Azure App Service is a service used to create and deploy scalable, mission-critical web apps.
@Jonathan Pinillo , Thanks for the great question!
AFAIK, some % of the memory is utilized for system processes. I'm checking on this internally and will get back to you shortly.
As I understand, in your ASP without any Apps (which is empty running under it, you're noticing 75% memory consumption, is that correct? where exactly (/graph/metric) do you observe this? Pease share a screenshot after concealing any PII info.
Just to add clarity on the terminologies:
App Service – PAAS solution which enables you to build and host websites, mobile backends, and Web APIs.
Apps– Your individual Apps (Windows/Linux WebApps, Web App for containers, and Azure Functions), these apps run in App Service Plan.
App Service Plan (ASP) - An App Service plan, at high level is a container in which your apps run, ASP defines a set of compute resources for apps to run.
