When should I use microservices?

When you have multiple teams, need independent scaling for different features, or are building a platform with distinct domains. For most startups and MVPs, a monolith is the better starting point.

How do microservices communicate?

Synchronously via REST or gRPC for request-response patterns. Asynchronously via message queues (RabbitMQ, Kafka) for event-driven communication. Most systems use a mix of both.

Microservices Architecture Explained

Independent services, independent deployments, independent scaling — the architecture pattern for complex, evolving systems.

Microservices Architecture

An architectural pattern where an application is built as a collection of loosely coupled, independently deployable services, each responsible for a specific business capability.

Explanation

In a microservices architecture, instead of one large application (monolith), you have many small services that communicate via APIs or message queues. Each service has its own database, deployment pipeline, and team. Benefits include independent scaling, technology flexibility, and fault isolation. Drawbacks include increased operational complexity, network latency, and the need for distributed system patterns (circuit breakers, sagas, service discovery). Microservices make sense when teams need to scale independently and the domain is complex enough to justify the overhead.

Bookuvai Implementation

Bookuvai builds microservices when the project requires independent scaling or multiple teams. Our standard approach uses Node.js services with REST or GraphQL APIs, MongoDB or PostgreSQL per service, and Docker/Kubernetes for orchestration. For simpler projects, we recommend starting with a modular monolith and splitting into microservices only when needed.
