I would like to know if there is any limit at all to the number of Google Cloud Console Project that I can create in my account.
Here is the reason why am concerned:
I will like to run a web service to the public. The web service will utilize GCE instance to run. The web service will run periodically for like say some 5 to 10 hours per week. Each user of the web service can start and stop the service at will. I wish to keep the cost of running the service free to the end users (the public), but unfortunately, google will bill me for the instances I run in their datacenter. So my decision is to make the end user pay only for whatsoever bill I get from the GCE instance that is used to service them for the little time they utilize the service in a week, hence, I intend to setup a cloud project for every user that is using my web service so that cost per individual user could be managed in isolation so as not to under-bill or over-bill users beyond whatever charges am getting from google. Afterall, I would have wanted to keep the service completely free, but since I cannot, at least, I must ensure that they are not over-billed and at the same time save my ownself by not under-billing them. Yes, you may want to suggest that I put all the users under one console project, then divide the monthly-bill amongst users based on the number of hours of instances they run, but unfortunately, the web service utilizes not only gce-instance but other non-uniformly billed resources like network egress which is billed differently based on location - China, Australia being different from others. And infact, tracking accurately the total amount of network egress from a single user under a shared console project will be very difficult, if not impossible. Hence the need to create a single project per user.
Now, my concern is that, in the future, if the number of users that use my service grows to 20,000 and even say 100,000, the number of cloud project that I would have setup in my account would be 20,000, or even worse, 100,000. Is this possible?
I have not found any statement online regarding the limit of the number of projects that can be created under a single account. So do you, or anyone know if there is a limit that google places on the maximum number of projects that can be created under a single account.
