OpenStack continues to be one of the most in-demand skills in the tech industry; if you’ve got solid OpenStack experience, you’ll almost certainly be able to find employment with it. But how do you gain those skills, and once you’ve gained them, how do you keep them current?
Fortunately, you’ve got plenty of options.
There are many choices, from the help of the official project documentation, a variety of in-person and online training and certification programs, and lots of printed guides and books. In addition, there are also a number of great community-created resources. Every month here on Opensource.com, we bring together the best of these for you into one handy package.

That brings us to a close for this month. Should you still be looking for more, be sure to check out our collection of OpenStack guides, howtos, and tutorials spanning almost three years of community-generated content to help you learn to be an effective OpenStack developer or administrator.
