Hi, a have some questions of the performance component.

How many connections I can use on the server side?

How to make hardware sizing for 3000 connections?

I guess you should just test. Each environment is different. RemoteDB was not designed for a super-scaled web server, even because only Delphi clients can connect to it. The purpose is to make it easy to "move" an existing traditional client-server application to the cloud, by accessing a database remotely. We have reports of users using 300 users, but as I said, each environment is different. Note that the server is only accessed when an SQL is executed by some client.
