Infrastructure costs for web applications

Google has published a financial report for the 4th quarter of 2006. It says that the cost of operating data centers and accepting credit cards increased from 8% of turnover in the third quarter to 10% in the fourth quarter.

Jason Hoffman , co-founder of Joyeur , a company specializing in hosting web applications, writes about the fact that this cost estimate can be used for most web applications when calculating costs for performance optimization or, if you look at the question from the other side, planning the necessary income.
