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.

Windows or Linux Hosting - Which Is Right For You?If you're a new or casual Webmaster and your site is non-revenue generating with static HTML pages you generated from boxed software, you probably are hosted on a Linux server. This is the best solution overall for you because Linux hosting costs less and you hardly ever need to delve into the more advanced functions. Server operating system becomes a non-issue. All you need to do is to have a good host.
