Depends upon the type of apps, amount of required concurrency, etc.
It's easy on the front-end (which is where most of the drama tends to
take place, anyways); it's the middle and back-end tiers which require
some work, but it certainly can be and is accomplished daily, for both
simple and more complex systems.
The smart money makes use of various existing *aaS platforms to
accomplish this without having to re-invent the wheel every time.
