Modular Monolith

One deployable unit with real, enforced internal boundaries: what makes a monolith modular rather than merely large, how modules own their data, and how to keep extraction cheap without paying for distribution.

ما ستصبح قادرًا عليه

  • Distinguish a modular monolith from both a big ball of mud and a set of microservices.
  • Define a module contract and enforce it mechanically rather than by convention.
  • Give a module ownership of its data inside a single database.
  • Use in-process events to decouple modules without introducing a network.
  • Prepare a module for extraction and judge when extraction is actually warranted.

  1. 01What Makes a Monolith Modular

    One deployable, several modules, and boundaries that something in the build actually refuses to let you cross. Without the third part it is just a large application.

  2. 02Data Ownership Inside One Database

    The hard half of modularity. One database can still give each module exclusive ownership of its tables — and doing so is what decides whether extraction is ever possible.

  3. 03Keeping Extraction Cheap Without Paying For It Now

    A modular monolith should make extracting a module a decision you can take later at moderate cost — without adopting distributed-system costs today for a service you may never need.
