I would like to thank my wife for her continuous friendship, love, and support throughout. She even supported me when I took the risk of quitting my job to to pursue a skill, in which I had no experience. I would also like to thank my twins for allowing me some spare time to review Joseph's book. Further, I want to thank the Salt community for teaching me new things everyday. Last but not least, I would like to thank God.

I love learning new things. SaltStack gave the opportunity to learn more about Salt, which made me grow as a Python coder and enthusiast. I would like to thank SaltStack for their continuous belief and encouragement to the point of inviting me to join the team.

Darrel Clute is an IT infrastructure architect. Throughout his career, he has predominately focused on network engineering. Darrel has also spent an equal amount of time focusing on systems engineering, primarily with Unix-based systems. Apart from his job, he is also an advocate of the open source software.

His knowledge and experience with IaaS solutions—such as OpenStack—is constantly increasing as well.

Beyond his core infrastructure, Darrel has recently been developing programing skills to augment his daily activities. Throughout his career, he has utilized various languages and utilities to automate infrastructure. Some of Darrel's programming has been with the use of Bash, net-snmp, sed, awk, and holistically Python.
