When Microservices Earn Their Cost.

Microservices are a coordination strategy as much as a technical one. Their value appears when boundaries align with change, ownership, and operational needs.

Separate deployment, scaling, and failure domains are useful only if the team gains something concrete in return.

• A boundary has an owner.

• A boundary has a reason to change independently.

• A boundary has an operational story.
