VMware Continuent enables demanding enterprise customers to process billions of business-critical transactions using economical MySQL relational databases. Join us to learn how VMware Continuent adds high-availability, disaster recovery, and real-time data warehouse loading to off-the-shelf MySQL operating in vCloud Air. We introduce vCloud Air basics, then do a deep dive into the VMware Continuent system architecture covering important issues like failover, zero-downtime maintenance, and load scaling. We will conclude with a demonstration of using VMware Continuent to implement disaster recovery between a typical on-prem environment and vCloud Air.
