A founder once asked me to review an architecture pitch.
The agency proposed eleven services, a message queue, and a service mesh. This was for a simple booking tool with zero users.
That is a trap.
Architecture decisions set your hosting bills, your shipping speed, and your hiring plan. You must know the cost before you hand a developer a budget.
The Monolith A monolith uses one codebase, one deployment, and one database. It is simple.
On day one, you do not know your domain boundaries. If you split services too early, you spend time moving walls that should not exist. A monolith is easier to manage when your team is small. You call a function instead of setting up an API. When a bug happens at 2am, the error points to the code, not a network failure.
Microservices Microservices solve organizational problems. They allow different teams to ship code on their own schedules. Netflix uses them to prevent one fault from sinking the whole ship.
However, you pay for this every day. Network calls add latency. Data consistency becomes difficult. You need specialized tools and a large team to manage logs and tracing. Without the right headcount, you end up with a distributed monolith. This gives you all the complexity of a network with none of the independence.
The Modular Monolith This is the middle ground. It is one app with firm walls between different parts of the code. Billing cannot touch the guts of your orders.
Shopify and GitHub use this approach. You get clean boundaries and avoid the network tax. When a part of your app finally needs to scale alone, you can split it out easily because the edges are already defined.
How to decide:
- Team size: If you have three people, you cannot manage separate services and the required on-call rotation.
- Product stability: If your product changes weekly, your service boundaries will be wrong by next month.
- Operations: Do you have automated rollbacks and log aggregation? If not, microservices will cause pain.
- Scale: Do not build for hypothetical growth. Build for the concrete path you can see.
If your answers are "not yet," build a modular monolith.
Do not ask for microservices because the word sounds modern. Tell your partner what the product does and who will maintain it.
Produkte scheitern, weil sie nie veröffentlicht werden. Ein sauberer Monolith ist der schnellste Weg, um Nutzer zu erreichen. Baue das zuerst. Lass deinen Traffic entscheiden, wann es Zeit ist, die Dinge aufzuteilen.
