Today, every business wants high-performing and high-quality software. But usually, it is seen that most of the applications fail to deliver expected performance under peak load or fluctuating network conditions. What Is Performance Testing? Today, let's learn more about this testing type in depth.

In case of a spike in traffic, you can automatically spin up more resources, often in a matter of seconds. Likewise, you can scale down when your application experiences decreased traffic. For example, as traffic increases, costs will too. Improved performance and availability. Inconsistent performance.
