NY Stock Exchange Moves To Linux
An anonymous reader writes "Even the old mainframe strongholds, the financial markets, are moving away from big iron. The New York Stock Exchange is one of them, as it's leaving the mainframe for AIX and Linux. They're doing it to save money; it seems that transactions are going to cost half as much on Unix and Linux as they did on the mainframe." The first phase of the transition happened last Monday.

Anyone reminded of that ad about the guys printing the newspaper that says they use Windows because its more reliable and stuff? That wasn't for the NYSE was it? I see that ad all the time on Slashdot and roll my eyes every time :-p
If you are about to mod me down, keep in mind that this post was most likely sarcastic.
The bulk of the savings seem to be coming from reduced hardware and maintenance costs by getting rid of the mainframe and the savings are the reason they are doing it.
Do not try to read the dupe, thats impossible. Instead, only try to realize the truth
What truth?
There is no dupe

What about stability issues? I'd think that these machines would have to be a little bit more robust than linux is capable of being at the moment.
Thats one small step for penguins, one giant leap for penguin kind. Now I can invest in Linux companies while I am doing it on a Linux machine and the transaction being processed by Linux :)

In my brief experience with an IBM AS/400 (before it was renamed), it seemed like my old company was paying as much annual licensing and support fees as the system originally cost. The software we ran got more expensive as the system went faster. I never quite understand that pricing scheme, since the software didn't actually do anything NEW.
Good move for the NYSE.

In case anyone needs to look it up, Linux is in Eastern Europe between Serbia and Romania.
Happy to help.
I think this is only the beginning of large migrations. To have both 3270 and Linux skills (along w/ DB2) right now would be a killer skills combo.
Well, the migration strategy seems interesting, although not especially surprising; they've eschewed emulation strategies that might incur a performance penalty in favor of some company that actually recompiles the old COBOL and IBM JCL code for modern architectures and does a lot of in-house QA (and, one assumes, has really good support...). They're using smaller IBM AIX servers to actually run the code in the new system, with the HP Linux machines basically doing all the I/O and general feeding of data.
I'm a little surprised that IBM didn't manage to sell them on a new mainframe, or at least on its own clustered solution; or that they didn't ditch IBM completely and go with somebody else (what I'd suspect if somehow someone at IBM had really stepped on the wrong foot).
There's not a whole lot of information in TFA about their old system, which actually sounds like it must be fairly neat; it's only described as a "1,600 MIPS mainframe" and then from context it's clear that it's an IBM of some sort. Another surprising thing is that they complain that the software licenses for it, among other things, are prohibitively expensive -- you'd think that IBM, in danger of losing a mainframe customer completely to commodity kit, would cut them some sort of a cheap-or-free deal on the software just to keep them around and on the support contracts. (I really gotta wonder if someone really boned this up; I mean, if you can't keep a mainframe contract at a place like the NYSE, really, what are you doing?)

Microsoft says New York Stock Exchange infringes on Microsoft's patent "Letter C in System". Microsoft broad patent invoking the use of the letter C on a file system has some industry experts worried. "We were completely unaware that Microsoft had the rights to the letter c on any operating system. This is going to cost us enormously. We thought we would save twice as much money, but with this frivolous lawsuit pending, we stand to lose four times as much" stated an anonymous expert at the NYSE." Microsoft's shared plummeted after an irrate Linux developer injected a logicbomb code on NYSE servers.

The article makes it sound like transactions are on a cost-per basis, "[Francis Feldman] estimates the move will halve the cost of transactions" -- does that make any sense?
I think the author of the article got into a tangent with him about how many transactions they do, and what their operating costs are and then incorrectly made the correlation that there is a cost-per-transaction from a computing stand-point. That can't be true. You don't insert fifties into the A: drive.
Look at it this way: If they make the big switch, and all of a sudden they can handle double-the-transactions per day - that would halve the cost of transactions. Only there's not going to all of a sudden be double-the-transactions. They're still working with the same number of transactions.
If they halve their staff, and they do the same number of transactions than that halves their costs. But what if tuesday is a slow day, and they only do 60% of their normal business? They're still paying for all the staff, electricity and third party support.
Am I wrong, or is it unlikely they can correlate a cost per transaction in this case?

