Learning Path Overview

Software Architecture & Design Patterns

Learn to design software systems with intentional structure — from design patterns to architectural styles and real-world trade-offs.

Software architecture is the set of decisions that are hardest to reverse. This path teaches learners to think architecturally — understanding quality attributes, evaluating trade-offs, applying the right design patterns for the right problems, and choosing architectural styles that serve long-term product goals. By the end, learners will be equipped not just to follow existing architectures but to reason about, communicate, and evolve them with confidence.

Introduction

What this path is about

Software architecture is the set of decisions that are hardest to reverse. This path teaches learners to think architecturally — understanding quality attributes, evaluating trade-offs, applying the right design patterns for the right problems, and choosing architectural styles that serve long-term product goals. By the end, learners will be equipped not just to follow existing architectures but to reason about, communicate, and evolve them with confidence.

Goals

What you should be able to do

  • Think in terms of system structure, quality attributes, and architectural trade-offs rather than just features.
  • Apply design patterns from the Gang of Four and beyond to solve recurring structural problems.
  • Understand architectural styles and when each is appropriate for specific product and team contexts.
  • Communicate architectural decisions clearly through documentation, diagrams, and structured decision records.

Path Structure

What is inside the Software Architecture & Design Patterns path

The path is split into practical stages. Each stage prepares you for the next one, so you do not just memorize concepts, you build real delivery readiness.

01Stage One

Architecture Thinking

Develop the mental models for reasoning about software structure, quality, and long-term system health.

  • What architecture is and why it matters: structure, behavior, and cross-cutting concerns
  • Quality attributes: performance, scalability, maintainability, security, and testability
  • Architectural trade-offs: understanding that every decision creates cost somewhere
  • Reading and reasoning about existing architectures before designing new ones
02Stage Two

Design Patterns

Learn the canonical design patterns, understand the problems they solve, and recognize when not to use them.

  • Creational patterns: Factory, Abstract Factory, Builder, Singleton, and Prototype
  • Structural patterns: Adapter, Decorator, Facade, Composite, and Proxy
  • Behavioral patterns: Strategy, Observer, Command, Chain of Responsibility, and State
  • Anti-patterns and over-engineering: recognizing when patterns add complexity without value
03Stage Three

Architectural Styles and Patterns

Understand the major architectural styles and the contexts in which each delivers the most value.

  • Layered architecture and the separation of concerns across application tiers
  • Hexagonal and clean architecture: protecting domain logic from infrastructure
  • Event-driven architecture: events, commands, messaging patterns, and eventual consistency
  • Microservices: decomposition strategies, service boundaries, and the hidden costs of distribution
04Stage Four

Architecture in Practice

Apply architectural thinking to real systems through documentation, evaluation, and evolutionary design.

  • Architecture decision records: capturing context, options, and rationale for future teams
  • C4 diagrams and structured visual communication of system design
  • Evaluating existing architectures: identifying pain points and prioritizing improvement
  • Evolutionary architecture: designing for change without over-engineering for the future
