AWS SDK allows you to write code that interacts with AWS services. In this recipe, we will use AWS Java SDK for IAM to do some basic IAM operations to form a Lambda programmatically. We will use it along with Amazon CloudWatch and AWS CLI, which is a general practice followed in most real-world projects.
The aim of this recipe is to understand the use of AWS Java SDK inside Lambda. Therefore, we will not go deep into the details of the IAM operations discussed in the recipe. The IAM operations details are available at https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/examples-iam-users.html.
