Hi Even at $5 a day it is cheap, so lets work with that nice round number. There is no other infrastructure cost, there are no devops support people involved.
So I have been looking at other PAAS, (not interested in anything less thant that) if nothing else than to broaden my understanding of what is out there. Heroku, (just to add auto scaling which it doesn't have out of the box, so you need adept-scale (min $18 per month) or HireFire ($10) on top of what you your paying to Heroku. Openshift does have autoscaling, so you are up for $20 per month, plus usage costs for 3 small gears. So this might be cheaper, but I haven't run anything on it yet to know. There are others obviously but a lot don't seem to provide auto scaling. The App I talked about has a very peaky use, no one uses it over the weekend, big peaks in the morning and afternoon. It's an evidence tracking systems (evidence of work/course material done) and has to be used. There are millions of entities in the datastore and growing. It is a big python application with full role based access control. There is audit trail records created for everything performed in the system. A large part of the system uses AJAX, and it is not really a multipage application, so pageviews are somewhat meaningless form of measurement. There historically has been some unreliability and since moving off M/S to HRD that's pretty well gone away. Any way you cut it $5 a day is a reasonable price for an application that is not relying on advertising for it's revenue.
