Initial situation

Infrastructure projects for industrial and service companies

Critical services ran on fragmented hosts without a unified resilience design. Maintenance required long outages, while recovery depended on manual actions by several specialists.

Engineer’s comment

The goal was not to replace individual servers but to remove hidden failure points. We built the migration from a dependency map and rehearsed recovery before switching production workloads.

Customer testimonial

The transition was completed without stopping production. We received both a new platform and clear operating procedures, with all critical services visible in one place.
