Ignite in Orlando has already come and gone, and now you can watch many great sessions on Azure Stack right from YouTube! Later they will be also published on Channel 9. The advantage on the latter is that then you can also grab the session slides, in addition to the downloading the videos. Where on YouTube you can only stream them.
Get ALL the Ignite 2017 sessions a aka.ms/Ignite/YouTube
Get the Azure Ignite 2017 sessions on the Azure Channel on YouTube at aka.ms/AzureStack/YouTube
Currently I also have the Ignite 2016 sessions at aka.ms/AzureStack/Ignite, but once the 2017 sessions are uploaded to channel 9, I'll update this link. While many of the 2016 sessions are still relevant, I would always check the latest conference sessions first :). So for now, hit the YouTube channel. Then stay tuned for the Ignite session uploads to Channel 9!
