It has to be evaluated for speed, stability, and scalability under varying load conditions. It cannot go live without addressing any issues related to poor usability, system failure, functional discrepancies, and much more.<\/p>\n<p>In short, any inadequacy in performance testing can lead to issues post the launch.<\/p>\n<h3>Key Characteristics of Cloud<\/h3>\n<p>Cloud services are being leveraged by enterprises for their intrinsic benefits and features, which represent its strengths. A key aspect to consider is reduction in costs, which entails conversion of capital expenditure to operational expenditure. Cost effectiveness depends on two factors; the number of activities and the infrastructure made available. Moreover, there is low maintenance of Cloud computing application, which further reduces the efforts.<\/p>\n<p>Additionally, the performance of the application is constantly monitored and the web services are leveraged to develop loosely designed architectures. Cloud services help to further boost productivity, which enables multiple users to work on the same database at a given point of time. This helps in saving time and deliver within stringent timelines.<\/p>\n<p>Resources are made readily available in a Cloud set-up when compared to a non-Cloud environment. These resources are external and can be made available on demand. This makes Cloud Computing more reliable and efficient for enterprises who might need rapid availability of infrastructure for testing or development.<\/p>\n<h3>Performance Testing in a Cloud Environment<\/h3>\n<p>Testing in a Cloud environment is very much similar to testing in a non-cloud set-up. It involves a range of tests that help teams to analyze various aspects of the system. There are various Cloud adoption scenarios \u2013 public, private, or hybrid. Performance Testing evaluates the application\/software for various issues that need to get fixed. The difference comes in while planning and executing performance tests on the Cloud, as there are performance tests that are not so applicable in a Cloud set-up. Most importantly, the response time in a Cloud environment could differ from the time taken in a non-Cloud environment.<\/p>\n<p>Cloud services are implemented in various forms \u2013 Public, Private, and Hybrid. These are some important tests that development teams must consider in a Cloud set-up and as a part of the Performance Testing strategy.<\/p>\n<ul>\n<li><strong>Get Statistics on the Load<\/strong><\/li>\n<\/ul>\n<p>While the testing process begins, it is critical to get the required information from the Cloud provider on the load statistics from other customers sharing the Cloud. This will provide key inputs on the kind of response time that you can expect, considering there will be other applications hosted on the Cloud. Hence, it is recommended to run the tests when the load is high and evaluate the response time.<\/p>\n<p>These tests need to run regularly to note the minimum response time, maximum response time, and the average response time. It will help during the actual testing process and keep a track on the application\u2019s response time.<\/p>\n<ul>\n<li><strong>Conduct Stress Test<\/strong><\/li>\n<\/ul>\n<p>Similar to the load test, it is essential to conduct stress test in the public Cloud, where extreme planning and execution has to be done. Public Cloud is shared by multiple users, so testing has to be planned effectively as compared to a private cloud where the space is exclusively available. Stress test is critical for all the applications and understanding its behaviour during pressure points and breaking points.<\/p>\n<ul>\n<li><strong>Monitoring the Memory<\/strong><\/li>\n<\/ul>\n<p>With memory monitoring tools, volume tests can be conducted, where the testing team can monitor the virtual memory. This is essential for understanding the capacity and scalability of the virtual environment for testing the application. There are various tools that can be implemented to measure the same.<\/p>\n<ul>\n<li><strong>Check for Elasticity and Scalability<\/strong><\/li>\n<\/ul>\n<p>Elasticity testing is absolutely essential in a Cloud set-up to understand whether the performance is in line with the defined SLAs and can get further scalable up to an expected level. In a Cloud set-up where the model is more or less pay-per-use, elasticity testing helps to validate the quantum of services used and estimate the costs against the usage. This approach involves stressing the load to cut through the breaking point, where the load can be increased and decreased. For such cases the boundary value analysis method comes handy, which can help to determine the threshold.<\/p>\n<h2>In Conclusion<\/h2>\n<p>Cost effectiveness, speed, agility, and efficiency are some key reasons why enterprises are leveraging the Cloud extensively. Performance testing is a complex task that needs to be effectively customized for various applications\/projects. There are various factors that have to be considered while building the strategy \u2013 project environments, business drivers, acceptance factors, technology stack, available skill sets, resources, and approaches.<\/p>\n<p>In the Cloud set-up, the environment has to be checked for conduciveness and load for testing the application\u2019s performance. There are different implications of testing on a public cloud as against a private cloud. The Cloud can give the results, provided the strategy is very much intact.<\/p>\n<p>Cigniti\u2019s <a href=\"https:\/\/www.cigniti.com\/performance-testing\/\">performance testing<\/a> covers performance engineering, including capacity planning, baseline test, load, stress, endurance and benchmarking against competitors, production monitoring and consulting.
