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.
By 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.
