An application sends images to S3. The metadata for these images needs to be saved in persistent storage and is required to be indexed. Which one of the following is the best for the underlying metadata storage?
A. Amazon Aurora
B. Amazon S3
C. Amazon DynamoDB
D. Amazon RDS
Explanation:
Correct Answer – C
The most efficient storage mechanism for just storing metadata is Amazon DynamoDB. Amazon DynamoDB is normally used in conjunction with the Simple Storage service. So, after storing the images in S3, you can store their metadata in DynamoDB. You can also create secondary indexes for DynamoDB Tables.
