A virtual private cloud is a little piece of your own IT real estate within the public cloud. With access via a VPN, you can build a bridge between your existing IT resources and your isolated infrastructure in the cloud, which can be secured with your existing firewall and intrusion detection systems, and configured with your own security and management policies. This way, you benefit from the best of both worlds: network isolation and secure connectivity as well as flexibility to add or decrease resources without the upfront costs of hardware and data centre.
