The Spot Instance advisor helps you determine pools with the least chance of interruption and provides the savings you get over on-demand rates. You should weigh your application’s tolerance for interruption and your cost saving goals when selecting a Spot instance. The lower your interruption rate, the longer your Spot instances are likely to run.

Tip: Deploying your application across many instance types will further enhance availability. Consider using Spot Fleet, which makes diversification across multiple instance types and availability zones easier.

We recommend starting with instance types having lower frequency of being interrupted and adding more instance types as you improve your application’s flexibility and fault tolerance. See the Best Practices section for more tips and tricks.

The average frequency of interruption across all Regions and instance types is avg_rate.
