Distributed Systems

Microservices & Event Schema Modeling

Design robust asynchronous message contracts, CloudEvents payloads, and synchronous inter-service communication standards.

Engagement Specifications

Distributed architectures frequently collapse due to brittle, undocumented message schemas. We design formal event contracts using AsyncAPI, CloudEvents, and Protocol Buffers to maintain strict domain segregation, reliable event sourcing, and consumer-driven contract testing.

Microservices & Event Schema Modeling
Contract Deliverables

Included Deliverables

  • AsyncAPI specifications for all domain event topics
  • Schema Registry evolution strategy (Avro / Protobuf / JSON Schema)
  • Dead-letter queue (DLQ) and poison-pill payload standard
  • Pact-compatible consumer-driven contract test blueprints
Architecture Phases

Execution Process

01. Event Storming & Schema Definition Map system state transitions to immutable domain event specifications.
02. Evolution & Compatibility Rules Set forward/backward schema compatibility modes and schema registry enforcement rules.
03. Integration Testing Blueprints Deliver automated verification harness for producer and consumer validation.

Who This Engagement Is For

Platform engineering teams adopting event-driven architecture, Kafka, RabbitMQ, or gRPC microservices.

✓ Guaranteed payload backward compatibility across decoupled microservices ✓ Clear message schema lineage and event catalog ✓ Prevents dead-letter queue crashes due to unannounced field changes
