Middleware is an ideal area within your IT architecture to take advantage of the grid/cloud benefits of efficiency and flexibility. As the layer of infrastructure just below your applications and SOA services, middleware provides the right level of granularity of resources to be pooled and shared to enable desired control without undesired complexity.

In contrast to the traditional "stack" approach to middleware architecture, where, for example in the case of Java applications, each application runs on its own instance of an application server with it's own JVM on its own OS, an application grid infrastructure allows different resources at the application server level such as object memory to be shared, allocated, and dynamically adjusted across a set of application needs.

With the release of Amazon Machine Images pre-configured with Oracle Weblogic Server, it is possible to provision the best application server computing environment running on Amazon EC2 in a matter of minutes. Visit the Oracle AMI repository for a listing of all available Oracle AMIs.
