Continuent Tungsten: Proxies on Steroids for HA and Performance!

Big MySQL sites have long appreciated the power of database replication. However, replicated databases are complex to manage, don’t provide seamless availability, and require application changes to provide scaling benefits. We show how Continuent’s new Tungsten architecture rides new technology trends to create data services with high availability and performance using commodity hardware and off-the-shelf MySQL databases. Tungsten: remarkable for its robust properties, and it’s coming to open source!
