Oracle, Salesforce spar over cloud, multi-tenancy

At the center of the conflict in the cloud between Salesforce.com and Oracle is a technological discussion -- multi-tenancy versus virtualization.
Salesforce.com and the bulk of Software as a Service vendors plunge on the boundary of multi-tenancy -- an architecture where a solitary case of a programs request for paid job helps multiple customers.
“Multi-tenancy is truly the future of our industry,” Salesforce.com CEO Marc Benioff said in his off-campus keynote after his planned facade at OpenWorld 2011 was canceled. “We observe it in technologies that we all use every day -- Twitter, Facebook, Google, [Oracle CEO Larry Ellison’s] financial gathering NetSuite, our financial gathering Salesforce, Workday. All the new financial gatherings you’ve observed draw close along are all multi-tenant, divided architectures. It is the most recent, most prevailing of all architectures.”



Oracle is departing ahead with a divergent advance, one that admonishes multi-tenancy as unsafe and outdated. The development oversized is alternatively preferring a cloud virtualization type, where each user’s data would be put on a split database and run on a split virtual machine.
While multi-tenancy has advanced large reputation because it impressively lets down overhead and cost and can lessen carbon emissions, Larry Ellison disputed in his OpenWorld keynote speech that it sets enterprise written knowledge at risk.
“That’s a very horrid security type, to put everyone’s written knowledge in the matching database,” Ellison said. “It’s called multi-tenancy, and it was the state of the art 15 years in the past when [Salesforce] started. I intend, it truly was the best we could perform 15 years ago.
“They put your written knowledge at risk by comingling it with your competitor’s data.”
Benioff rejoined that multi-tenancy has a “tremendous past files of security,” and the back-and-forth engagement of thoughts carried on on. Benioff incisive to public broadcasting website Facebook as the greatest disagreement for multi-tenancy.
“Virtualization is not the pinnacle of efficiency; the pinnacle of competence is multi-tenancy, and the validation purpose is Facebook,” Benioff said. “What would it take to bring ahead that on a case-by-case foundation to all those customers?”
