> If you want user to know they are talking to remote machine, but don't want them to care about which exact machine it is, we have a ton of great solutions already: load balancer, connection pools, service mesh, anycast, dynamic dns, etc... Those resources are complex to program against. An OS should offer a simplified abstraction layer to make them as transparent as possible. And yes, process management is worth having a unified programming model that doesn't force you to keep track of where each process instance is being located - that's essential for massively parallel computing. Of could this could be done with platforms for massively parallel computing. The point of building an OS would be to put these platforms as close to the metal as possible to improve their efficiency.
