VMware (VMW, EMC) officially launches its vCloud Hybrid Service, which allows clients to pair on-premise workloads with a VMware-run public cloud infrastructure. VMware claims the service supports more than 90 OS', has high-availability options, and allows public and on-premise workloads to be jointly managed. VMware also says it will offer SAP software, including Hana, "as a subscription service on premise and in the cloud." vCloud Hybrid competes with Amazon Web Services, Microsoft's Azure (perhaps the most direct rival), and Rackspace's OpenStack offerings. ITWorld calls it "ideal for a significant set of enterprise applications," but adds it's "no Amazon killer," given AWS' focus on low cost and ease-of-use.
