The choice of going virtual or locking down on-premise depends on company-specific considerations, such as mission-critical workloads, security concerns, uptime requirements, or management demands. Services like virtual gateways and dedicated high-speed connections open up the option to provision a portion of existing data centers on premises, while extending capacity into the cloud for less sensitive computing loads.
A virtual private cloud offers hosted services to a limited number of people behind a firewall, minimizing the security concerns. Virtual private clouds also give companies direct control over their data and network access via routing configuration and security settings. Virtual private clouds deliver on the promises of utility computing, eliminating the concerns over wasteful over-provisioning while giving businesses confidence of never leaving customer demands unfulfilled during a surge.
