@JonathanPoveda-3686, 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.

@JonathanPoveda-3686, Following-up on this, Yes, to the support the platform, some memory is utilized. On a small instance, the minimum threshold for memory consumption will be likely over 50% to start with. If you have any questions please let us know with the requested details. Thanks again for the question.
