Load Testing Azure WebApps from Microsoft Azure Portal

I am excited to share about a great feature added to Azure Web Applications experience in Azure Portal, which is the capability to do Load Testing of the web application right from the Azure Portal. There is a detailed blog post on Visual Studio MSDN Blogs about this announcement – Announcing Public Preview for Performance/Load Testing of Azure WebApp. Similar announcement on the Azure blog – Public Preview of Performance Test on Web and Mobile App.

Here are two videos on the topic on Channel9 (Do watch them):

  1. Azure Friday Video on Performance Testing Web Apps
  2. And follow up video on doing Advanced scenarios from Visual Studio Enterprise

I know what you are feeling, the experience and the User Interface looks just brilliant, right?. Yes, Its brilliant. There has been a great effort behind it building this experience :). There were good challenges and great great learning as well.

And I do think you would be interested in understanding how is the new Azure Portal being built. There is a very good blog from Justin Beckwith which explains this stuff perfectly – Under the hood of the new Azure Portal. I recommend this as a must read blog to know about the new portal. Make sure you watch Steve Sanderson video as well, its really cool.

Please do try out the new feature and share your valuable feedback.

Question and Answers.

Question: How to use an existing Visual Studio Online account work with the new Load/Performance Test Experience in Azure Portal?

Answer: Your Visual Studio account should AAD backed. To know if you account is AAD back you can go to the account settings and figure if it AAD backed. Else you can follow the link provided there 

There is a blog post which should make things easy: Link Visual Studio Account to Azure

Question: [A very very rare scenario] I am facing issue setting an account like mentioned below. How to unblock my self?


Answer: You shouldn’t be seeing this at all. But there is a very negligible chance you might face this. In such cases, you can click on the gear button at the top right corner of the Azure Portal that takes you to the “Portal Settings”. Here you can click on the “Discard modifications” button and things should start work.



The impact of this change is that it would clear any user settings in the Azure Portal like the pinned tiles on the home page will be cleared and specific user settings that are customized would be reverted and portal would be started afresh. Please note that it would not clear any application data.

Cloud load testing with Visual Studio Online

This post has been long delayed from me. I have been working on Cloud Load Testing (CLT) with Visual Studio Online (VSO) for close to an year and half and it has been a great learning curve. Got an opportunity to work on various areas like Scalability, building frameworks to understand the service usage, integrating with other VSO services, building service dashboard and making my hands dirty building UI. A fun ride. A really proud thing is that this product is completely built ground up in Microsoft IDC, Hyderabad.

Cloud Load Testing Service in short:

The service will greatly reduce the amount of work required in setting up the infra-structure for load testing an application, configuring it with right settings and maintaining the environment.With CLT in place, the service will take care of setting up the agents, deploying your tests, and running your tests automatically, so you can just focus on what matters the most – finding and fixing performance and scale related problems in your application.

I am going to point to a series of good links to explore about CLT

1. Super Simple Load Test Trial Experience announced by Brian Harry – With this announcement customers can do a Load Test from Visual Studio Online (visualstudio.com).This experience is visible as of today to only users with MSDN Ultimate License. In case you don’t have an Ultimate license you still get a view of the experience from this Channel 9 Video demo’d by Chuck – Load Testing Made Easier

2. Brian Harry announcing about CLT – We all watched this demo with lot of excitement 🙂

3. Load Test your App – MSDN Article

4. CLT General Availability note 🙂

– This link has various links to getting started docs

– With the release of GA, customers can monitoring metrics from their Applications under test using Application Insights and quickly troubleshoot any performance issues.

5. Link to a good video

You get 15000 VUser minutes if you have an account on VSO. Do try out and share your feedback.
