The basics are always harder

Initiating the deployment of new technologies in a production datacenter is done after gaining expertise, thoroughly testing them in "the lab" and best guessing how scalable they are.
The questions are:
Is expertise available?
How expensive is it?
Can we do it fast enough?
Are we getting caught in proprietary rathole?
Can we scale them? Will we have a site blackout due to these changes?

Ah, don't forget, are these technologies really effective?
