S3 Object Storage Class

Nov 5, 2022

• Aws
• S3

• S3

• Objects are replicated across at least 3 AZs in the AWS region
• Data is available within milliseconds
• Billed GB/m fee for data stored
• Billed $ per GB for transfer OUT (IN is free) and a price per 1,000 requests
• No specific retrieval fee
• No minimum duration
• No minimum size

• Same specs as S3 Standard, but object storage costs are significantly cheaper
• New cost component, which is a retrieval fee, in the form of a per GB data retrieval fee.
• Standard-IA has a minimum duration charge of 30 days - objects can be stored for less, but the minimum billing always applies
• Standard-IA has a minimum capacity charge of 128KB per object

• Same specs as S3 Standard-IA, but significantly cheaper
• One Zone-IA does not provide the multi-AZ resilience model of Standard or Standard-IA. Instead only one AZ is used within the region.
• Should only be used for non-critical or replaceable data

• Like S3 Standard-IA with regards to cheaper storage, but with more expensive retrieval and a longer minimum fee
• Minimum duration charge of 90 days
• Data is still redundantly stored across 3 AZ

• S3 Glacier objects cannot be made publicly available
• S3 Glacier objects are not immediately available, you have to initiate a retrieval job
• Once the retrieval job completes, you’ll find your object temporarily stored in the S3 Standard-IA storage class
• Data is still redundantly stored across 3 AZ
• Minimum duration charge of 90 days
• Minimum data size of 40 KB
• Ideal for situations where archival data is stored

The faster the retrieval job, the more expensive it is.

• Expedited (1-5 minutes)
• Standard (3-5 hours)
• Bulk (5-12 hours)

• 40 KB minimum size charge
• 180 day minimum duration charge

• Standard (12 hours)
• Bulk (up to 48 hours)

• Contains 5 tiers
  • Frequent Access - S3 Standard
  • Infrequent Access - S3 Standard-IA
  • Archive Instant Access - S3 Glacier Instant - Objects move here after 90 days
  • Archive Access - S3 Glacier Flexible (optional)
  • Deep Archive - S3 Glacier Deep Archive (optional)
• Intelligent Tiering monitors and automatically moves any objects not accessed for 30 days to a low cost infrequent access tier and eventually to archive instance access, archive access, or deep archive tiers
• A data tier management fee is applied when using S3 Intelligent Tiering.
• Only useful if retrieval patterns are changing constantly
