      About the Author

      Jonathan Frappier is a hands-on technology professional with over 15 years of experience in VMware-virtualized environments, focusing on system interoperability. He has specialization at the intersection of system administration, virtualization, security, cloud computing, and social enterprise collaboration.

      He had not touched a computer until high school but then quickly found his passion. Jonathan holds a Bachelor's degree in Computer Science from Newbury College and a Master's degree in Computer Information Systems from Boston University, which he completed while working full time. He holds VMware certifications, including VCAP5-DCD, VCP5-DCV, VCA-Cloud, DCV, and WM.

      Jonathan has worked in enterprises and start-ups throughout his career and has become a self-defined jack of all trades, but he is most passionate about virtualization and its community, and was honored as a vExpert 2013 for his contributions.

      You can find Jonathan on Twitter @jfrappier, and on his blog at www.virtxpert.com, as well as at almost every Virtualization Technology User Group (VTUG) meet. He also supports the #vBrownBag podcast at professionalvmware.com.

      First and foremost, I'd like to thank my wife for putting up with me for all these years and my daughter who will have to put up with me for many more. I am thankful to my parents for supporting me even when I had no idea why I was going to college. I would also not be here if it were not for my grandparents, who I was fortunate to know well in my adult life, and in loving memory of my grandfather, Norman L'Heurex, and Pepere Lionel Frappier. Just as much love is due to my friends Jim, Jeremy, Manny, Bob, and Igor.

      I'd also like to thank the following people from the virtualization community: Matt, Sean, Luigi, and others—the Nerdherd. I'm not sure I'd be doing this if it weren't for that dinner at Ichigo Ichie. Also, a big thank you to the #vBrownBag crew for giving me the opportunity to give back through this incredible organization; to all the folks out there blogging, sharing, and helping others; and the folks at VMware who support the community. Your contribution inspires me.
