Sally Wahba StaffPlus London 2023
summary
Claims that old design decisions persist: the write-anywhere file layout still delivers near-free snapshots decades later, and incompatible early choices force returning HTTP 503 for throttling to preserve clients. Migrations take far longer than predicted — a cluster migration stretches to 12 years to migrate — and assimilating five observability acquisitions remains unfinished after five years. Concrete wins: adopting a new branching strategy and CI + branching cuts release cadence from 24 months to 18 then to six months; OpenTelemetry becomes the prioritized modernization.
