Virtual Private Cloud
A Virtual Private Cloud (VPC) is a secure, isolated virtual network environment within a public cloud infrastructure, such as AWS, Google Cloud, or Azure. It allows users to provision and manage resources like virtual machines, databases, and storage in a logically separated space with customizable IP addressing, subnets, routing, and security controls. VPCs enable organizations to extend their on-premises data centers to the cloud while maintaining privacy and control over network traffic.
Developers should learn and use VPCs when deploying applications in the cloud that require enhanced security, network isolation, and compliance with data governance policies, such as in finance, healthcare, or enterprise environments. It is essential for scenarios involving multi-tier architectures, hybrid cloud setups, or when needing to segment resources (e.g., separating development, staging, and production environments) to minimize risks and optimize performance.
