A fintech company had 20+ production Kubernetes clusters running outdated versions (1.24-1.26), creating security vulnerabilities and compatibility issues. Manual upgrades took entire weekends with multiple rollbacks, service disruptions, and team burnout. They needed a way to safely upgrade to the latest versions without downtime.
Create new node pools with upgraded version, migrate workloads gradually, then drain old nodes. Zero impact on running services.
Test upgrades on staging clusters first, then canary production clusters (5% → 25% → 100%) with automatic rollback on failures.
Run comprehensive test suites on upgraded clusters: API compatibility, workload functionality, performance benchmarks, security scans.
Fully automated upgrade orchestration with pre-flight checks, sequential cluster upgrades, validation gates, and audit trails.
All upgrades completed without service disruption
From 48 hours to 4 hours per cluster
All 20+ clusters on K8s 1.30
Automated testing and validation
