Стройте следующую главу, а не каждую возможность.

Every new product faces the same temptation: design the system for every future you can imagine. Multiple regions, millions of users, a dozen integrations. It feels responsible. In practice, it usually slows the product down before it has had a chance to learn anything.

Right-sized, not undersized

The alternative is not to ignore the future. It is to be precise about which parts of it matter now. A clear domain model, sensible module boundaries and a well-defined API cost little up front and keep options open. Distributed infrastructure, premature microservices and speculative abstractions cost a lot — and often solve problems you will never have.

Questions worth asking

• What is the next meaningful milestone for this product?
• Which decisions would be expensive to reverse later?
• Where can we stay simple and still change course easily?

Answering these honestly lets you invest where it counts: data integrity, security and the core flows your users depend on. Everything else can grow when the product does.

Good architecture is not the one that anticipates everything. It is the one that makes the next chapter easy to write.
