Microservices vs Monolith: The Real Trade-offs
Quick Comparison
| Factor | Monolith | Microservices |
|---|---|---|
| Complexity | Lower | Higher |
| Deployment | Simple | Complex |
| Scaling | Vertical | Horizontal |
| Team size | Small teams | Large teams |
| Development speed | Faster initially | Slower initially |
| Cost | Lower | Higher |
Start with a Monolith If:
- You are a startup or small team
- Your product is still evolving
- You have fewer than 10 developers
- You want to ship fast
- Budget is a concern
Consider Microservices If:
- You have 20+ developers on the project
- Different parts need independent scaling
- Teams need to deploy independently
- You are at proven product-market fit
- You have DevOps expertise
The Modular Monolith: Best of Both
Start with a well-structured monolith with clear module boundaries. When you need to, extract modules into microservices. This approach gives you monolith simplicity with future flexibility.
My Recommendation
For 95% of projects I work on, a modular monolith is the right choice. Microservices add complexity that most startups do not need.
Build a solid architecture for your project.
