eXtremeDB HA is the fault-tolerant version of eXtremeDB that delivers 99.999% uptime through a primary-secondary architecture. eXtremeDB-HA replication assures the transactional integrity and consistency of secondary databases, and nearly instantaneous failover. Cluster implements a primary-primary architecture for applications that require distributed, cooperative computing and a resilient topology. Cluster supports distribution of all workloads (read- and write load balancing) on modest sized networks. All database operations are local; no replication occurs until a transaction is committed.
