vCloud
vCloud is a cloud computing Platform made by VMware(EMC) which allows customers to migrate their working server on demand from their "internal cloud" of cooperating VMware hypervisors to a remote cloud of VMware hypervisors. The goal of the initiative is to provide the power of cloud computing with the flexibility allowed by virtualization.The initiative was announced at the 2008 VMworld conference in Las Vegas and garnered significant press attention.
At the 2009 VMworld conference in San Francisco vCloud was featured in the vCloud Pavilion. vCloud was also a subject at the 2010 conference. The vCloud initiative has grown with many public service providers and multiple supporting applications.
vCloud architecture relies on vShield edge for its operation, routed networks in vCloud needs a VM running vShield-edge software, acting as the default gateway of that network. This virtual gateway is implemented on a free host on the system and provides its services to VMs on that host and on other hosts.
vSphere
VMware vSphere is a platform for virtualization to transform datacenters into simplified cloud computing infrastructures and enables IT organizations to deliver flexible and reliable IT services. VMware vSphere virtualizes and aggregates the underlying physical hardware resources across multiple systems and provides pools of virtual resources to the datacenter.
As a cloud operating system, VMware vSphere manages large collections of infrastructure (such as CPUs, storage, and networking) as a seamless and dynamic operating environment, and also manages the complexity of a datacenter. The following component layers make up VMware vSphere:
