You'll explore how to test profile permissions from the AWS CLI and how to decode CLI messages using Security Token Services (STS), then you'll learn how to gather metadata about an EC2 instance with Instance Metadata Service (IMDS). Lastly, you'll discover how to install and configure AWS software development kits (SDKs) and how to integrate SDKs into software code to perform API calls against AWS services.
