Ask HN: Why do you need container's fast boot speed?

[scprodigy]

Despite of the image and kuberentes, etc., let's talk about where the boot speed of container make sense.

For microservices and long-running jobs (build, db migration), does it really make a difference to launch the container in 1s or 30s or 100s?

It's fairly safe to say that, in computing, speed (in this case, a form of latency), always makes a difference to someone.

In a cloud environment, that latency could be wasted money in paying for an instance not doing work. Sure, it's averaged over that long-running time period, but in a continuous-deployment environment, that might not be all that long.

It can also have a very significant effect on MTTR in case of an outage, especially if multiple deployments are required.
