Have you worked with microservices architecture? If yes, how many years of experience do you have?
MicroservicesArchitectureCloud
✅ Yes — I have worked with microservices architecture for 6+ years, and with service-oriented/distributed integration for considerably longer.
Technical detail
- 🧩 Decomposition — bounded contexts and business capabilities as service boundaries, data ownership per service (no shared database), explicit public contracts, and pragmatism about granularity (avoiding distributed monoliths).
- 🏗️ Delivery patterns — API gateways, BFF layers, service-to-service REST/gRPC calls, asynchronous events for cross-context flows, CQRS where read/write profiles differ, and the saga/outbox combination for consistency.
- ☁️ Platform and operations — containerised services (Docker) orchestrated with Kubernetes/ECS/AKS, per-service CI/CD pipelines, configuration and secret management, autoscaling and health probes, centralised logging, metrics and distributed tracing with alerting.
- 🛡️ Reliability and security — timeouts, retries with backoff, circuit breakers, bulkheads, DLQs, idempotent handlers, zero-trust service authentication (OAuth2 client credentials/mTLS), least-privilege IAM and secrets rotation.
- 🧪 Quality — contract tests, integration tests with containers, synthetic monitoring per service, and versioned deployment strategies (rolling/blue-green/canary) to release independently.
📈 Typical business context: financial, government and data-platform systems where independent scalability, fault isolation and team autonomy were the drivers — combined with Hexagonal/Clean structure inside each service.
