Description

Some enterprise developers might wonder whether the Java EE platform is eligible for realizing modern, containerized enterprise applications that run in cloud offerings.
A lot of enterprises migrate their runtime environments to platforms that are based on Docker and Kubernetes.

Container technologies, in combination with orchestration, provide significant advantages in the way companies deploy and operate their enterprise software.

This raises the question: Are enterprise applications developed with Java EE eligible for these technologies; if so, how can this transition be accomplished?

This course will show you how it is possible to develop Java EE 8 applications that run in containers. We will see why Java EE specifically is a natural fit for containers.

This course starts with practical ways on how you can use Docker in Java EE 8 and how to troubleshoot containers. You will run Java EE in containers. This course will also teach you how to configure containerized applications. Also you will orchestrate containers using Kubernetes.

By the end of the course, you will be able to Integrate Java EE applications into Kubernetes.

All the code and supporting files for this course are available on Github

Excellent overview course. Nicely tied into the JavaEE focus. Could include some more in-depth details. Like Spring-Boot embedded app servers.

Sebastian is very clear, concise, and engaging. I found his examination of how to jointly configure Docker, Kubernetes, and JavaEE to be consistently coherent and thorough.

as always small examples but the real world applications with business logic and multiple layers are not covered... and EAR files are still needed if you want to REUSE the Business logic part or is there a other solution

Overall course is good, a lot of things have been included in 3hr. But, as I think, some important things like running few replicas, demonstration of autoscaling and loadbalancing features is a must for such course. Anyway, thanks a lot!
