Benioff: We’re still an Oracle shop, but not just an Oracle shop crm), in case you were wondering, is still a huge Oracle(s orcl) database shop and will be for the foreseeable future. In fact, it just signed a ten year enterprise license deal with the database giant, CEO Marc Benioff said Monday at the company’s Salesforce1 event in New York.

But, he added, that doesn’t mean it’s not using a ton of other stuff including, potentially, the open source Postgres database.

“We are a very good customer of Oracle, we built on the Oracle database initially and continue to use it, it’s an important part of our infrastructure but we are constantly looking at all our core technologies, not just Oracle. Are they still current, modern? How do we update and evolve it? We’ve brought in lots of new tech into our infra… that’s where all the Postgres stuff comes from,” he said.

What many people may not realize is that by virtue of its $2.5 billion acquisition of ExactTarget last year, is also now a big Microsoft(s msft) SQL Server shop., after all, is 15 years old — it’s no longer a startup and there are new technologies out there now that were not around back then.

“We have a lot of different pieces running and they’re constantly shifting. That’s the nature of building and running services,” Benioff told a group of reporters at the event.

And, as to whether is moving to OpenStack, as Rackspace’s founder and chairman Graham Weston  said a few weeks ago,  Benioff walked those comments back. Benioff had high words of praise for both Rackspace and Openstack  but with a big caveat.

“We have some of everything running in-house via our acquisitions but OpenStack is not core. I’m not sure how to do that. Maybe it’s a good idea — I love their vision and strategy … but it’ s not a near-term reality for us.”
