Fault Tolerance and High Availability

Updated on September 11, 2020

To ensure high availability, configure two application gateways to run on separate Pega nodes and respond to the same queries. The application gateways should share the rules used to process and respond to queries (for example, your customized ProcessTaggedFields activity).

The ICM router(s) can be configured to send queries to either or both Pega nodes.
