4.2. Key Architectural Concepts Review

💡 First Principle: Synthesizing and interrelating core architectural concepts and their underlying first principles provides a holistic mental model, enabling agile problem-solving and robust design decisions.

Scenario: You need to rapidly recall key distinctions between services or architectural patterns to quickly analyze a complex exam question.

This section provides a condensed review of the most critical architectural concepts and their AWS service mappings. It's designed to consolidate your understanding and highlight the relationships between different pillars and design patterns. This comprehensive recall is essential for the multi-faceted questions on the SAP-C02 exam.

⚠️ Common Pitfall: Studying services in isolation. The professional level exam requires you to understand how services work together to form a complete solution.

Key Trade-Offs:

• Specialized Services vs. General-Purpose Services: Understanding when to use a purpose-built service (like "Neptune" for a graph problem) versus a general-purpose one (like "RDS") is a key architectural skill.

Reflection Question: How does having a "holistic mental model" of interconnected AWS services and architectural patterns, rather than isolated facts, empower you to solve complex, multi-domain architectural problems efficiently and effectively on the "SAP-C02" exam?
