Mission critical falls on Windows? rofl... OMG I GOTTA GET MY QUICKBOOKS DATA UPDATED THIS IS CRITICAL ALSO NEED TO CHECK MY HOTMAIL
Are you really that much in the dark?....Quick Books and Hotmail?...Seriously you really think that's it? I said corporate
desktops, again...not dicking around at home or playing with some mom & pop code.
Local, state, and federal govt. all rely heavily on desktops to achieve their daily business...ever noticed what those machines are running at your local tax assessors office? How about the machines at the courthouse when you go in to pay a ticket? Or what about damned near every public school system in the world? How about the USAF utilizing SharePoint to run scheduled supply drops in Iraq...food, medical supplies, ammo, pretty much anything that the troops need...they are accessing those SharePoint front-ends running on SQL back-ends through, you got it, Windows desktop clients.
....or we could discuss a little real estate firm called Merrill Lynch...I believe their last contract renewal saw close to 100K desktops....desktops that are used to access a whole plethora of mission-critical internal resources related to their business....web apps that run on IE, email through Exchange with Outlook as the email client, which of course runs on top of Windows desktop....and yes, email is considered mission critical to a company like ML, as that is the #1 mode of communication with a lot of their clients.....same as many many other big players out there....not just real estate, also big playing financial institutions like Fidelity, Ameritrade, Smith Barney, etc....law firms, universities, communications companies.
Some other big desktop folks are the oil companies...I happen to know that Shell uses a proprietary app for their drilling architecture and platform manning services...this app runs on Windows. (Although it used to run on Linux until they got fucked on that and ended up with a catastrophy that cost them roughly $100M over about an 8-week period).
Health care industry is another huge place where Windows desktops serve in mission critical environments. Baylor Healthcare, Calgary Health, Cambridge Health, Cardinal Health, NHS covering all of greater Europe (just to name a few)....medical staff uses Windows clients to access and update patient records, RX, etc, etc. If their client failed, they may not know when to give you your next shot of hormones, or that dose of Ritalin.
The thing is, you have to remember that the term "Mission Critical"...is not always going to be just your servers running in the back end, it's dependent on the individual business and end resulting impact that can be caused by any one aspect. We have famous authors that consider Microsoft Word
as their Mission Critical app.
Hell, a month or so ago I dealt with a Crisis situation that was all based on Windows Mobile....yes, Win Mobile was the "mission critical" app for this customer. It was a high-end Limo/Towncar service...This company utilizes a combination of Win Mobile and GPS to track drivers and dispatch all over the place....without Windows mobile they are screwed.
