As happened in the previous years, there will be a VMware Online Forum 2013 edition that is quite similar to a vForum event (now called VMware Forum) with the main advantage to be just an on-line version that gives you a flexible, convenient way to expand your knowledge and experience the event in a way that fits in with your busy schedule.
The 2013 edition will be on Tuesday 23 April starting from 8:30 Pacific Time. Also this year I have an Online Chat Session, focused on “Virtualization with vSphere” scheduled on 10:30 AM – 11:00 AM PT.
