Enable Dedicated Hosting Plan

  • Article

One of the features of Azure Monitor for SAP solutions is that it uses an Azure function to collect and process the data from your SAP systems. The service deploys and manages the Azure function, so you don't need to configure or maintain it. However, you may want to optimize the cost and reliability of the Azure function based on your monitoring needs and usage patterns.

This new feature allows you to switch the hosting plan of the Azure function that is used inside of Azure Monitor for SAP solutions. With this feature, you can migrate to the dedicated plan for the Azure functions. The hosting plan of the Azure function determines how the function app is scaled and billed.

The Dedicated hosting plan has a significant improvement in cost and scaling efficiency when used on AMS
