When Tata Communications, the Indian telecommunications company, rolls out its infrastructure as a service cloud offering in America in the coming months, company officials want to claim differentiating features in the products. And one they're hoping to include is support for multiple hypervisors.

If you've ever stayed at the Trump International Hotel and Tower in Chicago, the Chancery Court Hotel in London or the Keio Plaza Hotel in Tokyo, then the Preferred Hotel Group handled your reservation, delivered technology-driven guest services and took care of a variety of other behind-the-scenes functions.

Some enterprise customers just aren't comfortable throwing their data into a public cloud environment, says Ellen Rubin, vice president of cloud products for Terremark, which is owned by Verizon.

Terremark is offering enterprises a new private cloud service that includes the option to burst onto a public cloud.

The wave started last year when Time Warner Cable, the telecommunications company serving much of the Eastern United States, spent $230 million to purchase NaviSite, a provider of cloud services for businesses.

VMware is buying a 5 percent stake in Terremark, a close partner that provides collocation and managed infrastructure services using VMware's virtualization software, Terremark said on Tuesday.
