title: Is the 1.5 GB memory limit in Azure Functions limited to the entire Function App or per function invocation?
body: <p>I'm setting up an Azure Function app that has multiple timer triggers that are triggered at or around the same time. I'm confused by the wording here: <a href="https://docs.microsoft.com/fi-fi/azure/azure-functions/functions-scale" rel="nofollow noreferrer">https://docs.microsoft.com/fi-fi/azure/azure-functions/functions-scale</a>  </p>
  
  <blockquote>
    <p>Each instance of the Functions host in the Consumption plan is limited to 1.5 GB of memory and one CPU. An instance of the host is the entire function app, meaning all functions within a function app share resource within an instance and scale at the same time.  </p>
  </blockquote>
  
  <p>Does that mean that each script that is executed with a timer trigger is allocated 1.5 GB of memory or does that mean that all of the scripts share 1.5 GB of memory that are running at the same time?</p>