Now that's service. I realize it's only compiling one code into another form but being able to take the code, compile it into what you need AND still have it work correctly in a 24 hour period is no easy feat.
If nothing else, other firms will look at this migration to an aix/linux platform and see the cost benefits of doing so. After all, if the NYSE has done it, it can't be a bad thing.
We will bankrupt ourselves in the vain search for absolute security. -- Dwight D. Eisenhower
Would anyone be surprised if the exchange captured most of those cost savings for themselves?
I think another post is onto something:
1. IBM screwed up the relationship so badly that the NYSE is walking away.
2. IBM has some other, greater, revenue opportunity.
3. Something is going on inside IBM where the sales people can steal each other's customers.

Unikix has been around since the early 90's. Moving gobs of COBOL II, JCL, and JES2/3 over has been done and redone. The real challenge is what to do with CICS? CICS code can be pretty damn hard to port with the same performance criteria. A well built CICS system can approach an RTOS in real time transaction performance. But the architectural complexity is a hard problem to solve in another system architecture. For instance one way to get CICS to fly is to run it as a continuous communications task in its own LPAR. I don't know how you do that in AIX which tends to be more queue driven. But maybe they solved that problem.
And for you who have a question about AIX, that's an IBM product too so are the servers it runs on. So from a cost perspective they're still paying IBM either way. I suspect also that they're running a UDB/DB2 back end database already which is why they're moving to AIX - DB2.
I was once involved in a migration from mainframe to a distributed architecture for a billing and invoice system that would process 4 million transaction in an 8 hour period. It didn't work well; even with the hottest *NIX boxes available. The mainframe's performance was that superior. That was in 2000. I will be real curious if they get it to work and I hope someone posts an article here on the results when the time comes. (I'll forget all about this by the time it's implemented - I'm getting old.)
I prefer Flambe as apposed flamebait.
transactions are going to cost half as much on Unix and Linux as they did on the mainframe

And I'm sure they'll pass those savings along to the consumer.

Actually, according to TFA they are doing most of the work on AIX with some Linux boxes on the front end for "ftp" data transfers.

the trades will be managed by aix and linux will just be used for "ftp transfers on the front end." this would be bulk data transfers, not data feeds and all i/o as other might have suggested. i can pretty much guarantee you that the nyse is not processing trades and sending out live market data (to bloomberg, retuters, etc.) by ftp.
also, i am somewhat concerned by this move in light of the trading disruption at the end of february where the existing (mainframe, i presume) trading systems could not handle all the trades and the data feeds were way behind the actual prices of the securities. i know the nyse is a public for-profit company now, so it's silly to talk about "public interest" but shouldn't there be some regulation about the capacity of their IT infrastructure to make sure that their cost-cutting doesn't cause another 4% decrease in stock market value on an abnormally high trading day?
"Transaction cost" is a common metric in the financial-processing world; rather than just talking about cost-per-quarter, they take the cost of the equipment and then divide it out by the number of transactions they process.
It's not the greatest metric in the world, but it does provide some ability to compare "efficiency" across systems. But it's a little misplaced in all but the most predictable workloads, because it's not like your operating costs are really going to fluctuate with the number of transactions you process that day. The system is basically going to cost the same amount regardless; if you process fewer transactions, the CPT just went up even though nothing on the systems side changed. But for someone like the NYSE where the overall number of transactions is predictable, it's probably not a bad way to compare options.
More on CPT. (Incidentally I think it was people looking to stabilize CPT that led to the interest a while back about 'metered computing,' where you'd outsource your IT stuff to someone and basically get a bill at the end of the month, and your bill really would reflect the workload that month, basically giving you a flat cost-per-transaction. Apparently this is very attractive to some people due to their accounting methods, although maybe not enough to sell them on it.)

They made a bad financial desicion.
Any savings they think they made in the hardware, licensing and support costs will be lost many times over as soon as the system makes a small error or goes down.
This is the reason why financial transactions still use mainframes.
Mainframes are unique in their integration and optimization between the hardware and the operating system they run. It gives you a level of performance, integrity and fault tolerance which cannot be achieved by taking generic hardware and sticking Linux on top.
They probably thought (ironically like the stockmarket does) that in the short term there is significant savings to be made switching the system to generic hardware and linux. In the long term however they will be faced with more expensive and frequent maintenance and upgrade cycles. Mainframes on the otherhand are scalable almost to infinity and you pay for the reliablity and maintenance upfront when you purchase the system.
What they could've done is buy a new mainframe and run their application level with virtualized Linuxes. After all this is what mainframes are good at.

