Eucalyptus Session at Cloud Expo

Terracotta, the high-availability infrastructure software for Java apps, and Eucalyptus Systems, the open source private cloud platform, have joined up in the name of an open source solution that maximizes data scalability and application performance in a private cloud environment.

They'll tighten the integration between their widgetry and do joint sales and marketing.

Their combo is supposed to let large-scale enterprises provision private clouds on Eucalyptus' Amazon-compatible private cloud platform and capitalize on the cloud's elasticity, latency and flexibility.

See, enterprises adopting cloud architectures can face challenges related to the elastic provisioning of compute clouds on existing data center infrastructures; the data layer may not scale at the same rate as the compute layer. The Terracotta-Eucalyptus duo is supposed to - poof! - fix that.

Terracotta is supposed to let applications scale from a single server using industry-standard interfaces such as Ehcache to many nodes, even in highly virtualized environments such as private clouds by addressing the biggest bottleneck in deploying private clouds: relational databases that can't scale to meet the demand of the expanding application and are otherwise plainly ill-suited to cloud architectures.
