What is the primary function of Amazon VPC?

The primary function of Amazon Virtual Private Cloud (VPC) is to allow users to launch AWS resources in a defined virtual network. This capability enables customers to create a logically isolated section of the AWS cloud where they can define and control their virtual networking environment, including IP address ranges, subnets, route tables, and network gateways. By using a VPC, organizations can securely connect their resources, control their traffic flow, and manage how their applications interact with the internet and other AWS services.

This defined virtual network not only provides enhanced security but also allows for better resource management and performance optimization. Users can configure their VPC to meet specific compliance and security requirements, tailoring their networking setup based on their unique requirements for different applications or services running on AWS.

Other options focus on different aspects of cloud functionality. For instance, creating Docker containers pertains to containerization and orchestration, which is served by services like Amazon ECS or EKS, running batch processing jobs relates to managing workloads, and managing serverless applications involves using AWS Lambda or similar services. These tasks do not encompass the fundamental purpose of VPC, which is centered around establishing a secure and customizable virtual network.
