Which solution will meet these requirements MOST cost-effectively?
Store individual files with tags in Amazon S3 Glacier Instant Retrieval. Query the tags to retrieve the files from S3 Glacier Instant Retrieval.
Store individual files in Amazon S3 Intelligent-Tiering. Use S3 Lifecycle policies to move the files to S3 Glacier Flexible Retrieval after 1 year. Query and retrieve the files that are in Amazon S3 by using Amazon Athena. Query and retrieve the files that are in S3 Glacier by using S3 Glacier Select.
Store individual files with tags in Amazon S3 Standard storage. Store search metadata for each archive in Amazon S3 Standard storage. Use S3 Lifecycle policies to move the files to S3 Glacier Instant Retrieval after 1 year. Query and retrieve the files by searching for metadata from Amazon S3.
Store individual files in Amazon S3 Standard storage. Use S3 Lifecycle policies to move the files to S3 Glacier Deep Archive after 1 year. Store search metadata in Amazon RDS. Query the files from Amazon RDS. Retrieve the files from S3 Glacier Deep Archive.
Explanations:
S3 Glacier Instant Retrieval is optimized for infrequent access, making it unsuitable for files accessed frequently within the first year. Querying tags in S3 Glacier for recent files adds complexity and may lead to delays.
Storing files in S3 Intelligent-Tiering allows for quick access to recent files, while S3 Lifecycle policies efficiently transition older files to S3 Glacier Flexible Retrieval. Athena can query S3 data easily, making this a cost-effective solution.
While S3 Standard storage allows quick access to recent files, transitioning to S3 Glacier Instant Retrieval after one year may not be the most cost-effective approach for infrequent access. Querying metadata in S3 adds complexity without optimizing cost for older files.
Storing files in S3 Standard initially is good, but moving to S3 Glacier Deep Archive after one year may incur higher retrieval times and costs. Relying on RDS for metadata adds additional complexity and potential costs that are unnecessary for infrequent access.
As I recall, the answer is:
Store individual files in Amazon S3 Intelligent-Tiering. Use S3 Lifecycle policies to move the files to S3 Glacier Flexible Retrieval after 1 year. Query and retrieve the files that are in Amazon S3 by using Amazon Athena. Query and retrieve the files that are in S3 Glacier by using S3 Glacier Select.
