AWS long-term archival storage service for data you rarely access. Like putting old documents in a warehouse - cheaper to store but takes time to retrieve.
A company stores old employee records in Glacier for compliance, accessing them only when legally required.
All are low-cost, long-term object storage options designed for rarely accessed data. They trade lower storage price for higher retrieval latency and/or retrieval fees, making them best for archives, compliance records, and backups kept for long retention.
