Linux When it comes to the fast-moving business of trading stocks, bonds and derivatives, the world's financial exchanges are finding an ally in Linux. As late as 2007, Wall Street exchanges were still largely run on Unix . . . Over the past few years however, Linux has crept into this market, showing up first in ancillary systems and then running a few core exchanges.

You can blame us for not having proper drivers for Linux...

But my point was not about what is better, my point is that Linux is a major competitor to AIX and zOS. Specially zOS, less so to AIX.

PS: They still get to pay those humongous license fees on mainframes. Since it does not matter what OS runs, licensing is done for hardware and clock cycles...

And that's the main reason why LoP is considered a bit of a joke.

I'm afraid that from where I'm standing, as in the actual implementation of LoP, that just isn't the case. As for the Mainfraim, it's only ever installed in an LPAR. In no way have I ever heard of zLinux being installed as the main OS. Correct me if I'm wrong but I don't think that's even possible.

I know about the licensing costs of the hardware and clock cycles but I'm not talking about the OS, I'm talking about the open source software that can be run on a Mainfraim dues to zLinux. Websphere for zOS costs way more to license than it does on open platforms.

zLinux can only be installed on an LPAR. But again, I coming from the trenches saying that Linux is a major competitor there. And I'm in the freaking deep end of the trenches for a long time now...

Webshpere for zOS is a very different beast compared to Websphere anywhere else*. But the cost of Webshpere is pretty much the same, if you consider what version is available for zOS and it's supplements. With Linux you can get a cheaper version of Websphere, but with less functionality. If you shoot for the same functionality, then the cost is similar.

*Just like DB2 on zOS has very little in common with DB2 LUW...
