Abstract:
The Resin J2EE application server powers SalesForce.com. Both the open source version of Resin and ResinPro are ideally suited to complete the platform needed to host Java and PHP applications in the Amazon Web Services Cloud.

The latest version of Resin adds improved clustering capabilities that can take fuller advantage of the AWS environment in terms of load management and load balancing.

Resin is also adding a distributed cache (a simple Map) that is highly persistent and redundant. In the AWS environment, the cache can rely on either S3 or EBS storage. This is usable now, and lays the foundation for being able to perform joins.

Resin also provide an integrated web-server with dynamic page caching, eliminating the need for a separate Apache instance.

The full complement of the administration and monitoring tools provided with Resin continue to be available.

In many of the discussions on Cloud Computing, the capabilities and suitability of application servers are overlooked. With Resin, users can provide a rich SaaS offering on a cloud that they control.
