CompTIA Cloud+

This is a popular non-vendor certification that's useful to validate overall professional capabilities around cloud technologies.

"CompTIA’s Cloud+ certifies your in-depth understanding of cloud terminology and methods for adopting the cloud," according to David Linthicum, CEO of Cloud Technology Partners. "If this sounds more basic than the AWS training, well, it is."

But the certification is a good place to start when looking for technology-agnostic training.

"I recommend it for cloud developers and administrators who are just getting started on their cloud computing journey, and who want to cover the basics to move beyond their specific technology skills," Linthicum said.

The average salary of a Cloud+ certification holder in the US is $93,122, according to the 2017 IT Skills and Salary Survey conducted by Cary, N.C.-based business training and certification company Global Knowledge.
