Deciding on your backend application structure is one of the most consequential decisions a CTO will make. Here, we compare the cost, speed, and deployment trade-offs between monoliths and microservices.
1. When to Choose a Modular Monolith
For 90% of projects starting out, a modular monolith built with a clean, separated folder structure is superior. It reduces deployment complexity, avoids network latency, and enables rapid iteration before product-market fit.
2. Transitioning to Microservices
When your development team exceeds 50 engineers or specific features require dedicated CPU scaling (like video rendering or heavy calculations), splitting them into isolated microservices on ECS or Kubernetes becomes essential.
3. Hybrid Edge Orchestration
Leverage next-generation systems like Next.js Serverless and edge routes. You get the simplicity of a single monorepo repository while Next.js automatically splits code boundaries at compile-time.
- Monoliths minimize early stage infrastructure budgets
- Microservices prevent deploy conflicts across large teams
- Enforce strict API boundaries between modules
