We have a requirement where we need to cope with multiple requests being sent per second into our system

Is there a specific reason to not use Azure Functions for this over a standard Web API hosted in an Azure App Service?

We would use a premium function

My preference would lean to functions would just be interesting to see if this is the best way to follow current best practice

I have tried multiple requests into a function and it’s fine initially then starts returning errors but it’s unclear if this is an issue outside of the function and whether functions are not supposed to be used in this way
