When we talk about user ids in AWS or any Cloud some [Non-AWS Practiced] people feel user ids of IAM and EC2s are the same. But not!

1. IAM user ids are made to access particular services of AWS Platform through some of the groups Privileges. These Groups are embeded with AWS policies to have access on the services.
2. Where as EC2 is a Virtual Machine [can be either Linux OS or Windows server]. It needs the users to access. Like your physical machines have the used ids, the VM also has them.
3. Watch the below video for details/discussion:

NOTE:

Contact for your real Cloud experiences learning and gaining with me and crack the interviews to get offers in AWS Roles globally or even you can transition to the role in the same company after facing the client interview/selection process. Which is very easy with this knowledge.

Please connect me on FB and have a discussion on your background and the needs/goals. I am looking for the serious learners only by having dedicated time. If you are a busy resource on the projects please note; you can wait to become free to learn. One need to spend time consistently on the practice. Otherwise its going to be in no-use.
