This is Variegated, the blog of Alan Hohn.

I’m a Lockheed Martin Fellow with a background as a software architect, lead, and manager. I’ve got a lot of experience re-architecting embedded systems, mostly using distributed Java, and in combining embedded and enterprise approaches. Lately I’ve been doing quite a bit of work with virtualization, DevOps and cloud technologies.

Over the past several years, I’ve had the opportunity to teach some courses, both introductory and advanced. That’s meant writing quite a few examples. My role and interest also mean I frequently try out new libraries and new approaches. My hope is that some of that material will be as useful to others as I’ve occasionally found it.

I’m the author of Hands-On Infrastructure Automation with Ansible and Hands-On DevOps with Ansible, video courses from Packt Publishing that teach Ansible using real-world examples. I invite you to check them out.

Career information is available on my LinkedIn page. I’m employed by Lockheed Martin Rotary and Mission Systems. All views on this site are my own and do not necessarily reflect the views of Lockheed Martin.
