Performance Engineering: A New Approach to Scale the Project Quality

Failures can lead to large losses, so the best solution is to prevent them. Performance design allows for speed and efficiency, which is why we recommend implementing it in your projects.

Let's take a closer look at what software performance engineering is and how to apply it.

What is Performance Engineering?

Performance engineering is preventive continuous testing and monitoring of application performance. This ensures clear communication between all teams, as well as adequate use of tools and application of processes. This involves testers, business analysts, developers, and even product owners.

In performance engineering, all the actors are important, since everyone has a role to play. For example, a developer can usually only think about hardware and performance engineering software elements, such as bandwidth. But performance engineering goes much deeper than that.

Distributed applications are composed of several complex modules. Its mission is to provide users with high response times. The job of performance engineers is to test the stability of specific solutions. Such tests show the deficiencies of the system and refer them to specialists for elimination.

Greater flexibility and the creation of a stable base for process automation are the main advantages of using the technique.

From Performance Testing to Performance Engineering

While there are several similarities between performance engineering and performance testing, there are some significant differences. In particular, this concerns how the corresponding tasks are developed and analyzed.

When testing the product, the execution time of the request is analyzed. If problems are found, they are handed over to engineers for solution. In turn, the engineer can identify performance issues with a deep knowledge of scalable web architecture.

Other differences between performance design and performance testing include:

Testing simulates different loads on the system so that the application can run under different conditions. The design is aimed at creating a high performance, scalable and completely secure application using SDLC.

Testing allows you to find problems and submit them for solution by specialists. The engineers themselves are working to create a reliable scalable system with a clear architecture.

Testing involves the use of testing tools, and engineering relies on product development best practices.

Testing can use cloud-based tools, and engineering necessarily requires knowledge of programming and project methodologies.

Why You Need Performance Engineering

Developing a successful project is not only good code, but many other things to consider. Performance Engineering aims to address all of these issues. Let's consider its main advantages for any project:

1. Reliable and stable UX: everything will be optimized and have high performance.
2. Reduced system and hardware costs: All problems are identified early in the development phase.
3. High resilience in dynamic digital landscapes: It is important to validate the resilience of applications before launch.
4. Thus, performance engineering is an important and necessary component of any project aimed at success.

Adding Performance to the CI/CD Pipeline

There are some basic guidelines for adding performance to a CI / CD pipeline. Let's consider them.

1. Early testing

It is not very rational to conduct testing at the end of the pipeline, besides, you can create additional work for the whole team by rolling back the process. testing should be carried out continuously from an early stage. You can even run it in parallel with automated unit tests.

 2. Test automation

Automating the load testing process will put testing right in front of the CI environment. This will save you from releasing a quality development.

3. Setting landmarks

For the automation to work correctly, you need parameters with which you can compare indicators in the future. You must understand the baseline performance and the minimum acceptable performance standards.

4. Only test samples of the application

It is best to start testing with the most problematic parts of the application. In the early stages of development, there is no need to test the entire application completely.

5. Introduction of mandatory reporting

Generating consistent, complete reports is an important part of improving a project. This makes it easier to track compliance, performance, and even server load. Reporting also allows vulnerabilities to be identified early.

Agile Principles for Performance Evaluation

Agile integration is a common practice on a variety of projects. And the main reason for this is the high quality of the final product. Using Agile principles also allows teams to have tighter control over their project.

Constant testing, understanding the tasks for each sprint, collaboration within the team - all this gives excellent results. The risk of errors and omissions at all stages is reduced. Among the basic tenets of Agile is customer satisfaction.

Agile focuses on achieving small goals for the sake of big. Agile development principles also support team morale by motivating people to accomplish and improve work quality.

Top 7 Performance Engineering Techniques That Work

Performance and stress tests provide a ton of data for further analysis. There are also a number of quality and performance markers that allow you to use data more efficiently, including:

1. Identify tier-based engineering transactions
2. Controlled KPIs;
3. Reduce the number of analyzed transactions;
4. Wait for the test to complete before analysis;
5. Ensure reproducibility of results;
6. Increase the load;
7. Use visualization to spot anomalies.

Thus, performance engineering is based on the software development lifecycle and helps to create a product that meets business goals.

Performance Engineering Best Practices

Performance engineers make a great contribution to the quality of the finished product. They build connections within the team and understand which tools and techniques are more relevant in this case.

Consider the best practices for applying performance engineering:

1. Smart use of caching. The choice of the correct caching system is of great importance for the correct operation of the product.
2. Minimization of requests to the server. This results in savings and efficiency in the use of time, for example, when performing operations.
3. A careful attitude to memory. This also applies to network connections and database calls, everything must be foreseen.
4. Asynchronous processing. Reduce your workload using this method.
5. Performance Audit. This will help you avoid sudden interruptions and accelerate progress.

Performance engineering is a reliable way to improve the performance quality of your product.

Conclusions

Thus, the main task of a performance project is to find and eliminate the reasons that can interfere with scaling and work. In this case, the work will not be considered complete until the intended goals are achieved.

Whether you're stress testing each build, or deploying a new app or feature in it, all of this carries risks. The use of performance engineering allows you to minimize them at the initial stages, presenting the client with high-quality working performance engineering products adapted to further scaling.
