Which of the following is NOT one of the main ways to interact with AWS services?

• AWS Management Console

• Software Development Kit (SDK)

• Cloud Development Kit (CDK)

• AWS CLI

Answer explanation

Cloud Development Kit (CDK) is actually an infrastructure-as-code similar to the Terraform that we use. While it is used to define resources as code, it doesn't allow us to interact with AWS services like the other options provided above. For example, we can leverage SDKs to define API calls programmatically that upload images to S3 OR we also presently use the AWS CLI in our pipeline to upload our application code to S3. Similarly, the AWS Management Console is used for manual interactions with all services provided by AWS.
