AWS CloudFormation
AWS CloudFormation is an infrastructure-as-code (IaC) service that allows developers to model and provision AWS resources using declarative templates in JSON or YAML format. It automates the creation, updating, and deletion of cloud infrastructure stacks, ensuring consistency and repeatability across environments. This service helps manage dependencies between resources and supports version control for infrastructure changes.
Developers should use AWS CloudFormation when deploying and managing complex AWS environments, as it reduces manual errors and enables infrastructure automation for scalable applications. It is particularly useful for DevOps teams implementing continuous integration and deployment (CI/CD) pipelines, disaster recovery setups, and multi-region deployments, where reproducible infrastructure is critical.
