Caching — Google Cloud Professional Cloud Architect Practice Questions
Caching reduces latency and backend load by temporarily storing frequently accessed data closer to the consumer, and it is a critical design pattern tested on the Professional Cloud Architect exam. Google Cloud supports caching at multiple layers, including Cloud CDN for static and dynamic web content, Memorystore for application-level in-memory caching, and Cloud Armor with caching policies. Architects must identify which layer of the stack benefits from caching, choose the appropriate service, and understand cache invalidation strategies that affect data consistency.
