  Amazon S3 offers a range of storage classes that you can choose from based on the performance, data access, resiliency, and cost requirements of your workloads. S3 storage classes are purpose-built to provide the lowest cost storage for different access patterns. S3 storage classes are ideal for virtually any use case, including those with demanding performance needs, data lakes, residency requirements, unknown or changing access patterns, or archival storage. \n

  The S3 storage classes include S3 Intelligent-Tiering for automatic cost savings for data with unknown or changing access patterns, S3 Standard for frequently accessed data, S3 Express One Zone for your most frequently accessed data, S3 Standard-Infrequent Access (S3 Standard-IA) and S3 One Zone-Infrequent Access (S3 One Zone-IA) for less frequently accessed data, S3 Glacier Instant Retrieval for archive data that needs immediate access, S3 Glacier Flexible Retrieval (formerly S3 Glacier) for rarely accessed long-term data that does not require immediate access, and Amazon S3 Glacier Deep Archive (S3 Glacier Deep Archive) for long-term archive and digital preservation with retrieval in hours at the lowest cost storage in the cloud. \n

  Amazon S3 provides the most durable storage in the cloud. Based on its unique architecture, S3 is designed to exceed 99.999999999% (11 nines) data durability. Additionally, S3 stores data redundantly across a minimum of 3 Availability Zones by default, providing built-in resilience against widespread disaster. Customers can store data in a single AZ to minimize storage cost or latency, in multiple AZs for resilience against the permanent loss of an entire data center, or in multiple AWS Regions to meet geographic resilience requirements. If you have data residency requirements that can’t be met by an existing AWS Region, you can use the S3 Outposts storage class to store your S3 data on premises. \n

  You can configure S3 storage classes at the object level, and a single general purpose bucket can contain objects stored across all storage classes except S3 Express One Zone. Amazon S3 also offers capabilities to manage your data throughout its lifecycle. Once an S3 Lifecycle policy is set, your data will automatically transfer to a different storage class without any changes to your application. S3 directory buckets only allow objects stored in the S3 Express One Zone storage class, which provides faster data processing within a single Availability Zone, and do not support S3 Lifecycle policies. \n

  Amazon S3 Intelligent-Tiering (S3 Intelligent-Tiering) is the first cloud storage that automatically reduces your storage costs on a granular object level by automatically moving data to the most cost-effective access tier based on access frequency, without performance impact, retrieval fees, or operational overhead. S3 Intelligent-Tiering delivers milliseconds latency and high throughput performance for frequently, infrequently, and rarely accessed data in the Frequent, Infrequent, and Archive Instant Access tiers. You can use S3 Intelligent-Tiering as the default storage class for virtually any workload, especially data lakes, data analytics, new applications, and user-generated content. \n

  For a small monthly object monitoring and automation charge, S3 Intelligent-Tiering monitors access patterns and automatically moves objects that have not been accessed to lower-cost access tiers. S3 Intelligent-Tiering automatically stores objects in three access tiers: one tier that is optimized for frequent access, a 40% lower-cost tier that is optimized for infrequent access, and a 68% lower-cost tier optimized for rarely accessed data. S3 Intelligent-Tiering monitors access patterns and moves objects that have not been accessed for 30 consecutive days to the Infrequent Access tier and after 90 days of no access to the Archive Instant Access tier. For data that does not require immediate retrieval, you can set up S3 Intelligent-Tiering to monitor and automatically move objects that aren’t accessed for 180 days or more to the Deep Archive Access tier to realize up to 95% in storage cost savings. \n

  There are no retrieval charges in S3 Intelligent-Tiering. If an object in the Infrequent or Archive Instant Access tier is accessed later, it’s automatically moved back to the Frequent Access tier. If the object you’re retrieving is stored in the optional Deep Archive tiers, before you can retrieve the object, you must first restore a copy using RestoreObject.  For information about restoring archived objects, see Restoring Archived Objects. No additional tiering charges apply when objects are moved between access tiers within the S3 Intelligent-Tiering storage class. \n

  Key features: \n

  \n
  • Automatic cost savings for data with unknown or changing access patterns \n
  • Frequent, Infrequent, and Archive Instant Access tiers have the same low-latency and high-throughput performance of S3 Standard \n
  • The Infrequent Access tier saves up to 40% on storage costs \n

                  Amazon S3 offers a range of storage classes that you can choose from based on the performance, data access, resiliency, and cost requirements of your workloads. S3 storage classes are purpose-built to provide the lowest cost storage for different access patterns. S3 storage classes are ideal for virtually any use case, including those with demanding performance needs, data lakes, residency requirements, unknown or changing access patterns, or archival storage.

