AWS CloudFormation is specifically designed for automating the infrastructure provisioning process in Amazon Web Services (AWS). It enables users to define and provision AWS infrastructure using code through templates written in JSON or YAML. This approach allows for the management of resources as a cohesive stack, ensuring that infrastructure can be deployed consistently and repeatably.

With CloudFormation, users can create entire environments with a single command, making it easier to manage and orchestrate multiple resources across various services. It supports the creation, updating, and deletion of resources in a safe and controlled manner, often incorporating change sets that allow users to preview changes before applying them. This level of automation reduces the potential for human error and aligns with Infrastructure as Code (IaC) principles, vastly improving the deployment process.

AWS Batch, AWS Lambda, and AWS EC2 serve different purposes. AWS Batch is focused on executing batch computing workloads, while AWS Lambda enables serverless computing by running code in response to events. AWS EC2 provides scalable compute capacity but does not automatically provision infrastructure; rather, it allows users to launch and manage virtual servers. None of these services are primarily aimed at infrastructure automation like AWS CloudFormation.
