Supporting snapshot, pause/restore
odinho opened this issue · comments
Having the ability to snapshot and stop a running service would be great. Firecracker supports this.
It will allow massively over-provisioning on RAM, if you run super heavy instances that don't get a lot of traffic. All without writing hard code (just keep all your state in RAM).
Here's how Codesandbox uses it to fork a running VM in under 2 seconds: https://codesandbox.io/blog/how-we-clone-a-running-vm-in-2-seconds.
This new feature looks pretty cool.
