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.

Linux is killing

...Solaris in the banking industry here in Luxembourg. My next three contracts are Solaris to RHEL migration projects. But the reason isn't that Linux is better than Solaris, in fact quite the opposite. For the enterprise space, and especially the finance sector, Solaris eats Linux for breakfast! All those seamless RAS features you get with SPARC coupled with the tight integration of OS and hardware, even on X86, just makes Solaris the better UNIX. In fact Linux in the enterprise is a bit of a let down as it's such a moving target. I know that RHEL doesn't move as fast as Fedora but the features you get with Solaris (ZFS, easy management of Zones and DTrace) are vastly superior to the Linux offerings.

The reason everybody is jumping ship is purely political. Everybody hates the way Oracle treat their customers! The thing Oracle hasn't quite understood is that it's easier to migrate OS than it is to migrate DB; They don't have the same strangle hold, in the form of lock in, in the OS space than they do in the DB space.

I was talking to a 20 year Solaris admin just last week and he's disgusted with his employer's migration. He compares the current level of tech in Linux with Solaris 2.6. As we are now on Solaris 10 update 9 and edging towards Solaris 11, I can see his point.

I'm sure that for trading apps Linux is great but in the end, with Solaris you only needed to know one tech well to do your job and that was Solaris. With Linux, you need to have a deeper understanding of other technologies like VMWare and high end SAN arrays to get the same standard of RAS capabilities as you do with Solaris.

Sure, Linux will catch up I'm sure but it's still a step backwards for many sys admins. More shame to you Oracle!
