What is the primary purpose of AWS CloudFormation?

The primary purpose of AWS CloudFormation is to automate the setup and management of AWS infrastructure using templates. CloudFormation allows users to define their desired infrastructure as code in the form of JSON or YAML templates. This capability facilitates the rapid deployment and management of resources through a declarative approach, enabling users to consistently set up and manage complex environments in a repeatable manner.

By creating infrastructure in a template, users can not only spin up resources quickly but also ensure that they are configured consistently across different environments. Additionally, the ability to update and delete resources according to the template streamlines operations and enhances efficiency.

The other options focus on specific services rather than the overarching capability of CloudFormation. For instance, managed database services are provided by Amazon RDS, hosting static websites utilizes services like Amazon S3, and delivering content globally is achieved through Amazon CloudFront. Thus, these alternatives do not align with the core functionality of CloudFormation, which is fundamentally about infrastructure automation and management.
