On top of that is the full-steam-ahead push to the cloud for everything, including network infrastructure. I sure hope this works, since almost everyone is now betting heavily on the cloud. I'm sure things will work out in the end, but right now, this is where you have to be to win or keep business - even if the business model isn't all there yet.
Avaya's news - and emphasis on "fast track" - got me thinking more about where UC is going, and that's what my current writeup for UCStrategies is about. I'm not sure if Avaya's "fast track" ultimately refers to them or their customers, but it really doesn't matter. What matters is getting to the cloud now, hopefully before your competitors do.
Just as the cloud is now superceding premise-based deployments, something else could come along a few years from now to supecede the cloud, but let's not go there yet. Instead, please go to the UCStrategies portal now, and I hope my post gives you some food for thought.
