Amazon VPC

Amazon Virtual Private Cloud (Amazon VPC) is a foundational cloud networking service from Amazon Web Services (AWS) that lets users create scalable, isolated virtual networks within the AWS Cloud. Built for flexibility and robust security, VPC allows architects and developers to define their IP address range, create subnets, configure route tables and gateways, and control inbound and outbound connectivity. By closely mirroring traditional on‑premises network behavior inside the cloud, organizations can migrate or extend existing infrastructure with confidence while maintaining stringent traffic controls. One of its major strengths is enabling hybrid architectures: users can connect their VPCs securely to on‑premises networks via VPN or AWS Direct Connect, combine private and public subnets for multi‑tier applications, and use advanced features like peering, transit gateways, and flow logs for optimized performance and visibility. It integrates smoothly with other AWS services such as EC2 and RDS, making it a cornerstone for cloud deployments of all sizes. AWS’s global infrastructure means VPC customers can deploy resources close to their users for reliability and reduced latency.
