Use cases

Media asset workflows

Media and entertainment assets such as video and news footage require durable storage and can grow to many petabytes over time. Much of this data needs to be available immediately for breaking news events, video rendering, or content development. The Amazon S3 Glacier Instant Retrieval storage class allows you to archive older media content affordably while still making it available in milliseconds when it’s needed. To save even more on storage costs for media archives that don’t require milliseconds access, you can use S3 Glacier or S3 Glacier Deep Archive.

Healthcare information archiving

Hospital systems need to retain petabytes of patient records (such as LIS, PACS, and EHR) for decades to meet regulatory requirements. The Amazon S3 Glacier and S3 Glacier Deep Archive storage classes help you reliably archive patient record data securely at a very low cost. The Amazon S3 Glacier Instant Retrieval storage class is ideal for medical images or genomics, where milliseconds retrieval is required.

Regulatory, compliance, and business policy archiving

Many enterprises like financial services and healthcare must retain regulatory and compliance archives for extended durations. Company policies can also require record retention of several years or indefinitely for data such as finance, tax, HR, or email records that can use S3 Glacier storage classes for a long-term content archive.

Scientific data storage

Research organizations generate, analyze, and archive vast amounts of data, such as for genomics or to train machine learning models. With the Amazon S3 Glacier Instant Retrieval storage class, you avoid the complexities of hardware and facility management and capacity planning, with the low-cost storage and milliseconds retrieval.

Digital preservation

Libraries and government agencies face data integrity challenges in their digital preservation efforts. Unlike traditional systems, which can require laborious data verification and manual repair, Amazon S3 performs regular, systematic data integrity checks and is built to be automatically self-healing. Using S3 Lifecyle, you can transition data to lower-cost storage classes to optimize your savings.

Long-term backup retention

As part of backup plans, businesses store large data backups for many years on expensive on-premises storage systems. The S3 Glacier storage classes deliver very low-cost archive storage for these backups, while also making the data available when needed.

Tape replacement

On-premises or offsite tape libraries can lower storage costs but require large upfront investments and specialized maintenance. The Amazon S3 Glacier storage classes have no upfront costs and eliminate the cost and burden of maintenance, while providing faster access than on-premises tape archives.
