Performance issues in your software systems happen every day, but typically not because of external factors. Instead, performance issues are built into the software by engineers who don’t realize there will be problems. Even IT professionals are humans and can make wrong assumptions when they code. That is why performance engineering of software systems is important.
How can your team overcome some of the assumptions we all make when coding? Performance in software engineering help to ensure that your IT team is steady and straightforward as they code, allowing you to anticipate bottlenecks and potential problems.
Computer and software design has some of the same pitfalls as every other career – engineers tend to work on autopilot and do the same things over and over again. As technology advances and changes, some of those methods that once worked no longer do the same things. At the same time, we are maintaining and editing code that was designed to work with systems ten years ago. Just think about all the changes that have occurred on different platforms in the last ten years – web applications, mobile applications, and even customer savvy.
Your software systems need to meet the performance requirements of today’s world, regardless of when they were created. Sometimes, trying to keep up can fall by the wayside and reveal many, many problems.
So how can you solve the problems with software engineering? Classically, IT teams work through a QA process. That is too slow. By the time an application gets to the QA process, it is too late to go back and make significant changes. Your team has already invested time, effort, and funding into the design and development process. Waiting until the last minute to find a performance problem will delay the launch of the product.
You need to get applications and software systems right the first time you make them. By adopting performance software engineering, you can ensure that when an application gets to the QA process, there will be fewer changes to make. The changes that are found fit into an agile process, allowing realignment early on in the development process.
At the same time, performance engineering of software systems allows for the user to have the benefit of the system, even while changes are being made in the background. If a user reports a problem, they will get a sense that their concerns will be addressed quickly.
Developers are expected to perform at a very high level, but we all make mistakes. Still, our IT teams need to take the extra steps to ensure that when they finish writing code, it is getting tested automatically. At the same time, developers need to ensure that everything is performing as well as it should.
It is important to note that performance software engineering is more than just simple testing: it is complete, comprehensive monitoring of code throughout the lifespan of the application.
At the end of the day, performance engineering of software systems helps to simulate how a system will perform throughout its lifespan. Then, it checks for potential problems that may emerge when tested against traffic, load conditions, and business requirements. The goal is to reduce technical debt and provide better business value from the application by catching potential issues early on in the development cycle.
Remember: it costs more to fix a bug the further along in the lifecycle you are; catching a bug earlier helps to mitigate costs.
In the end, performance engineering produces two results:
As a result of performance software engineering, IT teams can focus more on quality development and mitigating any risk.
