Amazon S3 offers a range of storage classes designed for different use cases. These include S3 Standard for general-purpose storage of frequently accessed data; S3 Intelligent-Tiering for data with unknown or changing access patterns; S3 Standard-Infrequent Access (S3 Standard-IA) and S3 One Zone-Infrequent Access (S3 One Zone-IA) for long-lived, but less frequently accessed data; and Amazon S3 Glacier (S3 Glacier) and Amazon S3 Glacier Deep Archive (S3 Glacier Deep Archive) for long-term archive and digital preservation. 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.  

General purpose

Amazon S3 Standard (S3 Standard)

S3 Standard offers high durability, availability, and performance object storage for frequently accessed data. Because it delivers low latency and high throughput, S3 Standard is appropriate for a wide variety of use cases, including cloud applications, dynamic websites, content distribution, mobile and gaming applications, and big data analytics. S3 Storage Classes can be configured at the object level and a single bucket can contain objects stored across S3 Standard, S3 Intelligent-Tiering, S3 Standard-IA, and S3 One Zone-IA. You can also use S3 Lifecycle policies to automatically transition objects between storage classes without any application changes.

Key Features:

  • Low latency and high throughput performance
  • Designed for durability of 99.999999999% of objects across multiple Availability Zones
  • Resilient against events that impact an entire Availability Zone
  • Designed for 99.99% availability over a given year
  • Backed with the Amazon S3 Service Level Agreement for availability
  • Supports SSL for data in transit and encryption of data at rest
  • S3 Lifecycle management for automatic migration of objects to other S3 Storage Classes  

Unknown or changing access

Amazon S3 Intelligent-Tiering (S3 Intelligent-Tiering) — NEW

The S3 Intelligent-Tiering storage class is designed to optimize costs by automatically moving data to the most cost-effective access tier, without performance impact or operational overhead. It works by storing objects in two access tiers: one tier that is optimized for frequent access and another lower-cost tier that is optimized for infrequent access. For a small monthly monitoring and automation fee per object, Amazon S3 monitors access patterns of the objects in S3 Intelligent-Tiering, and moves the ones that have not been accessed for 30 consecutive days to the infrequent access tier. If an object in the infrequent access tier is accessed, it is automatically moved back to the frequent access tier. There are no retrieval fees when using the S3 Intelligent-Tiering storage class, and no additional tiering fees when objects are moved between access tiers. It is the ideal storage class for long-lived data with access patterns that are unknown or unpredictable. S3 Storage Classes can be configured at the object level and a single bucket can contain objects stored in S3 Standard, S3 Intelligent-Tiering, S3 Standard-IA, and S3 One Zone-IA. You can upload objects directly to S3 Intelligent-Tiering, or use S3 Lifecycle policies to transfer objects from S3 Standard and S3 Standard-IA to S3 Intelligent-Tiering. You can also archive objects from S3 Intelligent-Tiering to S3 Glacier.

Key Features:

  • Same low latency and high throughput performance of S3 Standard
  • Small monthly monitoring and auto-tiering fee
  • Automatically moves objects between two access tiers based on changing access patterns
  • Designed for durability of 99.999999999% of objects across multiple Availability Zones
  • Resilient against events that impact an entire Availability Zone
  • Designed for 99.9% availability over a given year
  • Backed with the Amazon S3 Service Level Agreement for availability
  • Supports SSL for data in transit and encryption of data at rest
  • S3 Lifecycle management for automatic migration of objects to other S3 Storage Classes

Infrequent access

Amazon S3 Standard-Infrequent Access (S3 Standard-IA)

S3 Standard-IA is for data that is accessed less frequently, but requires rapid access when needed. S3 Standard-IA offers the high durability, high throughput, and low latency of S3 Standard, with a low per GB storage price and per GB retrieval fee. This combination of low cost and high performance make S3 Standard-IA ideal for long-term storage, backups, and as a data store for disaster recovery files. S3 Storage Classes can be configured at the object level and a single bucket can contain objects stored across S3 Standard, S3 Intelligent-Tiering, S3 Standard-IA, and S3 One Zone-IA. You can also use S3 Lifecycle policies to automatically transition objects between storage classes without any application changes.

Key Features:

  • Same low latency and high throughput performance of S3 Standard
  • Designed for durability of 99.999999999% of objects across multiple Availability Zones
  • Resilient against events that impact an entire Availability Zone
  • Data is resilient in the event of one entire Availability Zone destruction
  • Designed for 99.9% availability over a given year
  • Backed with the Amazon S3 Service Level Agreement for availability
  • Supports SSL for data in transit and encryption of data at rest
  • S3 Lifecycle management for automatic migration of objects to other S3 Storage Classes

Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA)

S3 One Zone-IA is for data that is accessed less frequently, but requires rapid access when needed. Unlike other S3 Storage Classes which store data in a minimum of three Availability Zones (AZs), S3 One Zone-IA stores data in a single AZ and costs 20% less than S3 Standard-IA. S3 One Zone-IA is ideal for customers who want a lower-cost option for infrequently accessed data but do not require the availability and resilience of S3 Standard or S3 Standard-IA. It’s a good choice for storing secondary backup copies of on-premises data or easily re-creatable data. You can also use it as cost-effective storage for data that is replicated from another AWS Region using S3 Cross-Region Replication.

S3 One Zone-IA offers the same high durability†, high throughput, and low latency of S3 Standard, with a low per GB storage price and per GB retrieval fee. S3 Storage Classes can be configured at the object level, and a single bucket can contain objects stored across S3 Standard, S3 Intelligent-Tiering, S3 Standard-IA, and S3 One Zone-IA. You can also use S3 Lifecycle policies to automatically transition objects between storage classes without any application changes.

Key Features:

  • Same low latency and high throughput performance of S3 Standard
  • Designed for durability of 99.999999999% of objects in a single Availability Zone†
  • Designed for 99.5% availability over a given year
  • Backed with the Amazon S3 Service Level Agreement for availability
  • Supports SSL for data in transit and encryption of data at rest
  • S3 Lifecycle management for automatic migration of objects to other S3 Storage Classes

† Because S3 One Zone-IA stores data in a single AWS Availability Zone, data stored in this storage class will be lost in the event of Availability Zone destruction.

Archive

Amazon S3 Glacier (S3 Glacier)

S3 Glacier is a secure, durable, and low-cost storage class for data archiving. You can reliably store any amount of data at costs that are competitive with or cheaper than on-premises solutions. To keep costs low yet suitable for varying needs, S3 Glacier provides three retrieval options that range from a few minutes to hours. You can upload objects directly to S3 Glacier, or use S3 Lifecycle policies to transfer data between any of the S3 Storage Classes for active data (S3 Standard, S3 Intelligent-Tiering, S3 Standard-IA, and S3 One Zone-IA) and S3 Glacier.
