I'm currently a visitor of the Microsoft Ignite Tour in Berlin.
There's everything about Teams, Azure and it's cloud services. Day 1 was a lot about getting to know azure services and I visited the dev learning path's sessions. One of the highlights of the first day was the presentation of Paula J, founder of the security company cqure. She explained in a pretty astonishing way how a windows account as a part of a domain can be hijacked and passwords can be stolen easily with the right tools and knowledge level.
Something else that was quite interesting was the pricing model of the azure functions which are calculated in GB/s and exec/month. As 400.000 GB/s and 1million execs are free, you just have to pay the storage where the stuff that's calculated or moved is hosted as long as you don't exceed the given values.
