Virtual Private Cloud (VPC): A VPC is a logically isolated section of the AWS cloud that provides a private network environment for your resources. You control the IP address range, subnet creation, and configuration of route tables and network gateways.
Analogy: Imagine VPC as your own private office building within a city (AWS), where you control who has access and how they connect to the outside world.
Why It Matters: VPCs provide security and network isolation, enabling you to launch AWS resources in a virtual network that you define and control.
