Multi-Site, Multi-Master MySQL Databases Made Easy with Tungsten - Webinar 9/22

Cross-site databases are the next challenge facing today's MySQL-based businesses. Continuent Tungsten enables multi-master with an innovative new architecture called System of Record that avoids data conflicts, ensures sites are ready for quick failover, and uses hardware resources efficiently.

Watch this video from our 9/22/11 webcast to learn how Tungsten Enterprise enables System of Record with real-time data synchronization, cross-site failover, and automatic routing of SQL transactions between sites. We will cover the following topics:
  • What is System of Record and how does Tungsten Enterprise use it to enable multi-site data management
  • How do you set up multiple sites with Tungsten
  • How do you failover between sites
  • How does Tungsten route transactions transparently between sites?
