VMworld 2021 Top 10 session to watch

vmworld2021It is that time of the year again to start looking forward to VMworld 2021. Due to the ongoing Covid-19 pandemic VMworld 2021 will again be “fully virtual” again.

You can follow the conference from the luxury of you own chair and desk. Poor your own drink of choice, sit back and relax and take in all the information on VMware latest and greatest from your own home. Because VMworld 2021 will be fully virtual, like last year that will make it easier for people to attend since you don’t need to arrange travel (flight/hotel) to attend VMworld.
