Quiz and Summary
Explore AWS storage and database architectures to understand how to choose the right service based on access patterns, latency, and cost. Learn about core storage paradigms, relational and NoSQL databases, specialized solutions, and hybrid architectures. Test your knowledge through scenario-based questions to strengthen your architectural decision-making skills.
This chapter examined the full spectrum of AWS storage and database services, establishing how access patterns, latency requirements, concurrency needs, durability expectations, and cost constraints drive architectural decisions across object, block, file, relational, NoSQL, specialized, and hybrid storage layers.
Storage architecture design
AWS storage architecture is built around three core paradigms: object storage with Amazon S3, block storage with Amazon EBS, and shared file storage with Amazon EFS and FSx. Each model addresses different workload requirements around durability, latency, scalability, and sharing semantics. Performance optimization depends on selecting the correct storage tier and validating infrastructure limits such as EBS bandwidth ceilings, EFS throughput modes, and AZ placement to balance ...
