Fault-Tolerance with FTL Stores

As a storage mechanism, a quorum of FTL servers provides data persistence and replication features that support shared state fault-tolerance in EMS.

When using FTL stores, a fault-tolerant EMS server pair's configuration is stored in an FTL server cluster. This allows the configuration to be accessible to EMS servers running in separate machines or containers. Static configuration elements including JAAS modules, JAAS module configuration files, JACI modules and digital certificates are not stored in the cluster and must still be maintained manually.
