CloudFormation
AWS CloudFormation is an infrastructure-as-code service that allows developers to model and provision AWS resources using declarative templates in JSON or YAML format. It automates the deployment and management of cloud infrastructure, ensuring consistency and repeatability across environments. By defining resources in templates, users can create, update, and delete entire stacks of AWS resources as a single unit.
Developers should learn CloudFormation when working with AWS to automate infrastructure deployment, manage complex environments, and enforce compliance through version-controlled templates. It is essential for DevOps practices, enabling infrastructure as code for scalable and reliable cloud applications, such as deploying multi-tier web applications or managing microservices architectures.
