Chapter 1. Overview of Red Hat Decision Manager on Red Hat OpenShift Container Platform

Decision Server, also known as Execution Server or KIE Server, is the infrastructure element that runs decision services and other deployable assets (collectively referred to as services) . All logic of the services runs on execution servers.

You can freely scale up a Decision Server pod, providing as many copies as necessary, running on the same host or different hosts. As you scale a pod up or down, all its copies run the same services. OpenShift provides load balancing and a request can be handled by any of the pods.

You can deploy a separate Decision Server pod to run a different group of services. That pod can also be scaled up or down. You can have as many separate replicated Decision Server pods as necessary.

Business Central is a web-based interactive environment for authoring services. It also provides a management console. You can use Business Central to develop services and deploy them to Decision Servers.

Business Central is a centralized application. However, you can configure it for high availability, where multiple pods run and share the same data.

Business Central includes a Git repository that holds the source for the services that you develop on it. It also includes a built-in Maven repository. Depending on configuration, Business Central can place the compiled services (KJAR files) into the built-in Maven repository or (if configured) into an external Maven repository.
