@hyc OS level containarization is a good thing, IMHO. But it shouldn't rely on pieces "attached". FreeBSD Jails and illumos Zones do this in the proper way.
@stefano I've always been disgusted with the proliferation of docker and containerization. Just insane.
At this point, application vendors should be shipping monolithic apps with statically linked libraries. No need for any further isolation from system dependencies.
"The contrast with Docker is striking: while the Docker container required 100% CPU to reach peak for the HTTP and HTTPS throughput, the FreeBSD jail delivered the same speed with ~60% of the CPU sitting idle. In terms of performance cost per request, Jails are drastically cheaper."
