Feature Amazon S3 Metadata Azure Blob Storage Google Cloud Storage
Flexibility Allows both system-defined and user-defined metadata tags, offering full customization for data management. Limited flexibility; stricter metadata structure and size limitations. Custom metadata supported but lacks the flexibility of Amazon S3 Metadata.
Query Options Advanced querying through Athena and S3 Select enables direct metadata queries without external tools. No equivalent advanced querying tools; requires additional configurations. Limited native querying capabilities; metadata often requires external integrations.
Ecosystem Integration Seamlessly integrates with AWS tools like Glue, QuickSight, and Lambda for analytics, automation, and security. Limited integration across Azure services, focusing primarily on storage functions. Basic integration with Google services; lacks advanced cross-service workflows.
