What is the primary purpose of Amazon VPC?

The primary purpose of Amazon Virtual Private Cloud (VPC) is to enable users to provision a logically isolated section of the AWS Cloud. This unique capability allows users to define their own virtual network, including IP address ranges, subnets, route tables, and network gateways. By creating this isolated environment, users can gain complete control over their network configuration, including security settings and access to resources.

Amazon VPC facilitates the deployment of resources like Amazon EC2 instances, Amazon RDS databases, and other services within this controlled private network. This level of isolation enhances security and allows for a customized networking environment that can mimic traditional on-premises data centers while benefiting from the scalability and reliability of the AWS Cloud.

The other options pertain to functionalities that can be achieved using different AWS services but do not capture the core purpose of Amazon VPC in terms of providing a secure and isolated networking environment within the AWS infrastructure. Data storage, running machine learning models, and managing user permissions are important in their own right but do not directly represent the main function of VPC, which focuses on networking infrastructure and isolation.
