Webfarms: The Only Way To Host!Networks can be configured to be so incredibly redundant now - for reasonable prices - that there is no excuse for a data center not to achieve five nines (99.999%) of availability.
But what about the servers and applications? Why spend so much time up front configuring the network to make sure it doesn't fail, and then deploy an application to a single server?
Sure, there are ways to make sure individual servers have some redundancy to minimize failures -- things like RAID1, RAID5, or RAID10 (redundant array of inexpensive disks) which will protect against a disk drive failure (and I highly recommend this type of configuration for all production servers - and preferably the use of hardware RAID vs. software RAID). But what happens if a file gets corrupt on the RAID array? Or a recent configuration change brings the application down? Or a newly released patch conflicts with other settings and causes problems? Well, in these situations the server will go down and the application(s) hosted on that server will be offline.

Keep your web host from costing you money
Now that you've probably just spent hundreds of hours and possibly even thousands of dollars to build your web presence, one of the most important decisions you'll make next is where to host your website.
Choosing a Platform It may be true that Unix tends to be more reliable than NT, but it is even more true that any server when overloaded with sometimes 250+ web sites, like most web hosting companies do, will not be as stable as you need it to be. Don't expect your site to incur 100% availability if you are on a shared virtual server. There are too many things that can go wrong when 250 different sites are competing for the same resources. If your web host doesn't publish how many sites they put on a single server, find out from them, they shouldn't have anything to hide. By the way, 255 sites is the maximum that Windows NT will allow per server, and most web hosts take full advantage of that for their lower end solutions.
Web sites running on NT/Windows 2000: *Rapid application development with scripting languages such as ASP or Cold Fusion. *Typically is easier to administer in a shared hosting environment. *If need ODBC to support database driven a site. *FrontPage tends to work better on NT
