What is the significance of VPC in AWS?

1. It allows data analytics

2. It is used for application deployment

3. It provides an isolated segment of AWS infrastructure

4. It serves as a content delivery network

By subdividing your VPC into public and private subnets, you can control access to your resources and manage data flows effectively. This control significantly enhances the security posture of applications and services running in the cloud. While data analytics and application deployment can occur within a VPC, these are not its defining features. Furthermore, a VPC does not serve as a content delivery network, which is a different service within AWS designed for delivering content quickly and efficiently to users globally. The focus of a VPC is on creating a secure and isolated networking environment tailored to your specific requirements, making it fundamental for deploying applications in a manner that
