A:
Pricing wise there is no difference between cloud or
on-premises deployment. Each option has some pros and cons and eventually they cancel
out:
a) With Cloud API you do not need to run your server. So
you may save a bit of money.
b) With OnPremises deployment you have full control over
your hardware scalability etc (you are not sharing sever with anyone). Also
your file are not leaving your corporate entity (even though cloud api offers
secure processing, some companies have policies that do not allow file
processing by third parties... regardless of our guarantees).
