The big news of the day at Oracle (News - Alert) OpenWorld yesterday may be the fact that Larry Ellison skipped out on his Tuesday keynote to participate in the America’s Cup boating event. (Monday’s race was limited to a single race due to light winds.) The CEO was replaced by Thomas Kurian, executive vice president of product development, who as a result gave his second keynote of the day on basically the same topic: Oracle’s cloud strategy and expanding product line.

To a quickly dwindling – but still respectable – audience, Kurian reiterated that Oracle Cloud delivers Customer Experience, Enterprise Resource Planning, Human Capital Management, and Social service suites. And that today more Oracle Cloud services are joining the family. New are Billing and Revenue Management Cloud, Business Intelligence Cloud, Compute Cloud, Database Cloud, Database Backup Cloud, Documents Cloud, Mobile Cloud, Java Cloud, Object Storage Cloud.

The company also opened for business its Cloud Marketplace, where Oracle partners can publish their applications and customers can access them. It includes more than 100 business applications developed by Oracle partners.

In an interview with TMCnet, Chris King, senior director of product marketing- communications industry at Oracle, explained that Oracle Billing and Revenue Management Cloud helps enterprises evolve from selling physical to digital goods by providing them with a subscription-based billing system. Billing, King added, is a relatively complex process, so this solution removes one of the key challenges in this customer transition.

Most organizations offering solutions on this front, King added, are startups, so they don’t have the depth of experience offered by Oracle, which already provides on-premises billing solutions for hundreds of customers.

“This represents a safe choice,” said King, adding that Oracle offers a proven solution and has the financial and human resources to support its customers.

He went on to say that customers using the new Oracle Billing and Revenue Management Cloud can bill on wide variety of metrics, including time, volume, or just about anything else.

While this solution was announced this week, it is not yet generally available, but is expected to be GA shortly, King said.

As for the other new Oracle Cloud solutions announced today, the Business Intelligence Cloud provide visual, interactive dashboards, available via the web and mobile devices, for administration, analysis, data loading, and modeling. Compute Cloud offers elastic compute capabilities to run any workload in the cloud. And Database Cloud lets customers spin up dedicated database instances as needed, and supports any Oracle Database application.

With Oracle’s Database as a Service, as Kurian referred to it, Oracle will fully manage that database instance for you. That means Oracle will back it up nightly, and deal with patching it and upgrading and tuning it if needed. And any software you use from Oracle in an on-site scenario will run exactly the same in this cloud environment, he added.

Meanwhile, Database Backup Cloud allows Oracle Databases to be backed up and replicated to the Oracle Cloud. Documents Cloud enables folks to do secure file sharing and collaboration via desktop and mobile devices. Java Cloud provides Oracle WebLogic Server clusters for deployment of Java applications and gives full administrative control over the service with automated backup, recovery, patching and high availability capabilities. Mobile Cloud lets businesses to build and secure any application to run on any device connected to any data source. And Object Storage Cloud offers a highly-available, redundant, and secure object store for lots of unstructured data.
