Monolith to Microservices#

The decision to break a monolith into microservices is one of the most consequential architectural choices a team makes. Get it right and you unlock independent deployment, team autonomy, and targeted scaling. Get it wrong and you trade a manageable monolith for a distributed monolith – all the complexity of microservices with none of the benefits.

When to Stay with a Monolith#

Microservices are not an upgrade from monoliths. They are a different set of tradeoffs. A well-structured monolith is the right choice in many situations.
