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.

People were moving from Solaris to Linux BEFORE Oracle bought Sun. I think the hardware was the main reason. People just weren't going to pay the premium for Sun hardware. Now people just want to avoid Oracle.

Indeed people where moving to Linux before Oracle bought Sun but that was mainly replacing EOL small SPARC systems used for networking with either Linux/X86 or networking appliances(most of which are Linux or BSD based). In the finance sector and especially with big merchant banks the cost of a good SPARC system is well worth it. Retraining your staff on the other hand costs money and running Linux on a three X86 server VMWare setup to get the same reliability than with one SPARC system is not money saved.

Solaris is a very advanced and mature system. Coupled with SPARC it's rock solid which in many ways is vastly more important. As I've mentioned before, the only system that competes with it in the big iron UNIX market is AIX on POWER.
