In June this year Microsoft and Oracle announced an enterprise partnership allowing customers to run Oracle Software, including Java, Oracle Database and Oracle WebLogic Server on top of Windows Server Hyper-V and in Windows Azure and receive full support from Oracle.
Yesterday Microsoft announced that they added preview Windows Azure images of pre-configured virtual machine images running various combinations of Oracle Database, Oracle WebLogic Server, and Java Platform SE on Windows Server, with licenses for the Oracle software included.
During the preview, these images are offered for no additional charge beyond the regular compute costs. After the preview period ends, Oracle images will be billed based on the total number of minutes VMs run in a month; details on the VM pricing to be announced at a later date.
Oracle now also offers Oracle Linux, Oracle Linux with Oracle Database, and Oracle Linux with WebLogic Server in the Windows Azure image gallery for customers who are licensed to use these products.
