Red Hat's Continuous Kernel Integration (CKI) project provides CI-as-a-service
for all internal kernel development. AWS spot instances are used to provide the
computing power behind it.

Towards the end of 2022, the CKI project faced increasing issues with unstable
infrastructure because of its use of spot instances. Requested spot instance
types were either not available at all, or instances got terminated forcefully
shortly after launch. This prompted an investigation into the underlying issues
and ways to fix them.

This talk is going to tell the story of that investigation.

We will also discuss
- the limits of the Elastic Cloud of a Hyperscaler
- the various API calls to launch AWS spot instances
- the best way to do it, and things to be aware of

Attending this talk will leave you with deeper understanding of spot instances.
It should also convince you that reworking your code to use the newer API
calls is totally worth the effort.
