The decline of the big Application Server

Following on the Spring Boot tutorial, it seems that we have moved away from the large Application Servers that I used to deploy a WAR to. It has Tomcat, Jetty and Undertow. When I worked in the JEE world we used WebLogic, Jetty was just becoming a thing, and I honestly didn’t pay it much attention. But I just read this really interesting article about how things have moved on.

It makes sense, especially in this whole microservices landscape. I’m learning a bit about how to configure aspects of the application server now. I must admit that I didn’t really understand this too much at the time either. I just coded, other people set this up for me to deploy to, but I always felt a bit concerned that I didn’t understand how to properly configure the application servers. In this whole new DevOps world, I guess I’ll have to look at this too.
