Microsoft Graph Training Module - Optimize Network Traffic with Microsoft Graph

Learn how Microsoft Graph uses throttling to maintain service health and how address this feature when creating applications.

This module is also published as a Microsoft Learn module: Optimize Network Traffic with Microsoft Graph

Lab - Optimize Network Traffic with Microsoft Graph

The lab for this module is available in multiple units within the associated Microsoft Learn module. Use the following links to jump to the specific unit. Each Microsoft Learn unit represents a different lab exercise & demo in the presentation.

1. Exercise: Understand throttling in Microsoft Graph

   In this exercise, you will create a new Azure AD web application registration using the Azure Active Directory admin center, a .NET Core console application and query the Microsoft Graph. You will issue many requests in parallel to trigger your requests to be throttled. This will allow you to see the response you will receive.

2. Exercise: Avoid throttling & implement throttling strategies

   In this exercise, you'll use the Azure AD application and .NET console application you previously created and modify them to demonstrate two strategies to account for throttling in your application. One strategy used the HttpClient object but required you to implement the detect, delay and retry logic yourself when requests were throttled. The other strategy used the Microsoft Graph SDKs included support for handling this same scenario.

3. Exercise: Eliminate polling Microsoft Graph with delta query

   In this exercise, you'll use the Graph Explorer to create and issue a single request that contains multiple child requests. This batching of requests enables developers to submit multiple requests in a single round-trip request to Microsoft Graph, creating more optimized queries.
