Familiarity with OpenStack is likely to continue to be one of the most in-demand job skills in the new year, both for developers and system administrators. But OpenStack is a huge area, encompassing dozens of individual projects with varying degrees of complexity. Building and keeping up your skills can be a challenge.
Fortunately, there are lots of resources out there to help you learn what you need to know. In addition to the official documentation, numerous training and certification programs, books, and other resources, there are also plenty of community-created tutorials, guides, and how-tos out there created by OpenStack developers and users who wish to share their first-hand knowledge.
