Chapter 4. Project deployment options with Red Hat Decision Manager

Deployment to an OpenShift environment

Red Hat OpenShift Container Platform combines Docker and Kubernetes and enables you to create and manage containers. You can install both Business Central and KIE Server on OpenShift. Red Hat Decision Manager provides templates that you can use to deploy a Red Hat Decision Manager authoring environment, managed server environment, immutable server environment, or trial environment on OpenShift. With OpenShift, components of Red Hat Decision Manager are deployed as separate OpenShift pods. You can scale each of the pods up and down individually, providing as few or as many containers as necessary for a particular component. You can use standard OpenShift methods to manage the pods and balance the load.

Deployment to KIE Server

KIE Server is the server provided with Red Hat Decision Manager that runs the decision services, process applications, and other deployable assets from a packaged and deployed Red Hat Decision Manager project (KJAR file). These services are consumed at run time through an instantiated KIE container, or deployment unit. You can deploy and maintain deployment units in KIE Server using Business Central or using a headless Decision Manager controller with its associated REST API (considered a managed KIE Server instance). You can also deploy and maintain deployment units using the KIE Server REST API or Java client API from a standalone Maven project, an embedded Java application, or other custom environment (considered an unmanaged KIE Server instance).

Deployment to an embedded Java application

If you want to deploy Red Hat Decision Manager projects to your own Java virtual machine (JVM) environment, microservice, or application server, you can bundle the application resources in the project WAR files to create a deployment unit similar to a KIE container. You can also use the core KIE APIs (not KIE Server APIs) to configure a KIE scanner to periodically update KIE containers.
