Microservices vs Modular Monolith: Choosing the Right Software Architecture

Choosing the right software architecture early in a project prevents premature optimization and high operational overhead.

1. The Modular Monolith Advantage

For early-stage startups, a modular monolith provides fast development velocity, simple single-database transactions, and straightforward deployments while maintaining clean domain boundaries inside the codebase.

2. Transitioning to Microservices

Microservices make sense when independent teams need to deploy separate domain services autonomously or when specific components require dedicated compute scaling (e.g. video processing or AI inference).
