Small download and HD size, fast startup and deployment, nicely integrated with NetBeans and all other IDEs (it is basically a Tomcat on steroids). Even the fully loaded "plus" version is surprisingly small and fast with commercially available support directly from tomitribe. Another great "microservices" server. TomEE supports Java EE 7 well, however it is not officially certified (yet?).
This blog is running on TomEE without a restart for > 1 year.
On demand workshops: Java EE 7: Bootstrap, Effective, Testing and Microservices available for streaming.
