 The {aws} CDK is tightly integrated with {aws} CloudFormation. {aws} CloudFormation is a fully managed service that you can use to manage and provision your infrastructure on {aws}. With {aws} CloudFormation, you define your infrastructure in templates and deploy them to {aws} CloudFormation. The {aws} CloudFormation service then provisions your infrastructure according to the configuration defined in your templates.
 
-{aws} CloudFormation templates are __declarative__, meaning they declare the desired state or outcome of your infrastructure. Using JSON or YAML, you declare your {aws} infrastructure by defining {aws} _resources_ and __properties__. Resources represent the many services on {aws} and properties represent your desired configuration of those services. When you deploy your template to {aws} CloudFormation, your resources and their configured properties are provisioned as described on your template.

 With the {aws} CDK, you can manage your infrastructure __imperatively__, using general-purpose programming languages. Instead of just defining a desired state declaratively, you can define the logic or sequence necessary to reach the desired state. For example, you can use `if` statements or conditional loops that determine how to reach a desired end state for your infrastructure.
