Sun's Linux killer shows promise | The Register

Sun's Linux killer shows promise | The Register: "Solaris containers (aka 'zones') are also noteworthy. They're virtual environments a bit like BSD jails, only slicker. Each container looks and feels like an isolated, virtual instance of the kernel, yet when idle, one container will use about 0.5 per cent of system resources, and fifty idle containers use about five per cent. One can choose maximum amounts of processing power to assign to each one, and the system will automatically distribute unused resources up to that limit among containers assigned less, and return it according to demand. One logs in to a container just as one would log in to a regular system, and all processes are effectively isolated. A container brought down by a hostile application can be restarted in a few seconds, without any wider impact."


It's time to short RedHat. Well may be not quite yet but its worth watching.
Solaris is a far more accomplished OS than any flavour of Linux especially with the new features in Solaris like containers, Live Upgrade, DTrace and others.
According to the article above Solaris is not quite ready for the x86 world because of lack of drivers for many popular devices found in common x86 boxes.
So if Sun does address this, you should see RedHat and other vendors starting to suffer especially with all the other software you can obtain from Sun which is often bundled in with Sun boxes.

Another space to watch

Those new features would make Solaris on x86 kick ass for a web hosting company. The hardware and OS would be cheap, and you could give every web site on a machine its own container to run in. If the client does something dumb (starts a runaway process, exposes a security hole, fills up a disk, etc) it would only take out their own container, and not affect everyone else on that machine. You could also control how much CPU each client gets, and charge more to deliver more grunt etc. And clients could compile their own kernel with parameters set how they want them, run web servers other than Apache (e.g. Zope), install their own applications, etc. The hosting company could basically give them superuser access within their own container, and just provide a big red reset button for when they stuff it all up.

IBM developed something similar to this for their high-end servers (running OS/360?), and they thought they'd take the hosting provider marketplace by storm. Problem was, the hardware and software was way too expensive to make it worthwhile, when everyone else was running cheap Dell x86 servers and Red Hat.
