Backends CPU Usage

[Volker Schönefeld]

Since running a single B1 backend, the CPU usage of our instance has increased by an order of magnitude. Nothing else has changed.

So my question is:

In addition to the explicit backend cost, does the backend cpu usage count towards the CPU Time resource on the front page? Or is this "indirect" cost because the backend uses the datastore API, and that is billed as CPU time?

Considering that the cost of the CPU time is about tenfold that of the backend, this is a nasty hidden cost and I think it should be made more explicit.

Cheers,

Volker

Hi Volker,

The running of Backends is only charged as Instance Hours but as you highlighted they can call APIs which consume CPU Hours (under the current model).  So if you are doing datastore operations on your backends that is probably why you are seeing CPU Time being used.
