Taking a page from Microsoft's playbook, Oracle now has a way to extend its cloud into an enterprise's data center.

Cleverly named "Oracle Cloud at Customer," the subscription-based offering was launched today at Oracle's CloudWorld conference in Washington, D.C.

It's similar to Microsoft Azure Stack, which became available in January as a technical preview. Software called Cloud Machine lets developers write applications that can run on-premises or in Oracle's cloud. Ideally, this allows for a mix of both — a hybrid cloud with the same environment on the private and public sides.

Of course, with Azure Stack, that "environment" would be Microsoft's rather than Oracle's. As a result, a bit of a conflict could be emerging, where multiple cloud providers are reaching into the private cloud in ways that aren't necessarily compatible.

Tools available for Oracle Cloud Machine will include the company's Java Cloud Service and Integration Cloud Service to begin with. Support for Oracle's databases and for containers — Oracle is pitching the latter as a means of supporting non-Oracle applications — will be available soon, according to the company's blog post today.
