Case Study: Vonage achieves cost-effective CI performance testing with Grafana k6 and GitHub Actions

How to build performance tests into your CI pipeline with k6, GitHub Actions, and Grafana

Vonage, a communications technology company, wanted to shift performance testing earlier in development and build it directly into its CI/CD workflow. Using Grafana’s open source load testing tool k6 alongside GitHub Actions, the team aimed to catch performance issues sooner without adding major cost or complexity.

Grafana helped Vonage implement performance tests on every commit by deploying k6 in Kubernetes and visualizing results in Grafana Cloud dashboards. The setup provided clear metrics such as active virtual users, requests per second, and errors per second, plus trend views over time and by build number, enabling Vonage to track improvements and set practical thresholds for build validation.
