"Dapr Building Blocks: Sidecar-Driven Microservices Without Reinventing the Wheel"
Modern microservices often fail in the same predictable ways: fragile integrations, inconsistent resiliency, and operational blind spots that only appear under real load. This book targets experienced engineers and architects who are tired of rebuilding the same distributed-systems plumbing and want a rigorous, portable approach. It frames Dapr not as a convenience layer, but as a disciplined runtime contract—one that clarifies what belongs in application code, what belongs in the sidecar, and what belongs in the platform.
You'll learn to use Dapr's building blocks as stable interfaces with explicit semantics: state management with optimistic concurrency, idempotency, and transactional boundaries; pub/sub systems designed for at-least-once reality, dead-letter handling, and debuggable pipelines; and reliable service invocation with latency budgets, circuit breakers, and security boundaries. Deep coverage of component configuration, scoping, secrets, and "swap-the-backend" portability teaches you how to avoid environment drift and backend-specific traps while still embracing real-world constraints.
The emphasis is production readiness: identity and mTLS, observability that controls noise and cost, and versioning/upgrade playbooks that treat runtime and component changes as first-class risk. Expect protocol-level detail (HTTP vs gRPC), advanced edge patterns, and decision criteria throughout. Familiarity with microservice design, containers/Kubernetes, and cloud messaging/data stores is assu
