Keynote: From Outage To Observability: Lessons From a Kubernetes Meltdown - Saiyam Pathak, LoftLabs & Arnab Chatterjee, Nomura
Thursday August 7, 2025 9:37am - 9:47am IST
Hall 3
Is basic monitoring and logging using prometheus and ELK stack enough? Our DevOps automation platform suffered a major Kubernetes outage due to weak observability despite having the basic setup in place.

What Went Wrong?
Our "good enough" setup fell apart when it mattered most. Logs were a mess with no correlation, & tracing was half-baked, leaving us clueless during debugging. One customer’s CI/CD pipeline overwhelmed shared resources and brought everyone down. Aggressive autoscaling overloaded the control plane. Worst of all, a single tenant’s failure affected the entire cluster.

How did we fix it?
We swapped basic Prometheus for a distributed setup that could handle the scale. Workloads got isolated per tenant and team, with multi-tenancy baked in and dedicated monitoring to match. Fine-grained autoscaling & experimentation with tracing tools(Parca/Odigos). The result? A cluster that bends but doesn’t break.

If you want to avoid your own outage horror story, this talk is for you.
