This post discusses Modular Design, an approach I wrote about for a LinkedIn article under All/Engineering/Software Design. It wasn’t accepted due to the contribution limit, but I believe it could still be useful to others. Plus, I get to flout the 750-character limit here, so I’m sharing it for posterity.
Domain Driven Design (DDD) enhances your system’s modularity by aligning code with core business domains. This creates modules that mirror your business, making the system more intuitive and easier to maintain. Clear boundaries between modules allow for independent evolution without affecting the whole system.
Focus on building a well-structured monolith using DDD principles before diving into microservices, which can add unnecessary complexity. Keeping communication between modules in-process maintains simplicity and efficiency, avoiding the overhead of cross-process communication that microservices often require.
As your system grows and scaling becomes necessary, splitting modules into microservices will be easier thanks to the established domain boundaries. Aligning your system with your business domains ensures it can adapt and grow as your needs change.
