What is Payara Micro?
Payara Micro – Small. Simple. Serious.
Payara Micro is the open source, lightweight middleware platform of choice for containerized Java EE (Jakarta EE) microservices deployments. Less than 70MB in size, Payara Micro requires no installation or configuration and no need for code rewrites – so you can build and deploy a fully working app within minutes.
Compatible with Eclipse MicroProfile, Payara Micro is the microservices-ready version of Payara Server. You can run war files from the command line without any application server installation. Automatic and elastic clustering makes Payara Micro ideal for running Java EE applications in a modern virtualized infrastructure.
Payara Micro also comes with a Java API so it can be embedded and launched from your own Java applications – see how.
