On the new RHEL server on AWS, there is no need to subscribe our own red-hat subscrition to install the package as it's already subscribed by AWS side. I need to know the difference between the AWS RHEL server's redhat subscription and normal redhat subscription. How the repo's are updating on AWS side(AWS redhat subscription). Are those repo's are trusty?
The official RHEL images in Amazon AWS are provided and maintained by Red Hat themselves.
Red Hat runs its own update infrastructure within every AWS region so that you can get official updates.
From the Frequently Asked Questions about RHEL on AWS:
Note that the names of the repositories differ when using RHUI in AWS, compared to using RHEL on-premise. Mostly they are the same with the addition of the string
rhui
. For instance instead ofrhel-7-server-rpms
the name would berhel-7-server-rhui-rpms
