AWS provides the root or system privileges only for a limited set of services, which includes
Elastic Cloud Compute (EC2)
Elastic MapReduce (EMR)
Elastic BeanStalk
Opswork
AWS does not provide root privileges for managed services like RDS, DynamoDB, S3, Glacier etc
For RDS, if you need Admin privileges or want to use features not enabled by RDS, you can go with the Database on EC2 approach.
Access Control Tags
Tags can be used as a condition in an access policy statement to control access to resources for e.g. Deny Delete Permission based on Tags
Resource Groups
A Resource Group is a collection of resources that share one or more tags.
Resource groups helps combine information for multiple resources and services on a single screen for e.g. for a Dev Tag there might be multiple resources for ELB, EC2 and RDS. Using Resource Groups all the resources and their status can be views on a single page
Tag Editor
Tag Editor allows addition of tags to multiple resources at once
Tag Editor allows searching of resources using tags and then add, edit, remove tags for these resources
