As the book is somewhat limited in page count I was not able to cover as much as I would have liked. That said, there is a wealth of information available if you know where to look.
This page has been included to contain links to external reference materials (websites, blogs, reading materials, etc) which complement the book and should give the reader other avenues to find the information they are looking for.
What follows is a list of people who are actively involved in the agile, continuous delivery, and DevOps communities:
- Patrick Debois is seen by many in the DevOps community as the daddy of DevOps and the founder of the DevOpsDays movement (http://devopsdays.org). This relatively small get together of like-minded individuals in 2009 has grown into a global gathering. For more information on Patrick Debois, visit http://www.jedi.be
