virtuals and containers

I have been using qemu and, increasingly, virtualbox to run various OS experiments.  I also run the OEM XP that came on my workstation in a virtualbox instance on that same workstation;  a demotion of sorts I suppose.  I run R/C aircraft training simulators on XP as it is much cheaper to hit RESTART than to rebuild aircraft.

In the last couple of years I’ve been hearing more about containers as a potentially lighter-weight solution to problems that might have been solved using virtualization before.

Still getting my head wrapped around the container model, but I started a couple of small test containers for running some CLI utilities (screen and mosh, as it happens).  I was reassured to see that adding a 2nd and 3rd Debian-based container required only a few bits of data pulled down to support the new utilities.  I think this is supposed to be a major feature but it’s always good to see something for oneself.

One thought on “virtuals and containers

  1. I learned a bit about containers and docker but haven’t had much opportunity to play with them yet. I like the concept for virtualization as a light weight replacement in situations where you don’t need a full VM.