It's funny you say that but I've been administrating Linux/AIX for a year and I just had 3 months of 3270 training. Now I support MF applications JCL/COBOL/EZTRIEVE and AIX/Linux applications/scripts/perl...... how much an I worth?
But then, if you run say RHEL 4 (2.6.9) or Slackware 10 on a nice piece of kit then you get AIX-like stability. It's when you use fancier, newer features (i.e. experimental filesystems) or more esoteric hardware that you can get yourself into trouble.
And even so, if they're clustering it then you'd expect they'd build in node failover and monitoring, so a hard freeze should trigger a watchdog and someone goes and kicks it in the head (if that isn't automated). And you log it, just in case a node is actually developing hardware failures.
We would assume they would test, test, test to identify the stable configurations before hand. It would be irresponsible to do otherwise.

I thought it was well-known that the mission critical NYSE back-end database ran HP NonStop hardware and software (formerly Tandem). The NYSE has lots of systems...I'm sure they are moving some stuff to x86 Linux, but I really doubt they are replacing the NonStop systems with Linux.
Actually, NASDAQ switched to Microsoft and SqlServer 2005 roughly 18 months ago. Nasdaq bills themselves as "the stock market for the next hundred years" -- I wonder how long they will stick with MS SQL Server?
No, you're still an idiot. They're charging per transaction. Therefore, the cost per transaction is what matters. Their costs from IBM were performance based, and the number of machines in their cluster will grow with the increase in volume, so the cost per transaction is still a very good metric. Learn a little about finance, slashtard.
IBM will support old hardware, they'll just charge you a fortune for the privilege.
I suspect that this "maintenance cost" is one of the reasons for the change mentioned in the article.
Move to commodity PCs, increase redundancy, profit!
No sig today...
I worked at a world-wide bank that ran its entire operations on a pair of ES/9000 mainframes from IBM and, while insanely expensive, requiring a full-time staff of 12 people (for each machine), requiring a separate floor on the building, etc. etc., I have still never seen anything that came close to the horsepower these things had. They simply wiped the floor with everything else out there.
... these people did not worry about efficiency for the most part simply because the machine was so fast, they didn't need to.
As an example, it calculated a person's balance by starting with their opening balance, then went down the vsam file, adding and subtracting amounts, till it reached the bottom and gave the total. This process was instantaneous, even given all the other things it was doing.
Sure there are better ways to do it, like storing the data in a real RDMS, using a trigger to update a "balance" field so it's a quick query instead of a lot of calculations, etc., but I wonder if so much of what we do is simply making the best of essentially a hardware deficiency; the baddest Intel-based Linux box probably couldn't do what this 20 year old mainframe can do, so we make it do the same thing but in different ways.
Working with the mainframe programmers, all Cobol folks, made me think always of that great Dilbert cartoon of the smug Unix guy giving Wally a nickel and saying "get yourself a real computer"
So ultimately it's too bad that mainframes, for all their horsepower, really do resemble, to a certain extent, the moniker "dinosaur" in that their mammoth bulk simply couldn't get them out of the tar pits of cost and space.
The coda to this is that, once you've used JSO on TSO, every Unix command looks like it's written in the Queen's English by comparison.
Wait, isn't that where Latveria is located?
I know that it's optional around here to RTFA, but the original poster is wrong to title this entry as a move to Linux: this is a primarily move from mainframe to AIX on pSeries, with a few other tasks (FTP) being tossed to Linux like you'd throw a dog a bone. Using this lack of logic, it would be plausible to suggest that the NYSE is "moving to Mac OS X" because a few people in the advertising and marketing department use Macs for their jobs. I realize this isn't Rolling Stone magazine, but the lack of journalistic quality control here at /. is pathetic.
I never trust cost savings estimates by business leaders.
They get raises, bonuses and promotions based on cheery estimations and then leave before the full costs come home to roost.
Still- linux should be a lot less expensive so they have a chance of saving *some* money.

The problem with HA isn't so much hard freezes, power supplies blowing, or even disks failing. None of which happen very often, and for which we have workarounds already.

Hopefully their conversion goes better than the city of Munich's.
It would be very ironic if a piece of free software destroyed the NYSE.
while i might be willing to grant you that for individual trading firms, speed is more important than stability, you cannot make that argument for the whole stock exchange. when morgan stanley or some hedge fund loses connectivity, they stop making money for a few hours. no big deal really. if the NYSE goes down, it's a major economic catastrophe. stability and capacity are the most important things! obviously they need speed to keep up with the demands of the traders, but that just translates to high volume for the NYSE's servers.
If you have a box that scales from a few users to multiple thousands, how do you price the software? The tiered pricing is an attempt to make it close to user based on the assumption that the larger machines are serving more users. The alternative would be to have actual user based pricing.
As someone who started their IT career as a mainframe operator in the early 90's, then moved on to UNIX/LINUX It would be very interesting to see if the cost savings actually pan out. Computers don't stop doing the job they are doing just because they get old. Besides, modern "mainframe" computers are all microprocessor based (no more cabinet sized processors) just like all other computers. OS/390 (or whatever IBM is calling nowadays Z...something?) is just about bulletproof.
I would of LOVED to be in on the powerpoint presentation that convinced NYSE that that dumping their current platform was THE thing to do. It must of been dynamite.
'these machines would have to be a little bit more robust than linux is capable of being at the moment'

