• A.Store the photos in Amazon DynamoDB. Turn on DynamoDB Accelerator (DAX).
• B.Store the photos in an Amazon DynamoDB table. Use the DynamoDB Standard-Infrequent Access (DynamoDB Standard-IA) storage class. Store the photo metadata in Amazon ElastiCache.
• C.Store the photos in the Amazon S3 Standard storage class. Set up an S3 Lifecycle policy to move photos older than 30 days to the S3 Standard-Infrequent Access (S3 Standard-IA) storage class. Use object tags to keep track of metadata.

• A.Application Load Balancer
• B.AWS Batch
• C.Amazon EC2 Auto Scaling
• D.Amazon S3 website hosting

• A.AWS DataSync
• B.Amazon Elastic File System (Amazon EF5)
• C.Amazon EMR File System (Amazon EMRFS)
