A few weeks ago, Nginx released its multilanguage microservices-friendly app server, but without Java support at launch. Now IBM has a beta build of its own microservices-friendly app server for Java applications: the open source Open Liberty, which implements IBM’s version of Java EE and MicroProfile microservices implementation.
Open Liberty will provide a runtime supporting Java microservices that can be quickly updated and moved among different cloud environments. When combined with the Eclipse OpenJ9 Java Virtual Machine, OpenLiberty will provide a full Java stack, IBM said. (OpenJ9 had been IBM’s J9 JVM, which it contributed to the Eclipse Foundation that now manages Java EE.)
