AWS CloudFormation facilitates the creation and provisioning of AWS infrastructure deployments reliably and repeatedly. It allows users to leverage various AWS products like Amazon EC2, Amazon Elastic Block Store, and Elastic Load Balancing to build scalable and cost-effective applications in the cloud.
With CloudFormation, users can define infrastructure as code using a template file, enabling the creation and deletion of a collection of resources as a single unit, known as a stack. This simplifies the management of AWS resources and eliminates the need to manually configure underlying infrastructure components.
