Amazon S3 storage classes

There are six S3 storage classes. 

  1. Amazon S3 Standard: This is considered general purpose storage for cloud applications, dynamic websites, content distribution, mobile and gaming applications, and big data analytics.
  2. Amazon S3 Intelligent-Tiering: This tier is useful if your data has unknown or changing access patterns. S3 Intelligent-Tiering stores objects in two tiers, a frequent access tier and an infrequent access tier. Amazon S3 monitors access patterns of your data, and automatically moves your data to the most cost-effective storage tier based on frequency of access.
  3. 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 storage tier is ideal if you want to store long-term backups, disaster recovery files, and so on.
  4. Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA): 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.
  5. Amazon 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.
  6. Amazon S3 Glacier Deep Archive: S3 Glacier Deep Archive is Amazon S3’s lowest-cost storage class and supports long-term retention and digital preservation for data that may be accessed once or twice in a year. It is designed for customers—particularly those in highly regulated industries, such as the Financial Services, Healthcare, and Public Sectors—that retain data sets for 7 to 10 years or longer to meet regulatory compliance requirements.
