What is an Amazon VPC?

An Amazon VPC, or Virtual Private Cloud, is specifically designed as a virtual network dedicated to an AWS account, allowing users to define and control their network environment. This includes the ability to set IP address ranges, create subnets, and establish route tables and network gateways, which offers a high degree of customization and control over network settings.

Having a dedicated virtual network means that users can isolate their resources while still benefiting from the scalability and flexibility of AWS infrastructure. It enables you to host applications in a secure environment, while also facilitating specific configurations like private subnets for backend services and public subnets for web-facing components.

This focus on creating a secure, customized networking environment is what distinguishes Amazon VPC from other options. The other choices relate to different functionalities within AWS but do not accurately describe what VPC is or what it aims to accomplish in terms of network management and isolation.