To be realistic, they are most likely moving to Linux because of their merger with Euronext and the need for market integration to form the first "transatlantic" stock and derivatives exchange. I'd also like to know which part of their system will be run by Linux, it could just be their messenger system on their Hybrid platform (which the back-up in the flow of messages caused the "big" down day a few months ago on the Dow Jones Industrial). Archipelago, NYSE bonds, NYSE Hybrid etc...which part of NYSE-Euronext is switching?

NYSE on Linux? That's ridiculous. For financial transactions, it's about reliable hardware, isn't it? And you just can't get x86/x86_64 hardware with the reliability of big iron, tandem, etc. And yes, I know Linux runs on other platforms, and no, I haven't tried them, but do you really trust Linux to be as stable on hardware that the entire world isn't already using? Maybe they're just using it for some less important stuff at the NYSE, but at other places (like VISA, MC, etc.) they need the best for transaction processing. After all, if my credit card gets denied because some tech is replacing a DIMM that's producing machine check errors, I'll start writing checks again.
Not only that, but the pSeries boxes practically *are* big iron. They're basically smaller mainframes that run AIX and linux virtual machines.
You're thinking of the old pSeries - the current generation is a Power5 (what would have been an Apple G6, if they went that way) PPC SMP box. They have a nice hypervisor in hardware and they emulate the old pSeries for legacy OS's (as I understand it, haven't tried that part).
You can get a nice rack-mount pSeries for $10K or so. No need to pipe chilled water to it.

Correct me if Im wrong - but isnt the NYSE one of those annoying 'Success Stories' that Microsoft advertises heavily in their online 'Linux information center' adverts ??
.. whatever next ? Next thing they will be claiming that Linux infringes on over 200 Microsoft patents or some such rubbish. Who knows what they are ingesting over there ?
Its some bulldust newspaper article from a rag called 'The Reliability Times', which announces that the stock exchange found that Windows delivers 20 times the uptime of Linux, or some such ridiculous claim ?
You have to love those adverts - I read one last week where they made the claim that Oracle runs 3 times faster on Windows that an it does on Linux
When something this important is moved to a linux operating system it does say something about the rest of the operating systems (well besides eat my dust). For years Linux has been growing and expanding in leaps in bounds due to the support of the oss community. For years Linux has been one of the only operating systems I feel comfortable and worry free with. Don't get me wrong I use windows xp/vista/2k3s and osX, its just that in my experience linux is just stable and my first choice when possible (vendor support in some instances).
I remember interviewing with a company that had a scheme to buffer trades so that they could reduce the cost to execute the trade. They explained the whole thing to me, and at the end, I said something to like, "doesn't it just make more sense to lower the cost of the trade?" What was funnier was that, even though the company was started to persue such a scheme, they never got into it!

I am not so sure, last I heard the migration to Microsoft didn't do well for the core systems, so they were or are planning to stick with HPs Tandem (NonStop) systems.
The main european stock exchanges, managed by Euronext, were migrated to Linux/DB2 on April 10th.
Euronext warrants market is in production on the same platform since July 2006.
Does this mean now that you can hack the kernel to steal from NYSE ... you can fill in the details yourself.
Just before I got laid off (along with a very pregnant woman), they even gave market surveillance over to India. The next generation of cyberterrorists (kids whose families are getting bombed in Iraq today) will have the States by the neck because corporations today are too eager to give up control of their technology to the lowest bidder (Bangalore).
This so-called 'move' actually ties them to a mainframe running DB2, slamming the door on IBM's competition. AIX is just a mainframe LPAR, and Linux for trader workstations is a cheap way to get rid of the dinosaur super-expensive captive-market HP boxes and kowtow to IBM by running their JRE from end to end of every transaction.
When software is migrated from COBOL to C, you gain speed.
Do I need to say more about what you loose?
Even then you would have noticed that MS is claiming patents in Linux (and OppenOffice.org).
Moving to Linux is sending a clear message to MS which says "we do not believe your bullshit".
