Developing microservices like a boss with Dapr and Azure Container Apps
summary
Dapr plus Azure Container Apps run a three-component demo (web, API, processor) deployed with Bicep and GitHub Actions, using Dapr sidecars for service invocation, Cosmos/Redis state stores and Azure Service Bus pub/sub. Revisions enable blue‑green and A/B traffic splits and the pipeline creates a staging revision, runs tests, then swaps traffic. Scaling uses KEDA rules to go from 0 to 10 replicas driven by Service Bus queue length (>1) and successfully processes messages before scaling back to zero.
