Performance Engineering in the Real World: A Reality Check for Enterprises
The article discusses the disparity in performance engineering practices between MAANG companies and other enterprises. While MAANG treats performance as integral to development, many non-tech organizations see it merely as an afterthought. The piece emphasizes the importance of cultural shifts toward proactive performance engagement, moving from reactive fixes to embedded practices throughout the project lifecycle.

Performance Engineering
Discover the real difference between performance testing and performance engineering. From Connie Smith’s definition to practical SDLC integration and detailed comparison tables, learn why performance engineering is a proactive discipline embedded across the software lifecycle.
-
Functional vs Non functional testing
Functional testing ensures that software behaves as specified, validating features and workflows, while non-functional testing evaluates the system’s performance, reliability, and security. Both types are crucial for delivering quality applications, with functional testing focusing on correctness and non-functional testing addressing user satisfaction and system behavior under varying conditions.

So, what is performance testing?
Performance testing ensures that an application remains fast, stable, and reliable under various loads. It simulates real-world usage to evaluate speed, responsiveness, and scalability, identifying bottlenecks and ensuring optimal performance. This non-functional testing practice reassures developers and stakeholders that the application will perform well in production, meeting essential benchmarks.

Common Misconceptions About Performance Testing
Performance testing misconceptions include beliefs that it’s only for large applications, that functional tests suffice, and that lower environments replicate production conditions. It’s cost-effective compared to potential losses from outages. Performance testing encompasses stability and scalability, should occur throughout development, and involves various testing types beyond load testing to ensure comprehensive system evaluation.
