Microservice Architecture

How distributed systems communicate, scale, and stay resilient — from monolith decomposition to event-driven sagas and container orchestration.

Monolith

Decomposition

API Gateway

Discovery

Communication

Circuit Breaker

Saga

Event-Driven

Containers

Observability

Data Mgmt

Getting Started

When to split, strangler fig pattern, and the hidden costs of distribution.

Routing, aggregation, BFF, and gateway offloading.

DNS, Consul, client-side vs server-side LB, and health checks.

Communication Patterns

REST vs gRPC vs messaging — sync vs async trade-offs.

Polly, retry policies, bulkhead isolation, and timeout strategies.

Choreography vs orchestration for cross-service transactions.

Event bus, eventual consistency, outbox pattern, and idempotency.

Infrastructure

Pods, services, deployments, scaling, and rolling updates.

Distributed tracing, correlation IDs, and Grafana/Prometheus.

Database-per-service, data sync strategies, and CQRS for reads.
