i have Angular in Azure Devops Build and Release Pipeline which puts it on a Azure Web app. I have Express with MongoDB as Backend, but where would be the best position to put this on? Another Azure Web App or where?

I think it would be nice to also include those into the build and release pipeline in azure devops, i would have 2 artefacts which i could then use in the release pipeline.

I think i am just a little confused and need a pointer in the right direction :)
