The Future of Performance Engineering
Performance is a key element of software systems. Hence, a successful software developer understands that writing bug-free code is not enough. Software developers are expected to create a holistic product that factors in security, user-friendliness, and scalability while also handling the complexity that comes with highly distributed applications. Hence, it is important to monitor app performance through every step of the development process.
Quick and early detection of potential performance-related issues can significantly enhance the quality of fixes and expedite the deliverability of the end-product. The demand for such skills has incorporated Performance Engineering as an essential part of software development.
What is Performance Engineering?
In simple terms, performance engineering relates to the techniques employed to ensure the software and its networks are capable of carrying out the functions assigned to them.
Considering that software applications are composed of various modules, performance engineers ensure that these components offer accurate and dynamic responses in accordance with their function. Further, conducting the test automation trends on the system allows the developers and designers to identify the system flaws, which can be used as a reference to find appropriate solutions.
Performance engineering also involves testing, securing, and optimizing the software when new and major changes are being incorporated in the application. These modifications could include switching to cloud solutions, moving to different mobile platforms, etc.
The 4 Ws of Performance Engineering
The current test automation trends capture the essence of performance engineering through the following questions:
Business requirements act as the primary driving factor behind performance engineering. Performance testing simulates how the system will perform under production load, and accordingly anticipates the issues that may crop up during heavy load scenarios. Thus, potential issues are identified in the early stages of software development and are addressed accordingly.
As the software goes down the production and developmental line, the cost of fixing the bug increases proportionately. Hence, performance testing is required for the early detection of performance issues.
Performance testing tools mimic the condition for the highest production load to locate performance bottlenecks. Performance engineers make use of effective techniques to optimize the software in order to boost software performance through every stage of the application development process.
Since one can understand that performance testing is a distinctive Quality Assurance process, it must occur once every round of development. It is a continuous process that prevails through the many phases of the development cycle, right from design to final QA phase.
Performance engineering involves dedicated certified professionals who can not only conduct the performance tests but also act upon the results. Since performance engineering is involved in every stage of product development, everyone – from designers to developers to QA testers – participates in performance engineering. Thus, it adds agile methodologies in the mix and ensures that when the product reaches the QA stage, it would already be in its optimized state.
Importance and Benefits of Performance Engineering
The greatest advantage of performance testing is that it identifies performance-related issues in the nascent stages of product development. Hence, time, money, and resources are efficiently used during the complete lifecycle. Accordingly, performance engineering facilitates rapid application delivery with minimum issues.
A few other benefits of performance engineering include:
- Cost efficiency and increased revenue
- Attractive return on investment
- Greater accuracy and resilience (the ability of software to jump back from failure)
- Better user experience and high-quality software production
- Assured customer satisfaction
- Reduced hardware and system costs
- A decrease in the cost of change involved with performance tuning
Performance Engineering: The Way Ahead
Everyone knows that nearly 50% of users are more likely to abandon an app if it fails to load within 3 seconds – this fact highlights the importance of optimizing software performance and the need for performance engineers.
Performance engineering allows for testing and automation trends that help deliver faster, efficient, and responsive systems that are capable of withstanding the customer expectations and the subsequent loads. It ensures that the product is delivered in the perfect manner in the very first attempt rather than working and reworking on the same project. Moreover, it fixes responsibility on every development team, be it designing, coding, QA testing, to ensure high performance in all circumstances.
The successful integration of performance engineering gives rise to an application that performs accurately and consistently as it has been optimized for best performance even in events of failure! Hence, needless to say, the demand for performance engineers is bound to increase drastically in the years to come!
