Overhead expensess and transperancy
"Cost Transparency is one of the few tools for measuring both external and internal IT value based on the amount of work done. Amazon and Microsoft Azure are two of the three largest and fastest growing cloud service suppliers, with the Google Cloud Platform the third member of the triumvirate, according to Gartner's Lydia Leong. Amazon is the leader in market share by a wide margin."
