Performance and load testing of services may be performed under the supervision of both the development team and their client. What are the steps to performance and load test the SLA agreements? For example, a mobile app may be required to be available 100% of the time, whereas a web application may only need to be available 99.9% of the time. The required availability of the application is also dependent on the type of software being tested (e.g., percent of time the software must be available, maximum allowable downtime). In comparison, a web application may be expected to handle hundreds of concurrent users with the majority of transactions completing in less than 2 seconds. For example, a mobile app may be expected to handle hundreds of concurrent users with the majority of transactions completing in less than 10 seconds. The expected load varies depending on what kind of application is being tested (e.g., CPU utilization, memory usage, transaction volume). Testing methodologies may include functional testing, regression testing, and load testing. For example, mobile applications typically require different testing methods than web applications. Testing will vary depending on the type of software being tested. ![]() These 3 parts are described below: Type of software being tested : The SLA for Performance and Load Testing typically consists of 3 parts: type of software being tested, expected load on the application, and required availability. Testing of the service, and software in general, is often a significant part of verifying any Service Level Agreement (SLA). SLA Testing Factors to help determine application readiness These tests are used to determine the impact of new features on an application’s performance, identify bugs that may cause error conditions, and to determine the readiness of an application for use by end-users. Most Software Quality Assurance (SQA) teams are required to test the performance of applications that are under development. How do you create a Performance and Load Testing SLA Plan? With all that said, be sure to tailor your performance SLAs to meet the needs of your customers. Identifying your application’s performance SLAs will not only make sure you’re on track with your product, but it will also maintain user trust in your product. Should this happen, your day would go from bad to worse. To make matters even worse, if you went too far you could inadvertently cause a DDoS attach, which is illegal. Too many virtual users may cause their applications to fail, alerting their IT department and potentially resulting in a blocked IP Address. However, be cautious not to go overboard. You can check their page speed in an easy, non-invasive manner by running a free speed test against their site to gain insights in their performance metrics. Other teams may prefer to define their own, but benchmarking against 3rd parties is a perfectly acceptable method as well. One way to accomplish that is by beating the competition, therefore it is imperative to take a look at the competitors’ metrics. Look to Your CompetitionĪs developers, we should strive to make our products the best out there. Another avenue of gaining this information is to examine marketing/SEO agencies as they regularly publish industry data. Industry BenchmarksĪ quick Google Search can yield performance metrics your industry is using. Because they’ve already traveled that road before, they’re intimately familiar with what’s possible and what is realistic. Obviously, utilizing your own teams to define your SLAs is the simplest and most convenient technique. The three best places to obtain SLA expectations are from internal teams, industry benchmarks, and from your competition. Thankfully, there are multiple places to get inspiration from on defining performance SLA parameters. ![]() You must set appropriate performance SLAs to meet your user’s expectations. ![]() Web performance is increasingly important for both your user experience and your bottom line as users abandon sites after a few seconds. How can you define Baseline Performance Metrics? A development team can use metrics, thresholds, and expected performance to measure their own success. A development team can use SLAs with their clients to set clear expectations regarding the software they create and provide a framework for measuring their performance. SLAs are important to development teams because they provide a baseline standard for performance and operational quality. 7 Conclusion What is a Software Service Level Agreement?Ī software service level agreement is an agreement between a client and a service provider that specifies the level of support to be provided with regards to availability, performance, and other quality-related metrics.
