Templates are the lifeblood of AWS CloudFormation. Written in either JSON or YAML, these text files define your cloud environment’s resources and configuration. Think of templates as a blueprint for your AWS infrastructure, guiding AWS CloudFormation in creating, updating, and deleting resources in your cloud environment.

By leveraging templates, you can manage your entire AWS infrastructure or specific AWS resources in a streamlined and organized manner. Template attributes also enable additional control and establishment of relationships between templates by adding to a single resource definition.

Stacks and StackSets

In AWS CloudFormation, stacks are collections of resources managed together and defined by templates. Stacks enable you to create, update, and delete stacks of resources in your cloud environment synchronized, ensuring proper resource management and configuration.

On the other hand, stack sets provide a means of deploying stacks across multiple accounts and regions, allowing you to extend your AWS infrastructure beyond the confines of a single account or region. With stack sets, you can easily deploy the same stack to multiple regions and accounts in a single operation, enhancing scalability and redundancy.

The DependsOn attribute in AWS CloudFormation defines the sequence of resource creation, ensuring resources are created in the correct order.

Parameters, Conditions, and Mappings

Customization is key to AWS CloudFormation templates, and that’s where parameters, conditions, and mappings come into play. Parameters allow you to define custom settings for each deployment, tailoring the stack to your specific requirements. Conditions enable you to define rules that govern the deployment process, ensuring resources are created only when certain conditions are met.

Conversely, Mappings allow you to map keys to corresponding values or obtain discounts using the intrinsic function “Fn::FindInMap”. Utilizing these versatile features allows you to create highly customizable and reusable CloudFormation templates that cater to your unique cloud management needs.

Change Sets and Transforms

Change is inevitable, but managing change effectively is crucial for AWS CloudFormation. Change sets provide a summary of the changes a revised template will apply before making the change, allowing you to preview and assess the impact of modifications before they are implemented.
