A Virtual Private Cloud (VPC) is a secure and isolated section of a public cloud, allowing users to create and manage their own virtualized resources. It combines the benefits of cloud computing, such as scalability and flexibility, with enhanced security features. Users can control their network settings, including IP addresses and subnets, to tailor the environment to their needs. VPCs are commonly used by businesses to host applications and store data while maintaining privacy and security. Major cloud service providers like Amazon Web Services and Google Cloud Platform offer VPC solutions, enabling organizations to leverage cloud technology without compromising on security.
