Architecture

Software design patterns, system design, and architectural decision-making.

Architecture is about making the right trade-offs. This section covers patterns, principles, and real-world case studies to help you design resilient, scalable systems.

Core Patterns

Separation of Concerns

Divide your system into distinct sections, each addressing a separate concern.

foundational

Layered Architecture

Presentation, business logic, and data access in isolated layers.

monolith · enterprise

Microservices

Independent services communicating over well-defined APIs.

distributed · cloud

Event-Driven Architecture

Services communicate through events — loose coupling, async processing.

async · scalable

Case Studies

Seamonkeys Case Study

A non-proprietary case study to evaluate architectural concepts and framework decisions.

Decision Framework

When choosing an architecture, consider:

Factor Monolith Microservices Event-Driven
Team size Small Multiple teams Multiple teams
Deploy frequency Low–Medium High High
Complexity Low High High
Latency Low Network-dependent Async
Data consistency Easy Hard (distributed tx) Eventual
Scaling Vertical Horizontal per service Horizontal per handler

Start simple. Extract services only when you have a clear reason — team boundaries, independent scaling, or deploy cadence.

Event-Driven Architecture

Services communicate through events for loose coupling and async processing.

Layered Architecture

Organize your application into presentation, business logic, and data access layers.

Microservices

Independent services communicating over well-defined APIs.
