Cost Savings vs. Appengine

[iceanfire]

I'm co-founder of a company that uses Appengine quite extensively. A senior developer has suggested that what we pay per day on appengine would be our monthly cost (based on our usage statistics) if we switched to amazon. Basically 30x lower costs, 10x savings if we're conservative.

I'm wondering what the experience in this community has been? Is appengine in-ordinately expensive? Does switching to Appscale give you more control to save costs? Has anyone seen cost savings in switching?

Hello iceanfire,

from our experience costs varies dramatically depending on how your
application is using GAE APIs. The savings you mention seems a bit
higher, but not completely off on what we have seen ourselves with
AppScale on GCE or AWS. In short, App Engine is a very good model that
free the dev from even having to think about OPs, ie you have a saving
factor for not having to think about scalability, reliability,
availability etc ...

We have also heard of people going directly to the bare machine (ie not
using App Engine model anymore), and in this case you may need to
factor in the cost for the OPs I mentioned before. That is the
application will have to be coded to be scalable, reliable and
available, as well as make sure you have the proper configuration and
reliability, availability, and scalability for all the software
packages your application uses. Depending on the complexity, you may
have quite a cost in time and OPs to pull this move.

Have you tried to run your application on AppScale on some GCE or AWS
instance? It should be pretty easy to do a quick tests to have some
reliable numbers for your application.

cheers
