Navigating Cloud Launch Risks
Performance testing strategy done right
Before launching a new suite of cloud-based applications, our client wanted to be sure their systems would hold up under real-world pressure. We helped them design and run a targeted performance testing strategy — identifying key risks, fixing them early, and ensuring a stable, high-performing launch.

Testing metrics and goals
- Defined performance testing metrics tailored to client's goals
- Objectives focused on ensuring optimal software and infrastructure performance
- Metrics included response rates, error/failure rates, and throughput benchmarks
Tools and techniques
- Utilized industry-leading tools such as JMeter, Google Lighthouse, and Azure Monitor
- Conducted capacity, stress, capability, endurance, and web performance tests
- Integrated performance testing seamlessly into the DevOps pipeline for continuous monitoring
Optimization insights
- Provided insights into optimization opportunities across cloud resources
- Identified and addressed scalability limitations through load testing
- Recommended adjustments to infrastructure and application configurations for improved performance
The Challenge
Uncertainty before launch
Moving to the cloud gave the client flexibility and scale, but also introduced new unknowns. Would the apps handle real user traffic? Would performance hold steady under stress? The development team had worked hard on functionality, but without clear data on performance, there was a risk of crashes, slowdowns, and poor user experience after launch.
The client needed a way to test how their software and infrastructure would behave before going live — and avoid the cost and pressure of fixing problems too late.
The Solution
Focused testing for cloud and app readiness
We developed a tailored performance testing plan focused on two areas: how well the applications performed, and how well the cloud infrastructure could support them under load.
We began by identifying key metrics — like response time, error rates, and throughput — and testing them across different scenarios. Using tools such as JMeter, Google Lighthouse, and Azure Monitor, we ran a series of tests:
- Capacity tests to see how much the system could handle
- Stress and endurance tests to simulate traffic spikes and long usage periods
- Web performance tests to analyze front-end experience
All of this was integrated into the client’s DevOps pipeline to enable fast feedback and ongoing monitoring.
We also analyzed the test results to provide specific recommendations:
- Where cloud settings needed tuning
- Which parts of the application architecture required optimization
- How to adjust configurations for better scalability
The Impact
Catching problems before they happen
The first round of testing surfaced performance issues that hadn’t been caught during development - including bottlenecks under load that would have affected user experience.
By identifying and resolving these issues early, the client avoided the risk of a poor launch. They deployed their apps with confidence, knowing their systems had been tested under real-world conditions.
Thanks to this process, the development team also gained better visibility into how their applications behaved in the cloud - which will support future releases and ongoing improvements.
