on the Java EE 7 support of its GlassFish 4.1 core Payara Micro is a super-lightweight container for you to deploy your applications from the command line without needing to install a full-blown application server. With its automatic and elastic clustering, it is designed for running Java EE applications in a modern containerized/virtualized infrastructure. As each Payara Micro server will automatically cluster with other servers on the network your Java EE application can be elastically scaled horizontally by adding and removing containers based on demand. In this talk, Navin Surtani will demonstrate the ease of deployment of applications and services to Payara Micro, along with showing how simple it is to build and scale a cluster of instances running these services.

Editor's Notes
- * Microservices! Yeah buzzword!
- * Mention that Payara Micro is the platform that we will use to deploy our micro services to.
- “Sometimes it’s not so educational to talk about what something is.” “Instead, let’s talk about what Payara Micro isn’t” Ultimately, this isn’t about deploying monolithic applications.
- We are waiting to be let out of that cage to go and build our micro service architecture We are all happy and excited at the prospect of doing that ! But we still have a lot of old, EE code in there - that’s required for our business functionality ! We can’t just re-write everything from scratch

- * After all, some of these EE API’s are quite useful
- It worked! What did we learn from that? Relatively fast start-up Simple auto-cluster-discovery
- My sucky JSON-generator held up long enough!
