IBM, HP, Cisco, and AT&T are the preferred infrastructure-as-a-service (IaaS) providers, topping the likes of Amazon Web Services, Microsoft, or Rackspace, according to a new IDC report on enterprise cloud computing.
In a key finding, the report says, “buyers selected IBM as their overall top preference among providers they believe can most effectively provision IaaS, whether private or public. Following IBM in the top spots were Cisco, HP, AT&T, and Google.”
The report, “U.S. Buyers Rank IBM, Cisco, HP, AT&T, and Google as Likely Most Effective Top 5 Providers in Delivering IaaS,” is IDC’s first Public Cloud Tracker report. It was authored by IDC analyst David Tapper. Tapper defined infrastructure-as-a-service as either shared, multi-tenant servers in the cloud (public IaaS) or dedicated servers in the cloud (private IaaS). Rackspace and IBM’s SoftLayer unit provide dedicated servers to customers who want greater isolation than multi-tenant servers allow.
