Core Lab Cluster is a solution that configures resources (databases, applications, etc.) operating in an x86 (Windows, Linux) environment
in an Active-Standby structure, and in the event of a failure, switches services to a Standby server and increases system availability to secure business continuity.
It supports a basic 1:1 (local replication or shared disk) configuration
and also supports an N:1 configuration depending on the environment.
Core Lab Cluster is Korea’s first high availability software developed
based on event detection.
