Iwan 'e1' Rahabok was the first VMware SE for strategic accounts in ASEAN. Joining VMware in 2008 from Sun Microsystems, he has seen how enterprises adopt virtualization firsthand, reaping the benefits while overcoming the challenges. It is a journey that is still going on and the book reflects a subset of that undertaking. Globally, he was one of the first to achieve the VCAP-DCD certification and has since helped others to achieve the same with the help of his participation in the community. He started the user community in ASEAN, and today the group is one of the largest VMware communities on Facebook. He is a member of VMware CTO Ambassadors, representing ASEAN region at the global level and the product team and CTO office to the ASEAN customers. He is a vExpert 2013 and vExpert 2014 and has been helping others to achieve this global recognition for their contribution to the VMware community. He graduated from Bond University, Australia, with a degree in IT in 1994.
