Recent Knowledge Stream
- JournalFirst scale-to-zero verification on Azure Container Apps
Deployment log for the first verified scale-to-zero run on Azure Container Apps: zero replicas overnight, KEDA-triggered warm-up on the first request, and the cold-start latency budget observed before and after.
- ADRAzure Container Apps with Scale-to-Zero for Cloud-Native Microservices
Adopt Azure Container Apps scale-to-zero as the standard deployment posture for background workers and non-critical APIs: minimum replicas of zero, HTTP-triggered scaling for APIs, and event-driven KEDA triggers for queue workers.
- JournalRedis idempotency keys — tuning the reconciliation retry storm
Post-mortem on a retry storm that pushed 12 duplicate outbox deliveries through Redis: the TTL mismatch, the idempotency-key fix, and the monitoring gap that hid it for three hours.
