Securely managing authentication credentials is one of the first challenges that developers will face when

writing software that accesses Amazon Web Services (AWS). All requests to AWS must be cryptograph-

ically signed using credentials issued by AWS. For software that runs on Amazon Elastic Compute Cloud

(Amazon EC2) instances, developers must store these credentials in a way that keeps them secure but

also makes them accessible to the software, which needs them in order to make requests.

IAM roles for EC2 instances provides you with an effective way to manage credentials for AWS software

running on EC2 instances. With IAM roles, you can develop software and deploy it to an EC2 instance

without having to otherwise manage the credentials that the software is using.
