Building Scalable Digital Products
Scale is usually a modelling problem long before it is an infrastructure problem.

Teams tend to think about scale as traffic. In practice, the first thing that breaks is the data model. A schema that reflected the prototype rather than the business starts requiring special cases, and every new feature adds two more.
Getting this right early is cheap. Naming the entities correctly, deciding what is a first-class record and keeping derived values derived costs a few days at the start and saves months later.
The second lever is boundaries. Typed interfaces between modules mean a change stays local. Without them, every change is a whole-system change and delivery slows down permanently.
Infrastructure matters, but it is the easier problem. Caching, rendering strategy and database indexes are solvable once the model underneath is sound.
