Which AWS service helps automate the infrastructure setup process?

AWS CloudFormation is the service designed specifically to automate the infrastructure setup process. It allows users to define their cloud resources and dependencies in a declarative JSON or YAML template. This template serves as a blueprint for the entire infrastructure, enabling users to provision and manage their resources consistently and safely.

With CloudFormation, you can set up a wide array of AWS resources like EC2 instances, S3 buckets, RDS databases, and more, all defined in one place. The service provides the ability to create and manage stacks, which are collections of resources that can be treated as a single unit. CloudFormation also supports versioning of templates, enabling you to track changes and roll back when necessary, which enhances reliability and repeatability during the infrastructure deployment process.

Using CloudFormation streamlines operations by eliminating manual configuration and minimizing the potential for human error, thus improving efficiency and reducing setup time for complex environments.

While other services listed play important roles in application deployment and infrastructure management, they do not specifically focus on automating the infrastructure setup process in the comprehensive and declarative manner that CloudFormation does. For instance, AWS Lambda is primarily for running code in response to events, AWS CodeDeploy automates application deployments, and AWS Elastic Beanstalk simplifies application deployment
