VPC – Isolated network environment in the cloud.
A Virtual Private Cloud represents a logically isolated section of the cloud provider’s network. It allows users to create a private, secure network environment with complete control over IP address ranges, subnets, route tables, and network gateways. VPCs can span multiple availability zones within a region and can be connected to on-premises networks through VPN or dedicated connections. They support both IPv4 and IPv6 addressing and can be configured with public and private subnets. Security features include Network Access Control Lists (NACLs) and Security Groups. VPCs are fundamental to cloud architecture as they provide the networking foundation for deploying resources like EC2 instances, databases, and load balancers. They enable micro-segmentation of workloads and help maintain compliance with security requirements through network isolation.
