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.

5 good reasons why you may need to change your web host now, before it is too lateThere is a very high possibility that changing your web host now could actually save you a lot of grief in the near future. In the past people have hardly paid attention to their web hosts and have thus been ignorant to the fact that this is a choice that makes a huge impact on performance and ultimately the success of any online venture.
1)Security at your web host matters The security settings of your web host matter. They actually matter a lot. So much so that the security of your site from hacks and all the other increasing online dangers depends on it. An intensive review of your web host may lead you to look at a few other web hosts and their infrastructure with the intention of moving your hosting elsewhere.
2)Ddos attacks on another site in your hosts network will affect you The danger of Ddos attacks is on the rise. Ddos or Distributed Denial-of-service attacks have been targeted at various well known sites in the past costing losses.
These are the attacks where massive false online traffic is generated towards your site, thus crippling it. The attack is executed when thousands of compromised zombie hosts are directed against a target. These zombie hosts are unwittingly recruited from the millions of unprotected computers online and are quickly build up waiting for the command to launch a Ddos attack. The symptoms are that a site receives impossibly high false traffic that literally shuts it down.
