Microservices vs Monolith

The monolith-vs-microservices debate often generates more heat than light. Both are valid architectural approaches; the right choice depends on team size, organisational structure, deployment maturity, and where you are in the product lifecycle.

Start With a Monolith

For new products, a well-structured monolith is almost always the better starting point. It is faster to build, easier to debug, and avoids the distributed systems complexity that microservices introduce. You can always extract services later once the domain boundaries are clear.

When Microservices Make Sense

Microservices become attractive when independent deployability is genuinely needed — when different parts of the system have different scaling requirements, different release cadences, or are owned by distinct teams that need to move without coordinating.

The Strangler Fig Migration

Rather than a big-bang rewrite, extract services incrementally using the Strangler Fig pattern: route specific functionality to a new service while leaving the monolith intact. Retire the monolith piece by piece once each extraction is stable.
