AWS CloudFormation provides a way for users to model an entire AWS infrastructure in a text file, allowing for the infrastructure to be version-controlled, shared, and reused. Resources are the AWS components that are created, updated, or deleted when the CloudFormation stack is created, updated, or deleted. Parameters enable users to input custom values to a CloudFormation template, allowing for customization without modifying the template itself. Mappings define a set of key-value pairs that can be used to map input values to corresponding output values, making it possible to conditionally define properties and values based on the input parameters. Conditions enable users to define conditional statements within a CloudFormation template, allowing for the creation or modification of resources based on specific criteria.

These conditions are evaluated based on input parameters that you declare when you create or update a stack. After you define all your conditions, you can associate them with resources or resource properties in the Resources and Outputs sections of a template. You define all conditions in the Conditions section of a template except for Fn::If conditions. You can use the Fn::If condition in the metadata attribute, update policy attribute, and property values in the Resources section and Outputs sections of a template. You might use conditions when you want to reuse a template that can create resources in different contexts, such as a test environment versus a production environment. In your template, you can add an EnvironmentType input parameter, which accepts either prod or test as inputs. For the production environment, you might include Amazon EC2 instances with certain capabilities; however, for the test environment, you want to use less capabilities to save costs.

AWS CloudFormation is a service that helps you model and set up your AWS resources so that you can spend less time managing those resources and more time focusing on your applications that run in AWS. You don't need to individually create and configure AWS resources and figure out what's dependent on what; CloudFormation handles that. The following scenarios demonstrate how CloudFormation can help. For a scalable web application that also includes a backend database, you might use an Auto Scaling group, an Elastic Load Balancing load balancer, and an Amazon Relational Database Service database instance. You might use each individual service to provision these resources and after you create the resources, you would have to configure them to work together. All these tasks can add complexity and time before you even get your application up and running. Instead, you can create a CloudFormation template or modify an existing one.
