It was huge and it was great! For the first time I have a chance to attend VMworld 2017 in Barcelona and I really enjoy that. What I really liked was roundtables where you can easily discuss within small group with VMware employees about different topics as well as experts table which ware more like 1:1 meetings.
Fortunately almost all sessions ware recorded so even if you did not have a chance to attend you still can learn a lot.
