The first and largest PCA exam domain is about turning fuzzy business requirements into a defensible technical architecture. You start by separating business requirements (regulatory deadlines, budgets, time-to-market, SLAs) from technical requirements (throughput, latency, durability, data residency) and then choosing Google Cloud building blocks that satisfy both.

Good architects design for change: they favour managed services, decouple components, and document trade-offs explicitly. A high-availability design that doubles cost may be wrong if the business only needs 99.9%; an exam answer is correct only when it matches the stated constraints.

This module introduces the Google Cloud Architecture Framework pillars — operational excellence, security, reliability, cost optimization and performance — as the lens you apply to every question.

NoteRead the stated requirement, not the most impressive technology. The exam rewards the cheapest design that still meets every requirement.