                  The S3 storage classes include S3 Intelligent-Tiering for automatic cost savings for data with unknown or changing access patterns, S3 Standard for frequently accessed data, S3 Express One Zone for your most frequently accessed data, S3 Standard-Infrequent Access (S3 Standard-IA) and S3 One Zone-Infrequent Access (S3 One Zone-IA) for less frequently accessed data, S3 Glacier Instant Retrieval for archive data that needs immediate access, S3 Glacier Flexible Retrieval (formerly S3 Glacier) for rarely accessed long-term data that does not require immediate access, and Amazon S3 Glacier Deep Archive (S3 Glacier Deep Archive) for long-term archive and digital preservation with retrieval in hours at the lowest cost storage in the cloud.

                  Amazon S3 provides the most durable storage in the cloud. Based on its unique architecture, S3 is designed to exceed 99.999999999% (11 nines) data durability. Additionally, S3 stores data redundantly across a minimum of 3 Availability Zones by default, providing built-in resilience against widespread disaster. Customers can store data in a single AZ to minimize storage cost or latency, in multiple AZs for resilience against the permanent loss of an entire data center, or in multiple AWS Regions to meet geographic resilience requirements. If you have data residency requirements that can’t be met by an existing AWS Region, you can use the S3 Outposts storage class to store your S3 data on premises.

                  You can configure S3 storage classes at the object level, and a single general purpose bucket can contain objects stored across all storage classes except S3 Express One Zone. Amazon S3 also offers capabilities to manage your data throughout its lifecycle. Once an S3 Lifecycle policy is set, your data will automatically transfer to a different storage class without any changes to your application. S3 directory buckets only allow objects stored in the S3 Express One Zone storage class, which provides faster data processing within a single Availability Zone, and do not support S3 Lifecycle policies.

                  Amazon S3 Intelligent-Tiering (S3 Intelligent-Tiering)

                  Amazon S3 Intelligent-Tiering (S3 Intelligent-Tiering) is the first cloud storage that automatically reduces your storage costs on a granular object level by automatically moving data to the most cost-effective access tier based on access frequency, without performance impact, retrieval fees, or operational overhead. S3 Intelligent-Tiering delivers milliseconds latency and high throughput performance for frequently, infrequently, and rarely accessed data in the Frequent, Infrequent, and Archive Instant Access tiers. You can use S3 Intelligent-Tiering as the default storage class for virtually any workload, especially data lakes, data analytics, new applications, and user-generated content.

                  For a small monthly object monitoring and automation charge, S3 Intelligent-Tiering monitors access patterns and automatically moves objects that have not been accessed to lower-cost access tiers. S3 Intelligent-Tiering automatically stores objects in three access tiers: one tier that is optimized for frequent access, a 40% lower-cost tier that is optimized for infrequent access, and a 68% lower-cost tier optimized for rarely accessed data. S3 Intelligent-Tiering monitors access patterns and moves objects that have not been accessed for 30 consecutive days to the Infrequent Access tier and after 90 days of no access to the Archive Instant Access tier. For data that does not require immediate retrieval, you can set up S3 Intelligent-Tiering to monitor and automatically move objects that aren’t accessed for 180 days or more to the Deep Archive Access tier to realize up to 95% in storage cost savings.

                  There are no retrieval charges in S3 Intelligent-Tiering. If an object in the Infrequent or Archive Instant Access tier is accessed later, it’s automatically moved back to the Frequent Access tier. If the object you’re retrieving is stored in the optional Deep Archive tiers, before you can retrieve the object, you must first restore a copy using RestoreObject.  For information about restoring archived objects, see Restoring Archived Objects. No additional tiering charges apply when objects are moved between access tiers within the S3 Intelligent-Tiering storage class.

                  Key features:

                  • Automatic cost savings for data with unknown or changing access patterns
                  • Frequent, Infrequent, and Archive Instant Access tiers have the same low-latency and high-throughput performance of S3 Standard
                  • The Infrequent Access tier saves up to 40% on storage costs
                  • The Archive Instant Access tier saves up to 68% on storage costs
                  • Opt-in asynchronous archive capabilities for objects that become rarely accessed
                  • Deep Archive Access tier has the same performance as Glacier Deep Archive and saves up to 95% for rarely accessed objects
                  • Designed to deliver 99.9% availability with an availability SLA of 99%
                  • Small monthly monitoring and automation charge
                  • No operational overhead, no lifecycle charges, no retrieval charges, and no minimum storage duration
                  • Objects smaller than 128KB can be stored in S3 Intelligent-Tiering but will always be charged at the Frequent Access tier rates, and are not charged the monitoring and automation charge.
