Actually, some of the biggest use this type of cloud hosting.  Have you ever heard of Google?  Yahoo is another.  Then there is that start-up company that may catch on one of these days called Facebook.  It will be reported in the news every once in a while that so and so is building another server farm somewhere.  That is what they are doing.  They are spreading the workload around and the risk of data loss.  When you are talking about the amount of data, the number of visitors and the money that is made by these entities, it is no wonder that they want to do everything possible to safe-guard their investments.  That is something that you can participate in as well.

Many of the shared hosting companies are moving to this type of hosting because it just makes sense.  With all the new web sites going up every day, the data is being transferred to all points of the globe on an every expanding basis.
