Migrated 200+ bare-metal servers to Kubernetes in 6 weeks with zero downtime.

Starting Point

Where it began

200+ bare-metal servers across three data centers, manual deployments, and a monitoring stack built on SSH alerts forwarded to email.

The Challenge

What was in the way

A single server failure during peak season caused a 14-hour outage. Infrastructure teams spent 70% of their time on maintenance instead of new features, and scaling required hardware orders weeks in advance.

Our Approach

The strategy

• Map workloads and dependencies across the fleet.
• Containerise services in dependency order.
• Stand up Kubernetes with staging parallel runs.
• Add CI/CD with automated rollback gates.
• Deploy Prometheus, Grafana, and OpenTelemetry observability.
• Cut over incrementally with zero unplanned downtime.

The Solution

What we built

We containerised workloads with Docker, orchestrated them on Kubernetes, and built CI/CD pipelines with automated rollback gates. The migration ran incrementally with parallel runs proving stability before cutover.

Customer Experience

What changed for the customer

Customers experienced no downtime during the migration. Post-migration, deployments became routine and the platform stopped failing at the worst possible moments.
