Setting up the components of highly available environments
Creating a highly available system typically requires coordination across multiple groups in an organization. Individuals or groups responsible for deploying highly available systems must collectively understand and agree on how to configure the Pega Platform for their organization.
The smallest environment for basic configuration testing requires the following:
- A load balancer
- Two instances of a web application platform of choice
- A database backend
- A shared disk for shared storage
Additionally, as a part of planning for future server maintenance, you must decide whether to use the default immeditate drain method or configure your system to instead use the slow drain method when you perform the quiesce process on a node.
