A company stores call transcript files monthly. Users access files randomly within 1 year of the call, but access becomes infrequent after 1 year. The company wants users to be able to query and retrieve files less than 1 year old as quickly as possible; delays for older files are acceptable. Which solution meets these requirements most cost-effectively?

S3 Intelligent-Tiering automatically moves objects between access tiers based on access patterns, optimizing costs without performance impact for frequently accessed data. After 1 year, when access becomes infrequent, S3 Lifecycle policies can transition files to S3 Glacier Flexible Retrieval, which is more cost-effective for archival data where retrieval delays are acceptable. Amazon Athena can query data directly in S3, and S3 Glacier Select allows querying data within Glacier without full retrieval, providing cost-effective access for both active and archived data. Storing files directly in S3 Glacier Instant Retrieval is not optimal for frequently accessed data due to higher access costs compared to S3 Standard or Intelligent-Tiering. Using S3 Standard for 1 year before moving to Glacier Instant Retrieval is less cost-effective than Intelligent-
