- The objects you work with on AWS. This includes buckets, domains, instances, queues, and so on.
- Tools, code, and documents that AWS provides to support users.
- An object that the principal requests access to. The resource is C in the statement "A has permission to do B to C where D applies."
- A required element of an AWS CloudFormation stack. Each stack contains at least one resource, such as an Auto Scaling LaunchConfiguration. All resources in a stack must be created successfully for the stack to be created.

A value required when including an AWS resource in an AWS CloudFormation stack. Each resource may have one or more properties associated with it. For example, an AWS::EC2::Instance resource may have a UserData property. In an AWS CloudFormation template, resources must declare a properties section, even if the resource has no properties.

Also known as Query or HTTP Query. This is a type of HTTP request that generally uses only the GET or POST HTTP method and a query string with parameters. Compare this with REST, which is a type of HTTP request that uses any HTTP method (GET, DELETE, POST, etc.), a resource, HTTP headers, and possibly a query string with parameters.
