Are there other reasons holding you back? I ask because the two you have listed could both be overcome. The simplest design I could imagine would be for you to code your own authorization and accounting system within your app. It would take some work, but would presumably pay for itself in terms of keeping your customers and also gaining new customers. That is, the app would accept login from all Google accounts, but then your code checks the accounts against ACLs maintained by the app itself. You'd need to also write an admin page to allow the customer to add or remove folks from the ACL, but this is also somewhat better because now you could control the UI here. In terms of accounting, one simple solution would be for you to run a mapreduce each night to compute how much space/ops is used for each customer. Then, customers using lots of space would be billed. Given that, as you say, most customers use very little resources, you should only need to bill your top customers specially.
The alternative would be for you to work out a special contract as a Premier Account, so that all of these apps were billed to your Premier Account instead of to the customer: http://code.google.com/appengine/docs/premier/index.html On Wed, Nov 9, 2011 at 4:42 AM, Daniel Florey <[email protected]> wrote: > Hi Emlyn, > running as a multi-tenancy app is not doable for several reasons: > - Clients want to be able to protect the data by managing the permissions > (=access to the datastore) by themselves > - The app can use a lot of resources depending on the settings of the > customer.
