Roles in AWS & their significance

With the continuation of my previous posts:

Roles are basically used for connect one AWS service to other AWS service.

Ex: S3 bucket to EC2 or viceversa.

1. Click on Roles option.in IAM pages.

Here in this post, i am just creating one simple role, Between S3 bucket and EC2.

2. Now click on Create role as shown below.

3.Now select the first service. Then click on Next permissions as shown below.                                                                                                                         

4.Now select the 2nd service called S3 here.and select the required policy. follow by click on Next.                                               

5. Provide custom role name & it should be unique to avoid confusion.and finally click on Create role button as show below.
