Coimbra JUG – Just Enough App Server

posted by Roberto Cortez on

The Fifteen Meeting of Coimbra JUG was about Application Servers. For a long time, developers complain about Application Servers. Developers find them heavyweight and the current trend is to develop lightweight, isolated and contained services. Most call this approach Microservices. In my opinion, there is not a 100% accepted definition of what a Microservice is, but this is another story. Anyway, are Application Servers prepared to answer the new demands? António Gonçalves has the answer in is new session. Have a look and decide for yourself:

Just Enough App Server

Are Websphere or Weblogic appropriate for your project? Too big” ? Do Jetty or Tomcat actually meet your needs? Too “small”?

Neither too big nor too small. What you need is “just enough app server” to support only the subset of APIs and services your application needs.

In this session I will make an inventory of Java EE application servers (Weblogic, Websphere, JBoss, GlassFish), Profile Web (Tomee, Payara, Siwpass) and Servlets (Tomcat, Jetty, Undertow). If Microservices is want you want, I will introduce other modular solutions such as WildFly Swarm, KumuluzEE, Spring Boot or Dropwizard. I will talk about performance, war, executable jar, monitoring, management, optimization, use cases and some personal feedback… all this by showing code and executing several types of applications (from the simplest to more complex) in several kinds of containers … and maybe even on a Raspberry Pi.
