Cloud Bursting

Cloud bursting is an application deployment model in which an application runs in a private cloud or data center and bursts into a public cloud when the demand for computing capacity spikes. The advantage of such a hybrid cloud deployment is that an organization only pays for extra compute resources when they are needed.

If an enterprise has a VMware based internal data center, CloudSwitch allows the enterprise admin to seamlessly move the workloads to public clouds of choice — such as Amazon EC2, Rackspace, and the like. They do so by utilizing their “Cloud Isolation Technology” where they make the IP and MAC addresses of the public cloud appear as if they belong to an internal network. This allows the applications to run without any change when moved to public clouds and the workload can be brought back into the internal datacenter whenever the admin wishes. Another offering working to solve this problem is Amazon’s Virtual Private Cloud. It is different from CloudSwitch in the sense that it allows the corporate environment to connect the Amazon VPC via a VPN connection.
