What are the benefits from using Cloud Computing services or platforms? Cost efficiency, shorter innovation cycles and scalability are frequently mentioned promises. However, the value proposition of Cloud Computing obviously depends on the corresponding business scenario. You cannot properly value the benefits from using Cloud Computing services unless you know and understand the relevant parameters of your project.

The question is: which are criteria that make Cloud Computing services a valuable infrastructure for certain projects? Which are criteria that have a negative impact?

This is an attempt to find criteria that might be helpful in categorizing Cloud Computing business scenarios. Feel free to leave comments…
