ARN stands for Amazon Resource Name, and is a unique identifier used by Amazon Web Services (AWS) to identify resources. ARNs are used in various situations, such as when creating IAM policies, assigning roles to services, or passing role information to Lambda functions.
What is ARN in AWS?
An ARN is a unique identifier that represents an AWS resource. ARNs are used in many ways, such as to identify resources when creating IAM policies, assigning roles to AWS services, or passing role information to Lambda functions. You might also see ARNs in the AWS Management Console, for example, when you create an Amazon S3 bucket.
ARNs are composed of two parts: a type and a resource ID. The type is always arn , and the resource ID is specific to the type of resource.
For example, the following ARN represents an Amazon S3 bucket:
arn:aws:s3:::mybucket
The resource ID for an Amazon S3 bucket is the name of the bucket.
To learn more about ARNs and how to use them, see Working with AWS Identity and Access Management Policies.
IAM policies are used to grant permissions to AWS resources. An IAM policy is a JSON document that specifies the permissions that are granted to an entity, such as a user, group, or role. The policy also includes the resources that the entity is allowed to access and the actions that can be performed on those resources.
How do I get started with ARN?
If you’re new to using ARN, the best way to get started is to read the documentation on Working with AWS Identity and Access Management Policies. This will give you a good understanding of how ARNs work and how to use them in your own applications.
Once you’re familiar with the basics, you can start using ARN in your own applications. For example, you can create an IAM policy that grants permissions to a specific Amazon S3 bucket, or you can specify a role for an AWS Lambda function.
