Starting with the TAM Customer Day you have the opportunity to interact with Experts and R&D during Roundtable Sessions.
This is an awesome opportunity to gain more knowledge and also address questions and issues directly without opening an SR Ticket with VMware.
Another great Event on Monday is the Hackathon which takes place at the very end of the Day.
The reason it is such a cool event is that you have the opportunity to work together with great people from different technologies and cultural backgrounds on a self defined goal.
It is a truly unique experience with so much opportunities to rapidly gain and share knowledge, network and have lots of fun.
