Oracle and amazon.com are teaming up to provide amazone's Elastic Compute Cloud customers more functionality. The Amazone Elastic Compute Cloud is a web-service provided by amazone.com which enables developers to create applications 'in the cloud', online a scale the running platform as they build. If you want to add more processor power, virtual memory or disk space to your application you can use the control panel to change the environment of your application.
Oracle announced that it will certify/support deployments of Oracle Database (all editions), Oracle Enterprise Linux, Oracle Enterprise Manager, and Oracle Fusion Middleware to Amazon Web Services' (AWS) Elastic Compute Cloud (EC2). In fact you may transfer your existing licenses to AWS if you like.
This will enable developers who where previously not able to use the amazone cloud, because they needed Oracle databases to run there program, to pick amazone as the platform of their choice. I found this new information on the weblog of justin kestely who is currently attending Oracle Open World.
