What is Cloud-Based Performance Testing? 

Businesses are migrating towards a cloud-based framework due to multiple cloud computing benefits including cost-efficiency, ease of access, and scalability. Traditionally performance testing services always required big infrastructure and enormous resources. Further, as businesses grow more complex, it has become harder to maintain an in-house testing facility. Cloud computing has made software testing easier by making the availability of resources and infrastructure a lot easier and cost-effective. 

Why is cloud performance testing necessary? 

Cloud-based performance testing tests software using cloud infrastructure for functional and non-functional requirements. 

The main purpose of load testing services in the cloud is to measure key parameters including latency and system throughput. All this is done by changing parallel user numbers, operating the application with multiple load profiles and other performance metrics. Moreover, cloud also offers immense possibilities with no limitations within the budget. 

Cloud performance testing benefits 

Firstly, cloud performance testing comes with a lot of operational and end-result benefits. In addition, here are some worth noting benefits: 

More cost-efficient 

Companies need to invest enough hardware in simulating peak loads to perform onsite testing. Performance testing requires the maintenance of client and server infrastructures, deployment, tool purchase, and the creation of simulation scripts. 

Cloud testing eliminates these costs. A cloud service’s data centers provide ample computing power for testing, and you can scale the testing to suit your business’s needs. You just pay for the computing power and are not responsible for testing system maintenance. 

Detailed diagnostics 

Setup of cloud-based performance testing includes detailed analytics as part of the test package. Your in-house QA team can save a lot of time and effort with the testing scripts included. These diagnostics show your workers where and what the problem is. 

Simulating peak loads anytime 

You have the option to notify your cloud service provider before starting a performance test. Since the provider oversees the testing process to ramp up the resources if required, you can run the performance test anytime. It enables you to prevent diverting resources from important business operations to test before a marketing campaign or the holiday season. 

Global readiness 

Cloud-based testing setup can help you test applications for the international market. Businesses expanding into new markets or introducing products with worldwide sales potential can benefit without spending a bomb. 

Test multiple scenarios 

Testing should not just involve browser-based apps. You must be able to run tests that look at diverse ways of accessing your internal systems, such as mobile devices. Cloud testing gives you a complete picture of how the system performs for a wide range of users in various situations. 

Types of cloud-based performance testing 

Load test 

A load test may determine whether your system’s performance has hit its optimum using multiple users simultaneously. 

Stress test 

Firstly, how do you know if your communication system can handle hundreds or thousands of calls at a time? You will not know until you receive the maximum amount of intended traffic. Before a problem arises, stress testing uncovers bottlenecks and performance issues, enabling you to take immediate action. 

Latency test 

Latency tests determine how long it takes for data to move between cloud network points. 

Browser test 

This test is essential for determining if a browser works efficiently with the complete system or not. 

Targeted infrastructure test 

You can isolate or test each layer or component of an application for its ability to deliver the required performance in this test. Furthermore, the results of this test can help identify any problems that may be affecting the system’s overall efficiency and performance. 

Failover test 

As traffic and use rise, the system must summon more resources to maintain the end-user experience. 

Capacity test 

This test determines the maximum amount of loads a cloud system can handle. 

Soak test 

Soak testing assesses a system’s real-world performance by exposing it to heavy traffic for an extended period. 

How to build the right strategy for performance testing in the cloud? 

Cost-efficiency is one of the major benefits of the cloud. It also allows you to create different test regions to enable easy testing as per the requirement. Moreover, the right testing strategy should always focus on the reason behind migrating to the cloud including easy infrastructure access, cost savings, shorter time cycle and the choice of hybrid, private or public cloud, among others. 

The testing strategy should also identify the type of tests that need to be done on the cloud including the above-mentioned tests. In addition, all the risks related to cloud testing should be factored in before making the final call. Other parameters including test environment, testing tools, hardware, bandwidth, and software should be considered while devising a performance testing strategy in the cloud. 

You should analyze reliability, security, latency, quality, and bandwidth if you are leveraging the services of a third-party cloud vendor. Thus, for performance testing, it is typical to vary the user load with multiple load factors as per the defined test strategy. Furthermore, continuous monitoring and analysis of test results should be done in real-time to ensure performance enhancement in a shorter period. 


In conclusion, all good things are challenging, and so are cloud-based load testing services. Moving performance testing to the cloud can help businesses achieve greater reliability and scalability cost-efficiently. Lastly, cloud-based performance testing can enable testing teams to leverage resources instantly and mitigate the challenges of hardware and network infrastructure availability at scale.
