Developing microservice applications with Dapr
summary
Dapr provides language-agnostic building blocks (service invocation, state, pub/sub, bindings, observability) via a local sidecar that the app talks to over HTTP/gRPC, and sidecars communicate gRPC for discovery and TLS. Demo uses .NET SDK with three services (web, order API, warehouse), swaps the default state store: Redis/Cosmos DB by dropping a YAML component, publishes events (pub/sub) and sends an SMS via Twilio binding that works with one line of code. Local runs use the Dapr CLI/VS Code integration and production runs on Kubernetes or Azure Container Apps using the same components; tracing appears in Zipkin.
