Oracle (NASDAQ: ORCL) and Red Hat (NYSE: RHT) each are planning major cloud computing announcements on June 6. Best Guess: Oracle CEO Larry Ellison and President Mark Hurd will describe how all Oracle applications can run now run as a cloud service. Red Hat, meanwhile, will likely offer an update on the OpenShift (Platform as a Service) and/or CloudForms (Infrastructure as a Service) initiatives. And could there be a Red Hat SaaS surprise coming, too?

Both Oracle and Red Hat face plenty of questions in the cloud. Now, answers are emerging.

Updated, May 31, 8:32 a.m.: Ellison yesterday said all Oracle applications will be available via the cloud effective June 6. He made the statement during the D conference, hosted by The Wall Street Journal.

Meanwhile, Hurd recently said Oracle already generates more than $1 billion in annual SaaS revenues. Most of the major SaaS providers -- NetSuite and so on -- run Oracle's software as the foundation for their cloud services. And Oracle continues to crank up its own Oracle Public Cloud effort.

But Oracle Channel Chief Judson Althoff hasn't said much about how the Oracle PartnerNetwork (OPN) Specialized partner program will evolve to address the public cloud effort. Perhaps we'll get some answers June 6.
