Fly uses Firecracker, and they host long-running processes. I wonder what's their opinion about it.

>>wiradi+l2
I think their usecase makes a lot of sense as their workloads consume a predefined amount of ram. As a customer you rent a VM with a specified amount of memory so fly.io does not care about reclaiming it from a running VM.

Depends on if they're using smart memory allocation to keep costs lower, IE, if they can pattern that certain workloads only need N amount of memory at Y time, they can effectively borrow memory from one VM for usage in another that has an opposite statistical likelihood of needing that memory.

This is why paying for dedicated memory is often more expensive than its counter part, because that dedicated memory is not considered as part of pooling.

Shit like this is how you burn customers and then they find out you aren't changing the sheets, they change hotels.

Just because you can doesn't mean you should.

Almost everything is oversubscribed in our world.

Malloc will happily “return” the 15 TiB you asked for.

If 10000 people called 911 at the same time, only a tiny fraction would get through (and even fewer would get help).

Evacuating a large city by road would result in giant traffic jams.

There are 5-8x as many parking spots as there are cars (and we still can’t find a goddamn spot).

And of course… the great toilet paper shortage of 2020.
