Prepare for the SAP-C03 exam (AWS Certified Solutions Architect – Professional). In this lesson: choosing databases by access pattern, high availability with Multi-AZ, read replicas, Aurora Global Database, and DynamoDB global tables, block, file, and object storage with EBS, EFS, FSx, and S3, and caching strategies with ElastiCache. Includes three original practice questions.
Preview the topics
- The payment ledger runs on Aurora PostgreSQL in one Region; the bank needs a copy in a second Region with about a second of possible data loss and a managed failover. What should the architect use?
- The risk team runs thousands of compute nodes on the same market datasets in S3, and the simulations need sub-millisecond file access and very high throughput. What should the architect use?
- During the evening peak, the mobile app reads the same rate items from DynamoDB millions of times, and the team wants microsecond reads without rewriting the data access code. What should the architect add?
