Linux is ready for the ultimate challenge

If the London Stock Exchange can use Linux for its core trading system then surely enterprises can move to the open source version of Unix.

Trading venues are dependent on 100% up-time and high performance computing. Milliseconds of downtime can cost its customers millions and cause reputational damage.

This is why the London Stock Exchange is currently moving its Tradelect core trading system Tradelect, which was built using Microsoft .Net, to MillenniumIT’s core trading platform which is Linux based.

Linux is often seen as lacking support and large enterprises often overlook it.

But MillenniumIT started building its applications in Linux in 2006, when according to CEO Tony Weeresinghe, the developer wanted to bring the cost of its platform down.

So basically the London Stock Exchange, which is 100% dependent on the performance of its trading systems, trusts Linux.

Mind you it did buy the supplier in the process of deciding on moving to the new platform.

Weeresinghe says there are now two strong vendors in the market in the form of Suse Linux and Red Hat that enterprises can buy from. “They both offer good support.”

"So basically the London Stock Exchange, which is 100% dependent on the performance if its trading systems, trusts Linux."

you put 'if' instead of 'of'

and secondly (and most importantly! >:( )

its Suse Linux, not Susie!!

Actually, Linux has been meeting similar challenges of scalability, performance and reliability for some time now e.g. Google's servers are based on Linux (although their staff always seem to use Macs for their so-cool-it-hurts public presentations...).

The NYSE also uses Linux. It has been functioning in that capacity for some time now. The US Postal Service has also been using to sort mail since 1997, improving their mail sorting accuracy to 98%.


Thanks for your comment. Yes it is a good story for Linux that big companies that rely heavily on applications are building them in Linux.

The London Stock Exchange like other exchanges invest heavily in technology and it is good when they choose Linux.

The exchange's previous system was built in .Net and turned out as a bit of a disaster.

If an exchange can build its core trading platform using Linux then there are surely no limits. What do you think?


Thanks for the comment Frank

Where does the NYSE use Linux? Not its core trading platform is it?


There's a fair amount of work going on in the European public sector to make better use of open-source solutions including Linux. One of the most well-known examples is the city of Munich's Limux project:

The EU Open Source Observatory also has a summary of the project:

This has hit some problems in its timetable e.g.

But it's a pretty ambitious long-term strategic effort to shift the city's entire IT infrastructure over to Linux and open-source. Deputy head of the project Florian Schiessl has a recent blog entry discussing the current state of progress:

very nicely written article.. I am currently studying this at school and found it very helpful.

How do you think that speed is going to effect rankings? Personally I think that although it might not be a big factor now, it's going to get more important.

Just for those who are concerned about speed, you can speed up the loading speed of most sites (by up to 4 times) using 2 lines of code if your server supports zlib compression. Do a search for it and you'll see how easy it is.

It doesn't help with compressing css files though, you should Gzip those.
