How do I check my eligibility for Reserved Instances?

You can check your eligibility by logging into the AWS Management Console, navigating to the EC2 dashboard, and looking for the Reserved Instances section. There, you can see available options and your account's eligibility.

Are there any specific requirements I need to meet?

Can I change my Reserved Instances after purchasing?
