Learn from production

• Our Kubernetes Cluster Was Costing $14,850/Month. We Moved to Fly.io for $680.

  Aditya Suryawanshi

  This is a war story about a 3-person startup that replaced a $14,850/month over-engineered Kubernetes setup on AWS with Fly.io for $680, cutting P99 latency from 320ms to 180ms and deploy time from 8 minutes to 45 seconds.

• Two Production Incidents That Taught Me More Than Any Course

  Ejiroghene Laurel Dafe

  This case study shows how one engineer resolved two real Kubernetes production incidents involving an overly aggressive Ingress rate limit and Istio breaking non-HTTP socket traffic.

• In-place PVC re-binding: zero-downtime disk migration on Kubernetes

  Maxim Nazarenko

  This case study explains how to migrate bound Kubernetes volumes from deprecated in-tree Azure Disk provisioning to CSI with in-place PVC re-binding, minimal restarts, and no data loss across production disks.

• Simplifying Model Serving with Kubernetes and Ray: Inside DoubleVerify’s ML Platform

  DV Engineering

  This case study shows how DoubleVerify built a Kubernetes and Ray serving platform to deploy and scale ML models in production.

  It also covers RayService wrapped with Helm, fault tolerance with external Redis, and platform gains like 30% lower GPU cost.
