Today, we are introducing Amazon EC2 Spot placement score in Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD to help you find the optimal location and instance type selection for your Spot workloads. Spot Instances availability varies depending on the instance type, time of day, and Availability Zone. Until now there was no way to find an optimal Availability Zone or combination of instance types to fulfill your Spot capacity needs without trying to launch Spot Instances first. Now, Spot placement score can recommend an Availability Zone based on your Spot capacity requirements. You can also test different instance type combinations to find the most optimal one for getting the capacity you need. Spot placement score is useful for workloads that are instance type and/or Availability Zone flexible.
To get started, go to the Spot placement score screen under the EC2 Spot Console. Simply specify the amount of Spot capacity you would like to request and what your instance type requirements are. For instance type requirements, you can either provide a list of instance types, or you can just specify the attributes your instances must have, like the number of vCPUs and amount of memory. You will receive a score for the whole Region or per Availability Zone on a scale from 1 to 10, based on factors such as the requested instance types, target capacity, historical and current Spot usage trends, and time of the request. The score reflects the likelihood of success when provisioning Spot capacity, with a 10 meaning that the request is highly likely to succeed. Please note that Spot placement score serves as a recommendation only and no score guarantees that your Spot request will be fully or partially fulfilled.
You can use Spot placement score through the EC2 Spot Console, Amazon CLI, or SDK. To learn more about Spot placement score see Spot placement score documentation. In addition to Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD, Spot Placement Score is also available in all other public Amazon Web Services Regions.
