    How this can be achieved? Add a middleware virtualisation layer that helps the application take advantage of these new dynamically added resources. The article also describes in detail how to add auto-scaling to your existing application, including a description how to try it out on GigaSpaces XAP which uses EC2.

  • Here's a list of criteria when selecting a SOA testing tool.

  • A nice introduction to Hibernate's second-level cache.

  • Five tips for successfully deploying Maven. Including a bunch of pros and cons in the comments.
