public class Resource
Constructs a new AWS access control policy resource. Resources are typically specified as Amazon Resource Names (ARNs).
You specify the resource using the following Amazon Resource Name (ARN) format: arn:aws:<vendor>:<region>:<namespace>:<relative-id>
For example, an Amazon SQS queue might be addressed with the following ARN: arn:aws:sqs:us-east-1:987654321000:MyQueue
Some resources may not use every field in an ARN. For example, resources in Amazon S3 are global, so they omit the region field: arn:aws:s3:::bucket/*
