John Hales — Co-Founder

Courseware Designer, Technical Editor, Instructor, and Consultant

John has been working in the IT industry for more than 20 years, including 17 years with a variety of Microsoft technologies from Windows and Active Directory to SQL and Exhange. He has been active in Storage Area Networking (both Fibre Chanel and iSCSI) and virtualization, and has used VMware products for more than 14 years.


John has earned many vendor certifications over the years from Microsoft, EMC, VMware, Novell, and CompTIA. His certifications include: MCSE (NT 4, Windows 2000 & 2003, MCTA, MOUS), MCDBA, MCT, VCP, VCAP-DCA, VCI, CNA, CNE, EMCSA, Network+, and A+.


He has taught, developed courses for, and consulted on many of these technologies, both for individual end users and for customized, internal training for Fortune 500 companies. He has taught in North America, Europe, Asia, the Middle East, and Australia and has met with success in each location.


John is a prolific writer and has developed many types of books and study aids. His writings include, but are not limited to, quick reference guides on topics as diverse as Word, Windows 7, Linux, and Computer Terminology for BarCharts; exam preparation guides in various formats, including books with exam review questions (such as the CoursePrep ExamGuide for various MCSE exams); summary technology guides on A+ and Network+ for BarCharts; and “tips and tricks” format books such as the 24x7 series book on Netware 5 by Sybex. His latest book is Administering vSphere 5: Planning, Implementing and Troubleshooting.


John’s experience with Storage Area Networking came from the need to provide the space and performance for applications such as SQL and Exchange, whereas his experience with virtualization grew out of the need to learn new products without filling his home with computer gear. He has also used virtualization for many development projects as well as helped customers use virtualization technologies to meet business objectives (including cost and power savings and disaster recovery).


John’s experience in this area began with VMware Workstation and progressed through various desktop and server products and releases. He has also used Microsoft’s products, from Virtual PC and Virtual Server to Hyper-V. John is a strong proponent of virtualization.

Today, John develops courseware for companies large and small and teaches an assortment of classes for various vendors, specializing in Microsoft technologies, VMware's Virtual Infrastructure 3, vSphere and View technologies, EMC storage, and how operating systems (such as Windows 2008) and applications (such as SQL and Exchange) can best exploit these technologies.


John is the president of Hales Technologies, Inc. and a founding member of The Courseware Group. He can be reached at or via phone at +1 (954) 309-0137. He can also be found on the web at
