M/cluster delivers the robustness that you can rely on to build
mission-critical applications using the world's leading open source
database, MySQL. The product provides high availability services by
ensuring any number of MySQL database servers are fully in-synch at all
times. Fast and automatic failover ensures that any server can
transparently handle the queries from a failed or out-of-service node.
Load balancing ensures performance scalability. New nodes can be added
on-the-fly allowing you to add capacity without taking the system out of
service. m/cluster creates a single virtual database view of multiple
MySQL databases and is designed to integrate seamlessly with your
MySQL-based application. The architecture of m/cluster is designed to
use commodity hardware and does not require any special hardware devices
like storage area networks or load balancers.
