Microsoft Build is happening on May 23-24. Both Build and Ignite are big events at Microsoft; many product groups prepare to have something interesting to present.
This year there is likely going to be some information around artificial intelligence. Next to that I personally love to hear from personalities like Satya Nadella, Scott Guthrie, Scott Hanselman, Mark Russinovich, and many others.
You can register here.
That is all great, but what is in it for me? Well, good that you ask :-) There are cloud skills challenges, that help you learn about a specific area. And during the month after build you can get a free exam voucher for completing them. Note that you can only get one exam voucher. And if you are interested to do a specific exam, you should do the corresponding challenge, see below.
Thanks for reading! :-)
