Amazon S3 Standard-IA: This storage class is designed for data that is accessed less frequently but requires rapid access when needed. It offers lower storage costs compared to S3 Standard while still providing high availability and durability.

Access Patterns: Since the files are frequently accessed in the first 30 days and rarely accessed afterward, transitioning them to S3 Standard-IA after 30 days aligns with their access patterns and reduces storage costs significantly.

Lifecycle Policy: Implementing a lifecycle policy to transition the files to S3 Standard-IA ensures automatic management of the data lifecycle, moving files to a lower-cost storage class without manual intervention. Deleting the files after 4 years further optimizes costs by removing data that is no longer needed.

The lowest-overhead centralized access model is to connect the existingon-premises Active Directoryby usingAD Connectorand then manage AWS account access throughIAM Identity Center permission sets. AWS documentation explains that IAM Identity Center providesone place to assign permissions to multiple AWS accounts, and AD Connector is specifically designed to let AWS services use an existing directory without storing directory information in AWS. This approach preserves the company’s current authentication source and adds centralized authorization across the organization. Creating IAM users or scripting cross-account role assignments would add significant administrative work and weaken the identity model.

To upload photos to an S3 bucket using Amazon CloudFront with a custom domain name, the following components are required:

ACM in us-east-1 (Option A): When using CloudFront with HTTPS, the SSL/TLS certificate must be created in theus-east-1Region. AWS Certificate Manager (ACM) handles the provisioning, management, and renewal of public certificates, making this a cost-effective and low-maintenance solution.

S3 Transfer Acceleration (Option C): Transfer Acceleration allows faster uploads to S3 from CloudFront by routing traffic through AWS’s edge locations. This significantly speeds up the data upload process, especially for users that are geographically distant from the S3 bucket ' s region.

Option B (ACM in eu-west-1): CloudFront only supports certificates created in us-east-1.

Option D and E (OAC and website endpoint): These are not ideal for handling secure uploads or efficient data transfers in this case.

S3 File Gateway is the right gateway type because the on-premises workload needsNFS-based file accesswhile storing data in Amazon S3. AWS documentation states that File Gateway exposes NFS and SMB shares backed by S3 objects. For the archive requirement, the company is willing to wait days for retrieval, which aligns withS3 Glacier Deep Archive, AWS’s lowest-cost archival storage class for long-term retention. A lifecycle policy can transition the data automatically after 5 days. Volume Gateway is block-oriented, not NFS file-based, and Tape Gateway is intended for backup applications that use virtual tapes rather than standard NFS file shares. Therefore, File Gateway plus an S3 lifecycle transition to Glacier Deep Archive is the most cost-effective design.
