Spot Instances are a cost-effective choice if you can be flexible about when your applications run and if your applications can be interrupted. For example, Spot Instances are well-suited for data analysis, batch jobs, background processing, and optional tasks

you can stop at any time without losing data.... with lambda, you need to run it 4 times to finish a job. i don't see how is that wrong ?

you can use all Spot Instances for any STATLESS, non-production application, such as development and test servers, where occasional downtime is acceptable.
