§What’s in the name?

Lagom is a Swedish word meaning “just the right amount”.

Often, when people talk about microservices, they focus on the micro part of the name, assuming it means that a service should be small. We want to emphasize that the important thing when splitting a system into services is to find the right boundaries between services. This means aligning them with bounded contexts, business capabilities, and isolation requirements. A system of right-sized microservices will naturally achieve scalability and resilience requirements and be easy to deploy and manage. So, rather than focus on how small your services should be, design “Lagom” size services.
