What do you need to performance test before moving to cloud?

Performance testing is a type of software testing that evaluates how well a system performs under various conditions. It involves measuring and analyzing key performance indicators such as response time, throughput, and resource utilization to determine how well the system can handle the expected workload. Performance Testing is a non-functional testing measure used for testing the speed, response time, stability, reliability, scalability, and resource usage of a software application under expected workloads.

The goal of performance testing is to identify performance bottlenecks and ensure that the system meets its performance requirements. It is commonly used to test web applications, databases, and other types of software systems to ensure that they can handle the expected user traffic without crashing or slowing down.

There are many different types of Performance Testing

Load Testing checks the application’s ability to perform under anticipated user loads. 

For instance, an e-commerce website that experiences a high volume of user traffic during holiday seasons such as Christmas or Black Friday. Load testing can be performed to evaluate how well the website can handle the expected increase in user traffic during these peak seasons.

During load testing, many virtual users or simulated traffic is generated to mimic the expected user load during the holiday season. The performance of the website is then measured and analyzed to determine how well it can handle the load. Load testing may include measuring the response time of the website's pages, analyzing the server's resource utilization, and monitoring the website's availability during the peak traffic period.

Stress Testing involves testing an application under extreme workloads to identify the yield point of an application.

For instance, a mobile application that is widely used by travelers for navigation purposes. Stress testing can be performed to evaluate how well the application can handle low battery conditions when a user is in a remote area and unable to charge their device.

During stress testing, the battery of the mobile device is drained to a low level, and the application is run to evaluate its behavior and performance under these conditions. Stress testing may also involve simulating other extreme conditions such as poor network connectivity, low memory, or high CPU usage.

The performance of the application is measured and analyzed to identify any issues that may occur under such extreme conditions. The results can be used to optimize the application for better performance, ensure that it meets the expected performance requirements, and provide a better user experience for travelers in remote areas.

Endurance Testing is done to make sure the software can handle the expected load over a long period of time and to detect memory leaks.

Scalability testing is executed to determine the software application’s effectiveness in “scaling up” to support an increase in user load. It helps in Capacity Planning.

Fail-over/Reliability Testing objective is to check the performance of the application under server, network, application failure scenarios.

Spike Testing tests the software’s reaction to sudden large spikes in the load generated by users over a short period of time.

Volume Testing tests the overall software system’s behavior when a large amount of data is populated into the application database. The objective is to check software application’s performance under varying database volumes.

Performance Testing is an essential part of software testing that helps to ensure that a system performs well under expected workloads. It involves measuring and analyzing key performance indicators such as response time, throughput, and resource utilization to identify performance bottlenecks and ensure that the system meets its performance requirements. Each of the types of testing serves a different purpose and helps to identify potential issues in the system.
