Just pointing out that the 5 second boot time is better than a regular VPS. Which (combined with per second billing) makes this good for batch/cron oriented serverless functionality. But is too slow for "function as a service" type serverless where the end user is waiting for it to fire in a browser.

Boot time is better than a normal VM.

OVH servers you're lucky if you get it in 5 minutes, not 5 seconds.

AWS is more like 60 seconds

5 seconds boot + per-second billing is the killer feature.
