AWS services that support Reserved capacity

Question

What are the list of all AWS Services that offer Reserved capacity and in turn provide significant discounts on the service

Answer 1

There's no official reference aside from the pricing pages for each individual service.

Some that I know:

• Amazon EC2
• Amazon RDS
• Amazon Redshift
• Amazon ElastiCache

Also, services that use Amazon EC2 can benefit from Amazon EC2 reserved instances. For example, Amazon Elastic MapReduce (EMR) uses EC2 instances, and will use existing EC2 reserved instances.
