Was hoping this comment would be here. Firecracker and microVMs are good use-case. Also, being able to simply test and develop is a nice to have.

Nested virtualization can mean a lot of things. Not just full VMs.

Good use-case for what?

We operate a postgres service on Firecracker. You can create as many databases as you want, and we memory-snapshot them after 5 seconds of inactivity, and spin them up again in 50ms when a query arrives.

Nowadays universal answer for "what? why?" is AI. AI agent needs VMs to run generated code in sandbox as they can not be trusted.

The poster you asked can reply too - Postgres and microvms are worth considering nearly every time at the start.

Beyond encapsulation it greatly increases the portability of the software between environments and different clouds.
