Oracle Public Cloud: An Open, Hybrid Cloud for Business Applications

At last weeks' Oracle Open World show, CEO Larry Ellison took the wraps off Oracle's public cloud platform and strategy aptly named "Oracle Public Cloud," a broad mix of platform-as-a-service (PaaS) and software-as-a-service (SaaS), and a potential competitor to Salesforce, Microsoft, and others.

Oracle Public CloudThe five components comprising Oracle's public cloud are Sun servers; Fusion Middleware, Oracle database; Oracle Enterprise Manager 12c; and Oracle's Fusion Applications. The Oracle Fusion CRM Cloud Service and Oracle's workforce management tools are already available, while the database and Java services, as well as a new business-focused social network, will be released "under controlled availability in the near future," Oracle says.

Oracle boasts the Public Cloud will provide "all the productivity of Java, without the IT," and "the Oracle database you love, now in the cloud."

Ellison tore into rival Salesforce.com, claiming Oracle will differentiate itself with industry standards and support for "full interoperability with other clouds and your data center on premise."

While Ellison aimed almost all of his barbs and rhetoric at Salesforce last week, Oracle has another big PaaS competitor out there: Microsoft. Windows Azure is Microsoft's PaaS play, with its .Net "glue" and System Center management components. Office 365, SQL Azure, Windows Intune and other Microsoft-cloud enabled apps (like Dynamics CRM Online) are its SaaS play. So far, none of Microsoft's cloud-enabled apps is running on Windows Azure; they're running in Microsoft datacenters but not hosted on Microsoft's own public-cloud platform.

"Beware of false clouds," Ellison warned. He went on to claim that Salesforce, maker of CRM tools and the Force.com PaaS, is a proprietary cloud while Oracle is "standards-based," due to its embrace of Java, BPEL, XML, SOA, Groovy and Web services. Oracle Fusion applications will run anywhere, including in the Oracle cloud, Amazon's cloud, or in a customer's data center, Ellison said. Salesforce, meanwhile, is "the ultimate vendor lock-in... stickier than a roach motel."

"It's easy to interconnect applications in our cloud to applications in the Amazon cloud, to applications in your data center, all using standards," says Ellison, who has a long history with Salesforce.
