Hi,

We are running Firebird 2 in an Azure VM. It can only take so much in terms of concurrent connections.

What top-level advice would you give to scale this?

We are connecting to it from a .NET core Middleware using Azure VMs.

The architecture of the middleware is quite monolithic. We are considering rewriting it with Microservices and Azure functions or similar architecure, but are unsure how we could scale the Firebird DB or connections itself.

Multiple casehandlers in our company use it via a Delphi-based Windows application at the other end, with a vendor maintaining the Firebird DB and Windows app development, so we are locked into using Firebird.
