Monolith

The Monolithic Ball of Mud

• The Ball Of Mud represents the worst case scenario for a Monolith. Also called as Spaghetti Code.
• No clear isolation in the application.
• Complex dependencies where everything depends on every other thing.
• Hard to understand and harder to modify.

Cleaning Up The Ball Of Mud

• To clean up the ball of mud we introduce isolation into the application by dividing the application along clear domain boundaries.
• We introduce packages and libraries that help isolate related pieces of code. They provide a clean and consistent interface.
