IAM : AWS services not supported and tagging support

I often get the question of which services do not support IAM?  Some services and features do not support IAM and must use the AWS root account credentials:

• Vulnerability Scanning Coordination Form
• AWS Workspaces
• Visibility of all Data Pipelines
• Specific account management pages, such as account profile, AWS account security credentials, payment methods and management of consolidated billing 
• AWS DevPay 
• CloudFront keypair creation

A full list of supported services is here:
http://docs.aws.amazon.com/IAM/latest/UserGuide/Using_SpecificProducts.html

This page also provides a great list of IAM resource level permissions support, tagging, and STS.

Tagging Oracle Database Instances

Instance tagging is a great way to manage and monitor instances.  It is also the way to do departmental billing and now with EC2 IAM resource level permissions a method to control the actions users and groups can perform on EC2 instances (more here: http://aws.amazon.com/about-aws/whats-new/2013/07/08/announcing-resource-permissions-for-amazon-ec2-and-amazon-rds/)

Placing tags on EC2 instances is this easy:
aws ec2 create-tags --resources i-f0ef69c6 --tags "Key=Cost Center,Value=AWS"
aws ec2 create-tags --resources i-f0ef69c6 --tags "Key=tier,Value=database"
aws ec2 create-tags --resources i-f0ef69c6 --tags "Key=environment,Value=test"
aws ec2 create-tags --resources i-f0ef69c6 --tags "Key=email,Value=thomas.laszewski@gmail.com"

To view all instances (and the value) with the cost center tag issue the following command:

aws ec2 describe-tags --filters "Name=key,Values=Cost Center"

Most monitoring and billing tools (CloudHealth, Cloudcheckr etc) use tagging to manage, monitor, and report costs and usage.

AWS resource tagging

Tagging of resources is great for billing and managing your resources. You also need to be aware of the EC2 and networking services and resources that do not support tagging:
