undertakes read operations. This architecture is suitable for read-intensive types of applications, and read performance can grow linearly by increasing the number of Slave DB. To avoid a single point of failure in Master DB, the cluster typically uses two Master db for dual-machine hot standby, so the entire cluster has very high levels of read and write availability. In addition to providing Active Standby functionality from 11g, mysql,
