S3 Storage Classes

AWS has many kind of S3 storage class

Amazon S3 Standard (S3 Standard)

1. Designed for high durability of 99.999999999% of objects across multiple Availability Zones.
2. If you store 10,000000 objects with Amazon S3, you can on average expect to incur a loss of a single object once every 10,000 years.
3. 99.99% Availability over a given year.
4. Sustain 2 concurrent facility failures.

Use case:
Big data analytics, mobile & gaming applications, content distribution…

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

1. Suitable for data that is less frequently accessed but requires rapid access when needed.
2. Designed for high durability of 99.999999999% of objects across multiple Availability Zones.
3. Low cost compared to Amazon s3 Standard
4. 99.99% Availability
5. Sustain 2 concurrent facility failures.

Use case:
As a data store for disaster recovery, backups…..

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

1. Same as AI but is stored in a single AZ.
2. High durability of 99.999999999% of the object in a single AZ. That means data loss when your AZ is destroyed.
3. 99.95% Availability.
4. Low latency and high throughput performance
5. Low cost compared to AI (by 20%)

Use case:
Storing secondary backup copies of on-remise data, or storing any kind of data so that we can recreate.

S3 Intelligent-Tiering

1. Low latency and high throughput performance as S3 Standard.
2. Small monthly monitoring and auto-tiering fee.
3. Automatically moves objects between two access tiers based on changing access patterns.
4. Designed for high durability of 99.999999999% of objects across multiple Availability Zones.
5. 99.99% Availability over a given year.

Amazon S3 Glacier

1. Low-cost object storage meant for archiving/ backup
2. Data is retained for the longer term(10s of year).
3. It’s a big alternative to on-premise magnetic tape storage.
4. The average annual durability is 99.999999%.
5. Cost per storage per month ($0.0041/GB) + retrieval cost.
6. Each item in Glacier is called “Archive” (up to 40TB).
7. Archives are stored in “Vaults”.

Use case:
Storing secondary backup copies of on-remise data, or storing any kind of data so that we can recreate.
