## About this blog

Hey folks!, In tis blog we will see what are the pre-requisites to run performance testing in <a href="https://docs.microsoft.com/en-us/azure/load-testing/overview-what-is-azure-load-testing?wt.mc_id=loadtesting_ablogannounce1_blog_azuremktg">Azure Load Testing framework</a>.

-------------------
## Purpose of load testing

- In order to say that application is ready to move into production , we might need to know how it will perform in real user scenarios or how it will be affected by normal and peak loads.

- It allows us to identify the bottlenecks/defects in your architecture

- Azure Load Testing test engines abstract the required infrastructure for running a high-scale load test. 

- The test engines execute the Apache JMeter script to simulate a large number of virtual users simultaneously accessing your application endpoints.

- <b>Client-side metrics</b> <br/>
It allows us to visualize the request/response time and the number of requests per seconds for a specific number of virtual users.

- <b>Server-side metrics</b><br/>
It allows us to integrate natively with azure monitor, including application insights and container insights to capture details from azure services. Each metrics depends on the type of service you intend to analyze.
