Occam's Razor

Occam’s Razor is a problem-solving principle that reminds us that when we have multiple possible solutions, the simplest one is preferred.

In software, this principle supports the KISS (“Keep It Simple, Stupid”) approach. When we decide to keep our implementations simple, we reduce the risk of further complications.

For example, if a software architecture can achieve its goals with a monolith and one database, there is no need to split it into five microservices and two databases. These extra components would only introduce complexity and potential integration and coordination issues, but no benefits.

This is a reminder to avoid the temptation of over-engineering and keep things simple.

• Simple code is easier to understand, maintain, and debug, whereas complex code has more potential points of failure. Remove or avoid unnecessary moving parts in system architecture.
• When debugging, start with the simplest explanation before jumping into complex theories.
• Adding more features to the app can only complicate a product without adding real value. Occam's Razor reminds us that less is more in many cases.
