Why You Need to ‘Shift Left’ Performance Testing

Accelerating digital business inevitably requires ongoing technology changes—increasing automation, shifting to cloud, embracing remote work. While these and other changes may be necessary, they also impact the performance of your hybrid IT infrastructure, from mainframe to cloud.

These impacts could be in the form of reduced processing speed, unstable computing environments, increased security vulnerabilities and more. If not prevented or resolved quickly, these translate to negative impacts on the experience your organization delivers to its own business end users and, more importantly, its customers.

That’s why performance testing is so important. And just as important is when you perform this testing in the software development life cycle.

Why Shift Left Performance Testing Matters

Increasing testing is an important part of ensuring you can do things with higher quality, velocity and efficiency. Shifting testing left enables DevOps teams to identify and prevent defects from snowballing into larger issues later in delivery.

The notion of shift left testing applies to more than catching bugs and improving code quality. The end goal is to deliver the highest level of value to your business and customers.

Therefore, shift left testing should also apply to the process of testing the health and performance of your hybrid IT infrastructure that manages the applications and data at the heart of digital value you deliver.

Shift left testing for system performance can help you catch issues that integration testing alone cannot. By stress testing your application, you gain insight into whether your production system will stand up to the impact of changes made to applications earlier in the software development life cycle. This ensures business end users and customers aren’t facing difficulties with what you deliver.

What Shift Left Performance Testing Looks Like

The operations team at one of ASG’s long-time customers, a major healthcare organization, shifted performance testing left by integrating ASG-TMON PA into their DevOps toolchain. This shortened testing cycles and the performance feedback loop, helping them accelerate their shift to an operations model of site reliability engineering, a method often paired with DevOps to improve the reliability and performance of infrastructure.
Using ASG-TMON PA, the operations team can provide feedback to Development about application and server-side performance across application releases. The operations team also uses ASG-TMON PA in their DevOps toolchain to help Development understand behavioral changes with the continuous deployment of weekly and monthly monitoring agents and scripts that support complex monitoring capabilities for the solutions they host and sell.

Make Shift Left Testing a Priority

Performance testing is an important aspect of delivering high-quality value to your business and customers. As your company accelerates digital transformation and embraces new business agility, shifting performance testing left in the software development life cycle will help you catch issues sooner than later, ensuring your IT systems remain stable to support your necessary technological shifts.
