Azure App Service Plan Consumes 70% of Memory Without Deploying Any Code

Question

In Azure, I have created an App Service Plan (ASP) and a web app using Node.js 20 as the runtime stack with Linux as the operating system. This web app has no code deployed yet. Once I mapped this web app to the ASP, the ASP shows 70% memory usage.
ASP configuration:
Plan Name: Free F1
ACU/vCPU: 60Minutes/day
vCPU: NA
Memory: 1 GB
Remote Storage: 1 GB
Scale: NA
SLA: NA
Cost Per Hour: Free

Hi @Shanthi Even with no application code, the Linux operating system and Azure App Service runtime consume some memory for essential processes. These include system services, startup scripts, and monitoring agents but it shouldn't use up to 70% of memory.

Also, Azure App Service uses the Kudu service for deployment, management, and debugging tasks. Kudu itself has some memory footprint, which might contribute to the overall usage. You should acccess the Kudu service for your web app instance. You can usually reach it at https://<your-app-name>.scm.azurewebsites.net. Look for a section displaying resource usage (CPU, memory). This might give you an idea of how much memory Kudu is consuming.
