Payara Micro

Small, Simple, Serious

Payara Micro, compatible with Eclipse MicroProfile, enables you to run WAR files from the command line without any application server installation. 

It is small, <70 MB in size, and incredibly simple to use. With its automatic and elastic clustering, Payara Micro is designed for running Java EE applications in a modern containerized / virtualized infrastructure, using automated provisioning tools like Chef, Ansible or Puppet.

That’s not all! Using the Hazelcast integration, each Payara Micro process will automagically cluster with other Payara Micro processes on the network, giving web session resilience and a fully distributed data cache using Payara’s JCache support.

Payara Micro also comes with a Java API so it can be embedded and launched from your own Java applications - see how.

Eclipse MicroProfile

Eclipse MicroProfile is a specification for a set of APIs appropriate to building microservices. The project was announced in June 2016 by a number of Java industry vendors & community groups including Payara, RedHat, IBM, Tomitribe, LJC and SouJava. Within three months of the initial announcement, Payara MicroProfile 1.0 had been released.

The MicroProfile is a baseline platform definition that optimises Enterprise Java for a microservices architecture and delivers application portability across multiple MicroProfile runtimes. The initially planned baseline is JAX-RS + CDI + JSON-P, with the intent of community having an active role in the MicroProfile definition and roadmap.

Both Payara Micro and Payara Server are now compatible with Eclipse MicroProfile.

How Micro is Payara Micro? - the whole philosophy of Payara Micro is to turn the idea of application servers on its head and change the perception that they are large, complex and unwieldy environments for building server side applications. So as part of our development we've done some analysis of how small the core runtime of Payara Micro is.

Deploy, Build and Scale Your Apps with Payara Micro - this recording of the Quickie session delivered at Devoxx 2015 conference in Belgium demonstrates the ease of deployment of applications and services to Payara Micro, along with showing how simple it is to build and scale a cluster of instances running these services.
