Cloud computing vs. colocation: What's the difference?
Let me offer you an analogy to answer this question. Colocation is like getting a refrigerator that is the size I choose and, to a certain extent, organized the way I see fit. It comes with a guarantee that it will stay cold and preserve the food items I store in it. Cloud computing is more like getting a Star Trek replicator. If I ask for a cup of ice cream, it is created for me. When done, the replicator recycles the cup.
Colocation involves renting space populated with items I choose in advance. I also have the ability to organize the items the way I want. Cloud computing, on the other hand, offers me what I want (as long as it is in the service catalog), when I want it and for as long as I want it.
