What AWS tool is used to create templates for service or application architectures?

The AWS CloudFormation template is a powerful tool used for creating templates for service or application architectures in the AWS environment. This service allows users to define the infrastructure needed for applications in a declarative way using JSON or YAML formats.

With CloudFormation, you can describe all the components of your architecture including EC2 instances, RDS databases, VPC configurations, and much more in a single template file. This means you can create, update, and manage your resources efficiently as you simply modify the template rather than manually configuring each resource through the AWS Management Console.

This automated approach not only enhances the consistency and reliability of infrastructure management but also supports version control, enabling teams to track changes to their environment as part of their codebase. Additionally, CloudFormation allows for easy replication of environments, which is invaluable for use cases like development, testing, and production workloads.

AWS Service Catalog, while useful for managing and provisioning catalogs of IT services, is not specifically designed for crafting templates of the architecture itself. AWS Config is primarily used for monitoring and assessing the compliance of AWS resources against desired configurations, not for creating architecture templates. AWS Lambda is a serverless compute service allowing you to run code in response to events, but it does not help in defining architecture
