AWS CloudFormation is a service that allows organizations to model and provision their infrastructure as code in a safe, repeatable manner. This means that you can create and manage a collection of related AWS resources, providing a reliable way to set up and configure them according to your specifications.

With AWS CloudFormation, you define your infrastructure in a declarative manner using templates written in JSON or YAML. This enables you to describe the desired state of your resources, including servers, databases, and networking settings, while CloudFormation takes care of provisioning and configuring those resources in the correct order. As a result, it promotes automation and consistency across environments, reducing the manual effort involved in deploying resources.

In contrast, automating network setup, deploying applications on-premises, and managing costs associated with cloud resources do not directly represent the primary functionality of AWS CloudFormation. While it can be part of broader strategies that involve these aspects, its core capability lies in its ability to structure and provision AWS resources using infrastructure as code principles.
