Is it a service, or is it a compiler?
It seems that the main differences are whether:
- the state is in some special form, or on the file system.
- the processing code is resident in a process
The two are related. Essentially, a service is a cached compiler: in
that it operates on an in-memory data store, using in-memory code.
These caches ar a real thing btw. Many environments take a long time
to load. (Essentially, compile or link themselves into existence.)
I wonder if there is a simple way in linux to snapshot an in-memory
state in a VM so it can restart very quickly.
