Cyrill Troxler - Letting Your Containers Dream of Electric Sheep

If you have ever used Heroku, you might be familiar with a feature where your dyno will go to "sleep" when idle to save on resources. This raised the question, is there something that can do this on Kubernetes? There are some existing approaches, but none are that satisfy these requirements: * Workload agnostic — no code changes should be required on the application side. * Fast — users don't want to wait multiple seconds for their page to load. * Somewhat smart — the application should not go to sleep while it's being used. This talk will go over the problem at hand, existing solutions in the landscape and finally Cyrill will explain and demonstrate his approach live. In a nutshell, it's a Kubernetes runtime that snapshots whole containers to disk when no network traffic is coming in and restores in tens of milliseconds when a request hits.
