Data lakes grow over time, and data access frequency changes. Today we cover S3 storage classes, lifecycle policies, and cost optimization using Intelligent-Tiering.
S3 offers multiple storage classes based on access patterns and costs.
| Class | Purpose | Characteristics |
|---|---|---|
| S3 Standard | Frequently accessed hot data | Highest storage cost, no retrieval fee |
| S3 Standard-IA | Infrequent access (< once/month) | Low storage, retrieval cost, minimum 30 days |
| S3 One Zone-IA | Reproducible non-critical data | Single AZ, cheaper than IA, lower availability |
| S3 Glacier Instant Retrieval | Quarterly access, instant retrieval needed | Cheaper than IA, millisecond retrieval |
