Maybe "run-space" is more appropriate than "server". In the "old days" of the web, one could host many Perl or ASP-classic scripts (applications) on the same server without much problem (if you avoided risky practices). But with bigger stacks with more parts that need version management, we began moving to one-app-per-server. But that got expensive, so virtualization increased. Each app is now basically housed in one virtual server space such that it's not really a server in the original sense such that "run-space" seems a more fitting term. There are other competing terms such as "container", but that may be specific kind or brand. I'm looking for a more generic term.
