AWS vs Azure Services Comparison Cheat Sheet
To help you learn the different Microsoft Azure services, we’ve come up with this AWS vs Azure services comparison. If you already have some background in AWS (or cloud computing in general) either through work experience or AWS certifications then you won’t have a hard time learning Microsoft Azure.
