AWS Technical Essentials 2025 – 400 Free Practice Questions to Pass the Exam

The primary service used for automated resource deployment in AWS is AWS CloudFormation. This service enables users to define their cloud resources in a template format, often using JSON or YAML. By specifying the desired state of AWS resources in a CloudFormation template, users can automatically create, update, and manage related resources as a cohesive unit known as a stack.

CloudFormation simplifies infrastructure management by automating the setup process and ensuring consistency across deployments. Users can version control their infrastructure code, which enhances collaboration and simplifies team workflows. The ability to define complex environments through templates, while managing updates and rollbacks smoothly, makes AWS CloudFormation an integral tool for efficient resource management in the cloud.

While Amazon EC2, AWS Lambda, and Amazon RDS are crucial AWS services for compute resources and database management, they do not serve the primary purpose of automating the deployment of infrastructure resources on a broader scale like CloudFormation does. Instead, these services run instances, execute code, or manage databases within the framework established by configuration scripts or templates, rather than directly orchestrating the entire infrastructure deployment process.
