Storage Classes

S3 Standard

Default storage class.
For performance-sensitive use cases and frequently accessed data - Low latency and high throughput performance.
99.999999999% (11 9s) Durability.
99.99% availability over a given year - Objects stored across at least 3 Availability Zones.
If objects are stored successfully, AWS responds with a HTTP 200 OK status.

S3 Standard-Infrequent Access (S3 Standard-IA)

For less frequently accessed data but requires rapid access when needed.
99.999999999% (11 9s) Durability.
99.99% availability over a given year - Objects stored across at least 3 Availability Zones.

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

For less frequently accessed data but requires rapid access when needed, such as storing secondary backup copies of on-premises data or easily re-creatable data.
DOES NOT store data in a minimum of three Availability Zones (AZs) - Stores data in a single AZ.
Lower-cost option for infrequently accessed data but do not require the availability and resilience of S3 Standard or S3 Standard-IA.
99.999999999% (11 9s) Durability of objects in a single Availability Zone (data will be lost if AZ is destroyed).
99.5% availability over a given year.

S3 Glacier

Secure, durable, and low-cost storage class for data archiving.
Retrieval times range from minutes to hours
99.999999999% (11 9s) Durability.
3 Types of retrieval options:
- Expedited - 1-5 minutes.
- Standard - 3-5 hours.
- Bulk - 5-12 hours.

S3 Glacier Deep Archive

For long-term retention and digital preservation for data that is accessed very rarely.
Also used for backup and disaster recovery.
99.999999999% (11 9s) Durability.
3 Types of retrieval options:
- Standard - 12 hours.
- Bulk - Up to 48 hours.

S3 Intelligent-Tiering

Automatically optimizes storage costs for data with unknown or changing access patterns.
Stores objects in four access tiers, optimized for frequent, infrequent, archive, and deep archive access - Frequent and Infrequent Access tiers have same low latency and high throughput performance of S3 Standard. Archive access and deep Archive access tiers have same performance as Glacier and Glacier Deep Archive.
99.999999999% (11 9s) Durability.
99.9% availability over a given year.
