An application cloud company called $4 wanted to know which applications were most in demand.
It collected job listings from jobs site Indeed on the 50 most populous U.S. cities and then looked at more than 200 business software platforms to determine which tech skills are most in demand.

But when it came to the tech skills required for developers, the cloud dominated, particularly one cloud: Amazon's.
