Microsoft O365 licensing and the costs associated with it can be a challenge for enterprises with a mix of users requiring different functionalities.

End-user computing (EUC) in the hybrid workspace

So I recently had the opportunity to do a webinar for VMware about something that I love, EUC, and combining this with a hybrid workspace!
