summary

Describes concrete operational practices used at FT and Skyscanner: migrated services onto Kubernetes to meet a 15-minute RTO, built active‑active US/UK stacks across ~180 microservices, use Kafka peaking at 2 million msgs/sec, implement automatic rollback in CI/CD, synthetic requests and structured event logs for probing production, idempotent processing, health/liveness probes, consumer restart-before-alert logic, chaos experiments and a Jenkins republish job so systems can limp to the next day instead of waking engineers at 3am.
