You can now inject random Amazon EC2 Spot Instance interruptions into your Spot Fleets directly from the Amazon EC2 console . In 2022, we launched the ability for you to use AWS Fault Injection Simulator (AWS FIS) in the Amazon EC2 console to simulate what happens when Amazon EC2 reclaims a single EC2 Spot Instance. Now, we have enhanced this capability so you can introduce interruptions in a randomly selected set of instances of a Spot Fleet with just a couple of clicks. This makes it easy to test if your Spot Fleet-based application is resilient against the random nature of Spot Interruptions.
