I believe so.

I don’t think either that or domain sockets are quite as ubiquitous as TCP sockets though.

The issue I see with domain sockets is that although they may be supported for example by spring, you can’t rely on a consistent cross platform experience which is perhaps (anachronistically?) a core ethic of the Java community.

I would favour domain sockets as to make a component go from being embedded to networked would require a small but significant implementation step.

But established best practice unfortunately disagrees with me.
