> Serverless

> A new slot configuration property which defines the resource allocation in terms of CPU and Memory, defaulting to c.125-m512 (.125 of a vCPU and 512MB of memory)

Sure sounds like needing to be concerned about the hardware. That feels like a leaky abstraction that the serverless design pattern claims or appears to take care of, but seems like it doesn't in practice. Is "serverless" the right level of abstraction? I'm not sure.

Whether it's serverless of not choice of hardware is very important.

For an simple web app, you might not need special CPU and Memory requirements. But for a video encoding/decoding serverless app may needs different CPU/Memory requirements (and GPU).

That's what this `slot` configuration property does.

The default is good enough for all the general purpose apps. But if you need more, you can control it.

I agree that one-size-fits-all doesn't work with hardware requirements, but I still think this is a leaky abstraction. The promise of Serverless is not having to care about servers, but this is an option to specifically control that. A better abstraction would auto-optimise hardware spec for the software's performance characteristics - that would be much more "serverless".
