Trends at JavaOne 2016: Microservices, Docker and Cloud-Native Middleware

5,292 views

Published on

In addition to focusing on many related concepts like container or service discovery, technologies like Docker and cloud platforms, my session also discussed ten lessons learned from building cloud-native middleware microservices together with our customers in the last months.

The demo brings this from theory to practice by showing how to deploy a single (i.e. built just once) TIBCO BusinessWorks Container Edition microservice to different cloud and container platforms: Docker, Kubernetes and Pivotal CloudFoundry. The video also shows how to leverage other cloud-native open source frameworks such as Consul and Spring Cloud Config for distributed configuration management and service discovery of middleware microservices.

It can be described as "software glue”. Middleware makes it easier for software developers to implement communication and input/output, so they can focus on the specific purpose of their application.” Wikipedia (https://en.wikipedia.org/wiki/Middleware) Middleware
