An organization is storing large files in Amazon S3, and is writing a web application to display meta-data about the files to end-users.Based on the metadata a user selects an object to download.The organization needs a mechanism to index the files and provide single-digit millisecond latency retrieval for the metadata.
What AWS service should be used to accomplish this?
Amazon DynamoDB
Amazon EC2
AWS Lambda
Amazon RDS
Explanations:
Amazon DynamoDB provides single-digit millisecond latency retrieval, making it suitable for fast metadata access.
Amazon EC2 provides compute resources but does not inherently offer an indexing or storage solution for metadata.
AWS Lambda can be used for processing but is not suitable for storing and retrieving metadata with low-latency access.
Amazon RDS is a relational database that may not offer the same low-latency retrieval as DynamoDB for large-scale data.
To the best of my knowledge, the answer is:
Amazon DynamoDB
