AWS Tutorial: IAM Roles For Instances (EC2)

Let's say you have an instance that needs to access an S3 bucket. You're doing machine learning on the instance and need to get data from the bucket. In this video, I explain how this works and how IAM roles are the most secure approach.

SUMMARY:
Configuring EC2 Access to Services:
-Option 1: Add IAM user credentials to the EC2 instance. This is not secure.
-option 2: Setup an IAM role with required access rights and give the EC2 instance access to it. This is a more secure approach. The EC2 will be able to access the necessary service. In this setup credentials are not stored on the instance.
