Rackspace offers a fixed-size, paid-by-the-VM, Xen-virtualized public cloud IaaS, with optional managed services. It also offers storage via an integrated content delivery network with Akamai, Database-as-a-Service, and PaaS, Gartner said. As the founder of the open-source cloud management platform OpenStack, its Cloud Builders business provides commercial open-source support and professional services around it.
Strengths Gartner said the company's wide community of participating vendors makes it a key cloud infrastructure ecosystem, up against VMware, Microsoft and Amazon.
Caution: The future of OpenStack's emerging technology is uncertain. "OpenStack's evolution may not necessarily align closely with Rackspace's needs -- it is possible that OpenStack could be successful without it leading to Rackspace's success," Gartner said.
