I plan to use a particular instance configuration for steady-state workflows over a long period of time. Should I purchase a matching Reserved Instance to lower my average hourly bill for this instance over the long term?

Reserved Instances can offer two benefits—they can reserve capacity for a particular instance configuration to your account over the term of the reservation, and they can lower your average hourly costs for that instance. For more detailed information, see Amazon EC2 Reserved Instances.

You can purchase Reserved Instances through the AWS Management Console by following the instructions at Purchasing and Using a Reserved Instance.
