Datastore costs? #2

Closed ajck closed 7 years ago

ajck commented 8 years ago

This is excellent, thanks very much for releasing.

Just wondering is there any way of getting an idea of Datastore financial costs for using this, e.g. per user on a site - i.e. storage costs and Datastore operations costs? How would one calculate this (even roughly)?

Thanks again.

You're welcome!

Costs should be reasonable - although I've not done the maths yet!

The system comes with a memcache layer for reading when possible, so Datastore reads are minimised.

As an FYI, here are the basic costs

@ajck we've been using our own, maybe not so well written version of this as part of Laravel over at a1comms/GaeSupportL5 for a few months now on a site with about 1,000,000 monthly page views, of those about 300,000 being unique visitors generating new sessions. We use Datastore for more than just sessions, so it's not a great comparison, but even so we'd be lucky to spend 5 GBP outside of the free tier per month on Datastore, with a small amount of dedicated memcache to aid caching at about 30 GBP per month. Overall, I'd say it's a great storage layer for performance and pricing, the only downside being it's not so easy for the developers to work with, but arguably worth the trade-off.
