David Marshall has been involved in the technology industry for over 19 years, and he's been working with virtualization software since 1999. He was able to become an industry expert in virtualization by becoming a pioneer in that field - one of the few people in the industry allowed to work with Alpha stage server virtualization software from industry leaders: VMware (ESX Server), Connectix and Microsoft (Virtual Server).

Through the years, he has invented, marketed and helped launch a number of successful virtualization software companies and products. David holds a BS degree in Finance, an Information Technology Certification, and a number of vendor certifications from Microsoft, CompTia and others. He's also co-authored two published books: "VMware ESX Essentials in the Virtual Data Center" and "Advanced Server Virtualization: VMware and Microsoft Platforms in the Virtual Data Center" and acted as technical editor for two popular Virtualization "For Dummies" books. With his remaining spare time, David founded and operates one of the oldest independent virtualization news blogs, VMblog.com. And co-founded CloudCow.com, a publication dedicated to Cloud Computing. Starting in 2009 and continuing all the way to 2016, David has been honored with the vExpert distinction by VMware for his virtualization evangelism.
