AWS Certified Cloud Practitioner

AWS CloudFormation templates are used to automate the provisioning and management of AWS resources. They allow you to create, update, and delete infrastructure in a predictable and repeatable way, which significantly reduces provisioning time compared to manual processes. While CloudFormation helps manage infrastructure efficiently, it does not eliminate costs (option D is incorrect), transfer infrastructure to other companies (option B is incorrect), or directly reuse on-premises infrastructure (option C is incorrect). The primary benefit is automation-driven efficiency.
