Client MySQL: Beezz
"MySQL Cluster Carrier Grade Edition is a true carrier grade database, exactly what we need for our telco and enterprise clients. It gives us redundancy through the active-active replication with no single point of failure, high performance for maximum uptime, and full support from a world-class vendor. I don’t think there is any other solution even standing close to MySQL Cluster."
Denis Jdanov, CIO and Co-founder, Beezz
