Flipkart has won the CNCF End User Case Study Contest after building a large-scale chaos engineering platform on Kubernetes and LitmusChaos, while contributing five enhancements back to the open-source project and planning further community releases.
Flipkart has won the CNCF End User Case Study Contest at KubeCon + CloudNativeCon India 2026 for building a large-scale chaos engineering platform powered by open-source Kubernetes and the CNCF incubating project LitmusChaos.
Beyond the award, the company’s most significant achievement is its contribution back to the open-source ecosystem. Flipkart’s Central Reliability Engineering (CRE) team returned five core fixes and enhancements to the upstream LitmusChaos project, addressing community challenges including database index issues, duplicate-name validation repairs, workflow configuration fixes for custom image registries, and other improvements.
“Resilience is table stakes for running microservices at scale,” said Chris Aniszczyk, CTO, CNCF. “Flipkart’s systematic practice with Kubernetes and LitmusChaos demonstrates how a vendor-neutral approach eliminates the guesswork of fault injection and hardens the open source foundation. Their five upstream contributions are the real win for community collaboration.”
The platform executes about 90% of infrastructure chaos experiments in Kubernetes staging environments before production deployment, helping harden microservices, validate observability frameworks and prepare systems for high-traffic festive sales.
To support operations at scale, Flipkart developed four major LitmusChaos extensions, including a hybrid multi-tenant architecture, a DaemonSet-based high-availability model, a Script Runner fault for dynamic target selection, and support for legacy virtual machine workloads.
“Winning the CNCF End User Case Study contest validates our team’s commitment to treating system outages as a standard, systematic procedure,” said Aditya Sridasyam, Software Development Engineer 2, Flipkart.
Looking ahead, Flipkart plans to open source its custom DaemonSet-based injection architecture and integrate automated chaos testing into CI/CD pipelines as a mandatory software development lifecycle phase.
