Anti-Patterns
Common architectural mistakes that teams repeatedly fall into — recognize them early, understand why they happen, and know how to escape.
Big Ball of Mud
Haphazardly structured systems with no recognizable architecture — and how they form.
Distributed Monolith
Microservices that retained the tight coupling of a monolith — the worst of both worlds.
God Object / God Service
A class or service that knows too much and does too much.
Chatty I/O
Excessive fine-grained network calls that kill performance — and how to batch them.
Premature Optimization
Optimizing before measuring — sacrificing clarity for gains that may never matter.
Vendor Lock-In
Tight coupling to proprietary APIs that prevents switching providers.
Golden Hammer
Applying a familiar technology to every problem regardless of fit.
Magic Pushbutton
UIs and APIs that trigger complex, opaque operations with no feedback or control.
Resume-Driven Development
Choosing technologies for their CV appeal rather than their fitness for the problem.
Chatty Services
Microservices that make excessive synchronous calls to each other.
God Service
A microservice that has grown to own too many responsibilities.
Leaky Abstractions
Abstractions that expose implementation details they were meant to hide.
Shared Database
Multiple services directly accessing the same database, creating hidden coupling.
Tight Coupling
Dependencies so strong that changing one component requires changing another.
