The global market for “cloud computing” — that fluffy word for services delivered over the Internet — is going to increase from about $41 billion in 2011 to $241 billion in 2020, according to new estimates from research firm Forrester. It’s the latest report trying to get a handle on the cloud computing business, which is growing quickly and driving investment in things like data centers — vast warehouses of computers that power the Internet. It’s always risky to predict such things so far in advance, of course. Attempts to estimate the potential value of cloud computing vary: Another firm, Gartner, projected that it will have revenue of $148.8 billion by 2014, higher than Forrester’s forecast of $118.7 billion for the same year.
