Virtual Host
Increasing efficiency through
server virtualization

grow, IT infrastructure managers are seeking ways to
utilize systems and assets more efficiently. The worldwide
initiative to conserve power due to rising energy costs and
environmental concerns, has been driving efforts such as
server virtualization.
Tata Communications’ Virtual Host solution is
managed, cloud-based service that leverages the
of server virtualization to help companies
