Microsoft has posted all of the content from their Microsoft Ignite 2019 Sessions, including videos, slides, demos, and other content! You can access them by visiting https://myignite.techcommunity.microsoft.com/sessions.
I strongly recommend the OPS[10|20|30|40] track if you are at all interested in streamlining your organization’s operations. All 5 presenters (David Blank-Edeman: OPS10, Jason Hand: OPS20, Jeremiah Dooley: OPS30, and Neil Peterson: OPS40) were all super knowledgable and were great to chat to after the sessions too. Their sessions were not Azure-specific, but rather focused on operations in general. All 4 sessions were hugely beneficial to me and I hope they are for you too.
If you are in any kind of position that has any sway over the IT or IS arm of your company, you should definitely check out the Microsoft Ignite 2019 sessions content as I am confident there is something valuable in there for everyone.
