Terracotta for Spring Answers Enterprise Demand for Open Source Framework with Drop-in Availability.

Interface21 and Terracotta Extend Collaboration to Support Clustering the JVM with Spring

SAN FRANCISCO -- Terracotta, Inc., a leader in delivering groundbreaking solutions for enterprise Java scalability, today announced the availability of Terracotta for Spring, arming developers with plug-in capacity, high availability and scalability for Spring applications with no additional infrastructure or code required. Terracotta for Spring is available for anonymous download at: http://www.terracottatech.com/downloads.jsp.

Spring is the leading Java application development framework, with well over one million downloads to date, and is driven by an active open source community. The increasing momentum behind Spring has made it the application framework of choice for many enterprises (seven out of ten of the leading investment banks having adopted it), which has led to growing demand for value added services around performance and availability.

"Spring provides a powerful, flexible component model that greatly simplifies enterprise development. This component model is an ideal basis for integration with other products and enterprise solutions, such as Terracotta's transparent clustering, that offer additional capabilities to developers without any requirement to modify their applications. The more transparent services Spring can bring to its developer community, the more Spring benefits users," said Rod Johnson, the father of Spring and CEO of Interface21.

Terracotta has already solved the issue of adding fault tolerance without code customization, which maintains the lightweight and flexible nature of the Spring Framework. The integration work has been completed, and the Spring community now has access to a non-disruptive, mature clustering solution. Terracotta for Spring is already being deployed by a large, multi-site construction company in the U.S.

Interface21 and Terracotta began collaboration in 2005. Since then, Interface21 has continued to invest heavily in Spring Framework development, and the companies have collaborated on developing integration between Spring and Terracotta technologies. With the explosive uptake of Spring, the companies have presented to standing room only crowds at events, such as JavaOne and Spring Experience, launched a Webinar series, and are now announcing extended, combined commercial support to include training, consulting, mentoring, and other services.

"Spring makes life easier for messaging, transactions, and domain modeling in general," said Ari Zilka, founder and CTO at Terracotta. "Terracotta helps take Spring's ability to simplify to the world of clustering. In a nutshell, Terracotta for Spring results in a simple, stateful, and clustered solution."

Product Information

Terracotta for Spring is a runtime environment for Spring-based applications that provides high-availability and high performance clustering.

Benefits of using Terracotta for Spring include:

* simplifies development and deployment cycles by shrinking source code

* distributes shared data without database load or abuse

* works with existing Spring applications

With Terracotta for Spring, developers can continue to create simple Spring applications, and those applications can scale out to multiple servers without the need for a database. Developers define which Spring application contexts they want to have clustered in the Spring configuration file. Spring applications are clustered automatically and transparently, and are guaranteed to have the same semantics across the cluster as on the single node. Java serialization is not required.

Key features of Terracotta for Spring include:

* clustering of Spring Beans, Events, JMX state and Spring WebFlows

* virtual memory for large, shared Java heaps

* flexible sharing and locking configurable at runtime

* cross-JVM Thread coordination (Wait / Notify)

* runtime visibility into the application cluster
