HP's cloud IaaS offering, called HP Public Cloud, uses KVM and is based on OpenStack. HP also sells cloud-enabled infrastructure services like the HP Enterprise Services Virtual Private Cloud.
Strengths: Gartner described HP's vision for interoperable public and private clouds built on its hardware, software and partner ecosystem as "ambitious and comprehensive." Other advantages include a large global sales force and marketing budget, Gartner said.
Cautions: HP launched its public cloud IaaS last December, so it's still pretty new to the game, Gartner said. There also is "limited interoperability" between HP's Public Cloud and private clouds based on HP CloudSystem.
"HP Public Cloud's inability to import VM images on a self-service basis means that customers cannot currently directly transfer workloads from their private cloud to HP Public Cloud, even if their private cloud is based on OpenStack," Gartner said in the report.
