Chapter 1. Installation environment options for Red Hat Process Automation Manager
With Red Hat Process Automation Manager, you can set up a development environment to develop business applications, a runtime environment to run those applications to support decisions, or both.
- Development environment: Typically consists of one Business Central installation and at least one KIE Server installation. You can use Business Central to design decisions and other artifacts, and you can use KIE Server to execute and test the artifacts that you created.
- Runtime environment: Consists of one or more KIE Server instances with or without Business Central. Business Central has an embedded Process Automation Manager controller. If you install Business Central, use the Menu → Deploy → Execution servers page to create and maintain containers. If you want to automate KIE Server management without Business Central, you can use the headless Process Automation Manager controller.
You can also cluster both development and runtime environments. A clustered development or runtime environment consists of a unified group or cluster of two or more servers. The primary benefit of clustering Red Hat Process Automation Manager development environments is high availability and enhanced collaboration, while the primary benefit of clustering Red Hat Process Automation Manager runtime environments is high availability and load balancing. High availability decreases the chance of data loss when a single server fails. When a server fails, another server fills the gap by providing a copy of the data that was on the failed server. When the failed server comes online again, it resumes its place in the cluster.
Clustering of the runtime environment is currently supported on Red Hat JBoss EAP 7.3 and Red Hat OpenShift Container Platform only.
