Nine teams were taking turns on one staging environment

Описание и применение

Много команд делили одну среду развертывания, что приводило к частым сбоям и затрудняло определение причин. Внедрение изолированных окружений на основе pull‑request уменьшило ошибки, ускорило отладку и снизило затраты до 300 £ в месяц.

Задача

A single shared staging environment caused frequent failures and attribution problems when multiple teams deployed changes, leading to costly manual debugging and slow release cycles.

Результат

Reduced staging failures, eliminated attribution ambiguity, cut manual debugging time, and lowered cost to £300/month while maintaining shared resources via locks.

Рабочий процесс

• Identify need for isolated environments
• Define environment in code (namespace, DB snapshot, stubs, hostname)
• Automate creation on PR creation
• Run soak tests for ~2 h
• Destroy environment on merge or after 12 h
• Use pipeline locks for shared resources
