S3 One Zone-Infrequent Access (S3 One Zone-IA; Z-IA) is a new storage class designed for customers who want a lower-cost option for infrequently accessed data, but do not require the multiple Availability Zone data resilience model of the S3 Standard and S3 Standard-Infrequent Access (S3 Standard-IA; S-IA) storage classes. S3 One Zone-IA is intended for use cases with infrequently accessed data that is re-creatable, such as storing secondary backup copies of on-premises data or for storage that is already replicated in another AWS Region for compliance or disaster recovery purposes. With S3 One Zone-IA, customers can now store infrequently accessed data within a single Availability Zone at 20% lower cost than S3 Standard-IA. In addition, S3 One Zone-IA can offer customers higher availability and durability than self-managed physical data centers, with the added benefit of having to pay only for what they use.
