So VMware is not afraid of the public cloud after all. With the announcement of a forthcoming (later in 2013) VMware vCloud Hybrid Service, the virtualization leader reboots its cloud message for the enterprise. VMware will offer its own public cloud infrastructure service built on the same technology stack it offers to vCloud Datacenter service provider partners. That includes the vSphere foundation and the vCloud Director (with vCloud Connector) multi-tenancy and on-boarding tools, plus vCloud Networking and Security. VMware will add on a new public-focused portal and additional provisioning tools, and promises to share those capabilities with service providers as well, but it's not yet clear how and where VMware will differentiate and compete. If VMware offers better access controls and financial management tools, for example, than its partners, on the same platform, why would the partners not look to an open source alternative? That’s certainly a risk.
