It is a common question these days whether to go “cloud” or stay on premises. One of the reasons is the price. To answer this question we use a little spreadsheet that calculates the approximate pricing between Amazon services and on premises custom solution. Of course, there are some assumptions made and the formula is not perfect. However, works for us and probably somebody will find it useful as well.

The scenario in the spreadsheet is for a company wanting to process lots of files (eg. pdf, images). Green cells is input data. Other cells is calculated data. The document is stored using google docs. You can access it here and save a copy in excel if you want to play with the numbers.

Feel free to email me for any feedback, suggestions.
