The Myth of Instant Microservices
Decomposing an early-stage product into microservices too soon introduces network latency, distributed transaction complexity, and deployment overhead. Starting with a clean modular monolith is often superior.
Modular Monoliths: The Clean Middle Ground
A modular monolith enforces strict domain boundaries inside a single codebase. Modules communicate via internal interfaces without distributed network overhead, enabling easy extraction into microservices later when team scale requires it.
Event-Driven Communication with Message Brokers
When microservices are necessary, asynchronous communication via message brokers (RabbitMQ, Apache Kafka) decouples services and prevents cascading network failures across system boundaries.
Distributed Tracing and Observability
Managing microservices requires centralized logging, correlation IDs, and distributed tracing metrics to pinpoint latency bottlenecks across inter-service calls.
