Production Use Cases

A retail platform operated 85 worker nodes and 220 production Deployments across three zones. Monthly node image upgrades repeatedly caused 30-60 second checkout brownouts.

A Series-C fintech company processing 12,000 transactions/second across 47 microservices on EKS in us-east-1. A failed deployment during peak hours caused a 4-minute checkout outage costing $380K in lost revenue. The CTO mandated zero-downtime deployments for all tier-1 services within 30 days.

A B2B payments processor handling settlement batches for 2,200 enterprise clients on GKE. Every weekday at 16:00 UTC, settlement windows trigger a 15x traffic spike from 800 req/s to 12,000 req/s within 2 minutes. The team had 3 baseline pods and needed to scale to 50 pods before the spike overwhelmed the service.

A SaaS observability platform onboarding 340 enterprise clients onto a shared EKS cluster with 120 nodes across 3 availability zones. Each tenant ran data-ingestion pipelines and Grafana dashboards. A noisy-neighbor incident where one tenant's runaway query consumed 80% of cluster CPU impacted 12 other tenants' dashboards, violating SLA agreements.

A healthcare data platform running HIPAA-compliant workloads on EKS in us-east-1 (primary) and us-west-2 (DR). The platform managed patient records for 1,400 hospitals and required RPO of 15 minutes and RTO of 5 minutes per compliance requirements. A us-east-1 regional S3 outage in March 2026 rendered the primary cluster inaccessible for 47 minutes.

An e-commerce platform with a 2.3TB PostgreSQL 14 database serving 4,800 req/s on AKS. The database needed upgrading to PostgreSQL 16 for performance improvements (parallel vacuum, I/O optimizations) required to handle Black Friday traffic projections. The team had a 4-hour maintenance window on a Sunday night but could not afford data loss or extended downtime for a database serving order management.

A real-time bidding platform processing 180,000 requests/second across 800 pods on a bare-metal Kubernetes cluster with 45 nodes. The ad-auction service had a strict 10ms p99 latency SLA for bid responses. iptables-based kube-proxy with 2,400 Services created 47,000 iptables rules, adding 3.2ms of kernel-space overhead per packet.
