Database tier architecture

Pega 7 Platform high availability is database-agnostic. The recommended database features are:

Highly available clustered databases or third party or database vendor software that supports this feature
Database fault tolerance that meets production service level agreement requirements — for example, some databases have add-on products to handle failover of hardware or software sub-systems, enabling another piece to take over

For supported database platform versions, see the Platform Support Guide on the PDN.
