Leader: Savvis
Savvis, owned by CenturyLink, is a longtime Web hoster, with a suite of public and private VMware-virtualized IaaS offerings with optional managed services, marketed under the Symphony brand.
Strenths: Savvis' multitiered IaaS product portfolio addresses a wide range of customer needs, and the company has a well-established track record of delivering enterprise cloud services.
Caution: Savvis' large and diverse product portfolio, with multiple types of single-tenant and multitenant IaaS, can be confusing. It offers many narrow point solutions, rather than creating a unified platform for a variety of solutions, according to Gartner.
