Resilience Testing Is Non-Negotiable in the Enterprise SDLC

Resilience testing is a critical, continuous practice in the Software Development Life Cycle (SDLC) for distributed systems, as outages are inevitable even with the most reliable cloud providers. Uma Mukkara, Head of Resilience Testing at Harness, emphasized that resilience should not be viewed as a "day-two problem" but rather integrated into the SDLC alongside functional and performance testing to continuously verify system behavior across system failures, load conditions, and disasters. Delaying resilience validation leads to "resilience debt," which accumulates risks and increases business impact when failures occur. A holistic approach to resilience testing, combining chaos engineering, load testing, and disaster recovery testing, alongside cross-team collaboration and AI-driven insights, enhances system reliability. Harness has developed a unified platform for resilience testing, providing a comprehensive view to identify and address resilience risks, ensuring that resilience becomes a core discipline of modern software delivery.
