Saudi Aramco needed an internal equipment-reservation system: departments reserve equipment, use it, and return it by a deadline so the next department can book it. It had to be delivered on a hard timeline as the condition for onboarding them onto the platform.

A third-party device server that streams telemetry from the fleet was moving to a new cloud version. The change repointed writes from the existing location/alarm tables to new v2 tables. We ingest that data via CDC → Kafka, so the cutover risked dropped or duplicated pings across every device on the platform.
