A virtual data center (vDC) is a pool of allocated cloud resources for building enterprise-level IT infrastructure. vDC resources include processors, RAM, disk space, and networks on which virtual machines are built.
vDC is used to be combined with the concept of cloud, or virtual infrastructure (IaaS). The infrastructure, which is built in a vDC is similar to the physical one in the local data center, but has several advantages: the ability to be rapidly scaled, reduction of capital expenditure on IT, the ability to deploy test environments, high crash tolerance and high availability. The virtual environment is managed through a web interface: the user can remotely create new VMs, change the network configuration, create backups, etc.
vDC is suitable for companies that plan to expand the capabilities of their local IT infrastructure or offload it, to test new software products, to migrate fully or partially to the cloud — for example, due to relocation or business expansion.
