Elastic Capacity on Demand

Elastic Capacity on Demand (CoD) (formerly referred to as On/Off CoD) allows you to temporarily activate and deactivate processor cores and memory units to help meet the demands of business peaks. After you request that a number of processor cores or memory units are to be made temporarily available for a specified number of days, those processor cores and memory units are available immediately. You can start and stop requests for Elastic CoD, and you are billed for usage at the end of each quarter.

You can change the number of resources and number of days in a running Elastic CoD request. Instead of having to stop the current request and start a new request, or wait until the current request expires, you can change the number of resources and number of days in the current request. For more information about how billing works when changing a current request, or how to change a current request, see Billing when changing a running Elastic Capacity on Demand request or Changing a running Elastic Capacity on Demand request.

Make sure that you have prepared your server before continuing. For more information, see Preparing for Capacity on Demand.
