Major Linux Deployments

bstadil writes: "In the early days of Linux' entry into the mainstream (late 1998) Slashdot covered interesting wins for the OS like Burlington Coat Factory. Maybe its time to do it again. Within 48 hours Linux has made two HUGE inroads that merits mentioning. The first is the announcement of Home Depot plannig 90.000 Cash Registers running linux and Telia in Scandinavia replacing 70 Sun servers + Solaris with one IBM mainframe running Linux. One machine serving 800,000 internet accounts." ZDNet has a few more details.

Even more of a win for IBM

[Mike Connell]

The best thing about this (from my point of view), is not Telia going with Linux, it's IBM selling a big chunk of machinery with Linux on it. As long as the deployment isn't a total distaster it'll be a real good thing both for linux (running on *big* systems), *and* for IBM, *selling* - for money using linux. Hopefully a few of these types of sales will help cement IBMs commitment to both linux and open source...

Win win win!

Mike.

Different images in an S/390 / z900 are separated from each other in hardware and the VM software. The only way to circumvent this would be to somehow gain access to the VM control programs. You can be damn sure that these folks will be air-gapping the console and admin systems from public networks. VM controls cannot be accessed from the systems VM runs, period. (IIRC, this restriction is enforced in hardware.) In addition, the images cannot access the resources (storage or memory) of each other unless explicitly configured to do so in VM. The restrictions are good enough that mainframes have been running the same OS architecture for decades and I do not recall a single security breach of this nature.
