Task Statement 1: Design cost-optimized storage solutions.

Knowledge of:

  • Access options (for example, an S3 bucket with Requester Pays object storage)
  • AWS cost management service features (for example, cost allocation tags, multi-account billing)
  • AWS cost management tools with appropriate use cases (for example, AWS Cost Explorer, AWS Budgets, AWS Cost and Usage Report)
  • AWS storage services with appropriate use cases (for example, Amazon FSx, Amazon EFS, Amazon S3, Amazon EBS)

  • Data lifecycles
  • Hybrid storage options (for example, DataSync, Transfer Family, Storage Gateway)
  • Storage access patterns
  • Storage tiering (for example, cold tiering for object storage)
  • Storage types with associated characteristics (for example, object, file, block)

  • Designing appropriate storage strategies (for example, batch uploads to Amazon S3 compared with individual uploads)
  • Determining the correct storage size for a workload
  • Determining the lowest cost method of transferring data for a workload to AWS storage
  • Determining when storage auto scaling is required
