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.

Sorry, sometimes I mistake your existential crises for technical
insights.
