Chapter 42. KIE Server

KIE Server is the server where the rules and other artifacts for Red Hat Decision Manager are stored and run. KIE Server is a standalone built-in component that can be used to instantiate and execute rules through interfaces available for REST, Java Message Service (JMS), or Java client-side applications, and Red Hat build of OptaPlanner functionality through solvers.

Created as a web deployable WAR file, KIE Server can be deployed on any web container. The current version of the KIE Server is included with default extensions for both Red Hat Decision Manager and Red Hat Process Automation Manager.

KIE Server has a low footprint with minimal memory consumption and therefore can be deployed easily on a cloud instance. Each instance of this server can open and instantiate multiple containers, which enables you to execute multiple rule services in parallel.

KIE Server can be integrated with other application servers, such as Oracle WebLogic Server or IBM WebSphere Application Server, to streamline Red Hat Decision Manager application management.
