A virtual private cloud (VPC) is a unique option for any business to consider. It offers a lower cost than a private cloud while still offering customized options in security to meet the specific needs for data protection.
In the most basic terms, a virtual private cloud is a private cloud that is situated in the public cloud. It is separate and isolated from the public cloud. The VPC benefits from using the resources and hosting management services offered by the public cloud provider.
Having a virtual private cloud provides direct access to data and computing processes in the cloud by authorized users. Unlike a public cloud, where there is some competition for resources, a virtual private cloud locks in resources that are used only for the virtual private cloud tenant. No matter what the drain is on the public cloud, the resources available to the virtual private cloud users stay the same.
At the same time, a virtual private cloud is easy to scale. Should a company with a virtual private cloud need more resources, the third-party provider operating the public cloud makes the necessary allocations.
The Isolation Component
The virtual private cloud is isolated within the public cloud using a variety of different technologies. These include private IP addresses for the VPC that are inaccessible through the Internet and the public cloud.
Other security layers include a virtual private network or VPN. This offers full encryption specific to the virtual private cloud. A VLAN or virtual local area network adds a deeper level of partitioning to keep data private.
