Monolith vs. Microservices

This page will help you decide which architectural approach is best suited to your project.

Answer a few questions → Get a clear recommendation.

Options you can choose from:

Simple Monolith

The entire application is built and deployed as a single unit. All features share the same codebase, the same database, and run in a single process.

Modular Monolith

The code is internally divided into independent modules with strictly defined boundaries, but the application still runs as a single unit.

Microservices

The application is divided into a number of small independent services that have their own code, their own database, and communicate with each other over the network.

Decision questions

Answer honestly based on the current status of the project, not on where you would like the project to be in the future. Answer based on the next 6–12 months.

1. What is the size of the development team?

2. What stage is the project at?

3. What is the domain complexity of the system?

4. How often do you need to deploy parts of the system independently?

5. What is the team's experience with deploying and running applications?

6. What is more important in the coming months?
