Hello, I decided to use AppPlatform for my start-up. Architecture: Frontend:Flutter Mobile App Backend: PHP API (AppPlatform 1 GB RAM | 1 vCPU x 2) Database: Managed PostgreSQL (2 GB RAM / 1vCPU / 25 GB Disk) CDN: DigitalOcean Spaces

I couldnt decide is this configuration is enough for production? I think DO doesnt provide autoScaling for appPlatform. How can i decide “I need more App” or how to test DB source is not enough? What are the limitations for Managed Postgre. How many concurrent connection can be handled for this architecture?

I know sizing is not easy

Which documentations should I check?

Regards, Mehmet.

Welcome to App Platform, excited to have you here! As you said sizing is not easy, and it’s difficult to recommend sizes because every app is designed and architected for different needs.

With that said, trying to figure out what “units” of resources can handle (eg. 1 vCPU/1GB RAM) then scaling that to cover your current load plus some works well. The way I would attack this is look at what resources your app uses under regular load. In App Platform this can be found under insights. Once you find that you’re going to want to try and add a little buffer room so that when you get bursts of traffic your app will continue to function as expected.

One of the great things about App Platform is it’s so easy to scale up and down when testing.

Hope this helps!
