Aws Storage Cost Optimization — AWS Solutions Architect Associate Practice Questions
AWS storage cost optimization is a major focus of the AWS Solutions Architect Associate exam, covering how to reduce spending on services like S3, EBS, EFS, and S3 Glacier without sacrificing the required availability or performance. Strategies include choosing the correct S3 storage class, applying lifecycle policies, using S3 Intelligent-Tiering for unpredictable workloads, right-sizing EBS volumes, and deleting unattached or unused resources. The exam also tests awareness of data transfer costs, such as charges for moving data out of AWS or between Availability Zones, which affect architectural decisions. Demonstrating that you can meet cost objectives while preserving durability, availability, and recovery time objectives is central to the exam's cost optimization pillar.
