AWS does support the ability for user controlled movement of data between regions for business continuance (BC), high availability (HA) and disaster recovery (DR).
Amazon S3 Glacier offers low-cost storage for infrequently accessed data with simple AWS integration, high scalability, and data replication across regions. It ensures secure, compliant storage but has slow data retrieval and complex pricing. Enhancements are needed in GDPR compliance, technical support, and integration capabilities for better user experience and billing. Despite its potential, improvements in these areas are essential for maximizing its effectiveness and affordability.
