What Is Amazon Resource Name (ARN)?
AWS has many services and resources ranging from EC2 instances to S3 buckets, and you can have multiple instances for each resource. In a scenario where you need to identify a specific resource, it is only logical to have a unique ID for each resource. Well, there is, and it's called Amazon Resource Name (ARN).
In this article, you will understand ARNs and their significance within the Amazon Web Services (AWS) ecosystem. You'll get to dissect the structure of an ARN and how you can retrieve them. By the end of this article, identifying and deciphering ARNs will be a breeze for you.
An ARN is a unique identifier assigned to each resource in AWS. It is a string that's used to identify resources within the AWS ecosystem. ARNs identify resources such as Amazon EC2 instances, Amazon S3 buckets, IAM (Identity and Access Management) users, roles, policies, and others within AWS.
ARNs are required to specify a resource unambiguously across all of AWS. They are used in various AWS services and APIs to identify resources and grant permissions. This means that each resource can be identified uniquely regardless of the AWS region or AWS account it belongs to.
