AWS Billing automatically applies your RI’s discounted rate when attributes of EC2 instance usage match attributes of an active RI.

Can apply to usage across all Availability Zones in an AWS region

Standard

 * Change Availability Zone, instance size (for Linux OS), networking type
    (Using ModifyReservedInstances API and console)

Convertible

 * Change instance families, operating system, tenancy, and payment option

RI Marketplace

Reserved Instance Marketplace allows other AWS customers to list their Standard RIs for sale.

Third-party Standard RIs are no different from the Standard Reserved Instances purchased directly from AWS

except they are often listed at lower prices and shorter terms.
