VPC
A Virtual Private Cloud (VPC) is a logically isolated network within a public cloud provider, such as AWS, Google Cloud, or Azure, that allows users to launch resources in a defined virtual network. It provides control over IP address ranges, subnets, route tables, and network gateways, enabling secure and scalable cloud infrastructure. VPCs are fundamental for creating private, segmented environments in the cloud, similar to traditional on-premises networks.
Developers should learn VPC when building secure, multi-tier applications in the cloud, as it allows for network segmentation, isolation of resources, and compliance with security policies. It is essential for scenarios like hosting web servers in public subnets while keeping databases in private subnets, implementing VPN connections to on-premises data centers, or setting up hybrid cloud architectures. Mastery of VPC is crucial for roles in cloud engineering, DevOps, and infrastructure management.
