Unless you have been hiding under a gigantic UC rock, you will have no doubt seen the recent announcement from Microsoft around Skype for Business Broadcast Meetings.
Further enforcing the agile software release strategy of Cloud first, On-Premise second – should you fall into the latter category, this is the first Skype for Business feature release that is explicitly going to depend on hybrid connectivity being in place.
In Lync Server 2013, Hybrid connectivity always felt like an afterthought, something to bolt on, to help you get from A to B but there was never any real feature benefit from doing so (IMO – it was purely for migration purposes).
With Skype for Business, this has now changed – there will actually be scenarios where hybrid connectivity is required to not only allow for selective user placement and migrations, but also to enable specific functionality, Meeting Broadcast being the first.
