I want to purchase a Reserved Instance that reserves capacity for an Availability Zone.

Resolution

By default, newly purchased Reserved Instances (RI) don't reserve capacity.

To purchase a RI that reserves capacity for a specific Availability Zone, do the following:

  1. Open the Amazon Elastic Compute Cloud (Amazon EC2) console.
  2. Choose Instances from the navigation pane, then choose Reserved Instances.
  3. Choose Purchase Reserved Instances.
  4. In the purchasing menu, turn on Only show offerings that reserve capacity.
  5. From Availability Zone, select the zone that you want to purchase an Amazon EC2 Reserved Instance in.
  6. Choose Search.
  7. Review the Availability Zone column. Each RI listed reserves capacity for your use in that Availability Zone. Select the RI that matches the Availability Zone that you want.
