Azure Load Testing – Create Load Check for App Service Net Apps


On this article, we’ll delve into the method of making an Azure Load Testing Service and producing load on an present App Service—particularly, a Net App. Be a part of me in exploring the steps required to arrange and execute load assessments successfully to validate the optimum efficiency and reliability of your internet functions.

Whether or not you are a developer, a QA engineer, or an IT skilled, this tutorial supplies worthwhile insights and sensible steering that can assist you grasp the artwork of load testing in Azure.

Let’s get began.

Create Azure Load Check Service

Create an Azure Load Testing Service utilizing the beneath steps

Fundamentals Tab

  • Identify: Present the identify of the Azure Load Testing useful resource
  • Location: Select the Azure Knowledge Heart Area

Encryption Tab

  • Encryption Sort: MMK / CMK (Depart to Microsoft Managed Key – MMK).

All of the Load Testing Service artifacts are encrypted utilizing these Keys.

  • Optionally present Tags and Lastly overview all of the inputs and create the Azure Load Testing Useful resource.
  • As soon as the Azure Load Testing useful resource is created, we will begin creating the Assessments utilizing the beneath choices.

Azure Load Testing helps creating the beneath two kinds of assessments

  1. Http-based Check: Http-based assessments are based mostly on Http Endpoints. You possibly can create a Check with as much as 5 endpoints as of now by passing the required HTTP verbs, Headers, Physique, and different parameters which can be required to invoke the HTTP endpoint.
  2. JMeter Script-based Check: If you have already got JMeter scripts created/recorded for the Assessments, you may add them.JMX file (together with supporting information) to the Azure Load Testing Assessments and might run the JMeter scripts inside the Azure Load Testing useful resource.

In fact, you may also create a Check utilizing Azure DevOps CI/CD Pipelines & Github Actions as properly.

Azure Load Testing Pricing

Azure Load Testing useful resource pricing has two elements

  1. Load Testing Useful resource: It prices a flat 10$ per 30 days. The price additionally contains 50 Digital Consumer Hours (VUH) every month (VUH defined within the beneath part)
  2. VUH: Along with the fastened price, relying on the consumed variety of VUH, Azure prices 0.15$ for every extra VUH.

Digital Consumer Hours

In Azure Load Testing, VUH stands for Digital Consumer Hour. It is a unit of measurement used to quantify the load-testing assets consumed throughout a efficiency take a look at. Basically, one Digital Consumer Hour represents the usage of one digital consumer for one hour throughout the load take a look at. Azure Load Testing permits customers to simulate digital customers (VUs) to generate site visitors and stress take a look at internet functions. The variety of VUs and the length of the take a look at decide the entire Digital Consumer Hours consumed. This metric helps customers perceive and handle the price related to load testing in Azure.

Under is an instance of how the pricing works.

  • Variety of Customers (VUs): 50 customers
  • Length of Check: 10 minutes

Digital Consumer Hours (VUH) consumed = Variety of Digital Customers * Length

On this case, 50*10 = 500 minutes = 8.33 VUH roughly.

Azure prices 0.15$ per every VUH. In our case, it will price 8.33*0.15 = $1.24 roughly.

So, for a take a look at run for 50 Digital Customers for a length of 10 minutes, it will price lower than 2 USD.

Create a Check

Let’s now, create a easy HTTP Check within the Azure Load Testing service as proven beneath.


When you click on on Create a URL-based take a look at as proven within the above screenshot,

URL-based test

As proven within the above display seize, we create a primary URL-based take a look at (uncheck the Allow superior settings) and the beneath particulars.

  1. Present the identify of the take a look at
  2. Present the URL of the Net endpoint
  3. Present the variety of Digital Customers the Complete length of the take a look at and the Ramp-up time which defines the period of time it takes to create the digital customers.

As soon as all of the above inputs are offered, click on on Evaluation + Create to create the Check. After the take a look at is created, the Check run will probably be kicked off, the Load-tested brokers will probably be provisioned and the take a look at run in opposition to the endpoints will probably be initiated beneath is the way it takes care of the Check run is accomplished.

Notice. As we unchecked the Allow Superior settings checked, all the opposite tabs besides the Fundamentals turn into optionally available.

Enable Advanced settings

After two minutes (the length of the take a look at), the Check run was executed and the Check outcomes are proven within the above screenshot.


This text supplies steps for creating an Azure Load Testing Service and making a easy load take a look at on present App Providers, particularly Net Apps.

Key steps lined within the article embrace,

  • Creating an Azure Load Testing Service by specifying important particulars corresponding to identify, location, and encryption settings.
  • Exploring the 2 kinds of assessments supported by Azure Load Testing: HTTP-based assessments and JMeter Script-based assessments.
  • Understanding the pricing mannequin for Azure Load Testing, together with the fastened price for the Load Testing Useful resource and the extra price for Digital Consumer Hours (VUH).
  • Explaining Digital Consumer Hours (VUH) as a unit of measurement for load testing assets consumed throughout efficiency assessments, together with an in depth instance of VUH calculation and related pricing.
  • Demonstrating the method of making a easy HTTP-based take a look at within the Azure Load Testing service, together with specifying take a look at parameters and reviewing take a look at outcomes.
