I want to make sure that an instance type in a particular Availability Zone is available when I need it. How do I purchase an Amazon Elastic Compute Cloud (Amazon EC2) Reserved Instance that does that?
By default, newly purchased Reserved Instances don't reserve capacity.
To purchase a Reserved Instance that reserves capacity for a specific Availability Zone, follow these steps:
- Open the Amazon EC2 console and then choose Reserved Instances.
- Choose Purchase Reserved Instances.
- In the purchasing menu, in the upper right, select the Only show offerings that reserve capacity box.
- Choose the desired instance characteristics from the drop-down menus.
- Choose Search.
A column for Availability Zone appears in the search results. These Reserved Instances reserve that capacity for your use in that Availability Zone.
