Storage Types: Block, File, & Object

Storage types represent distinct data models, from raw sector block arrays to shared NFS files and flat key-value HTTP buckets:

• Storage Paradigm Classifications Matrix: Comparing the structural dimensions:

• Distributed File Systems: GFS & HDFS: High-scale cluster filesystems.
• RAID & Durability Basics: Low-level disk reliability designs.
• Write-Ahead Logging (WAL) & Data Durability: Streaming database updates directly onto block partitions.

S3 Object Lifecycle Policies (Cloud Budget Economy)

For massive, high-volume analytics systems, static assets and log files accumulate rapidly. Retaining all raw files inside primary High-Performance Object storage tiers forever wastes immense budget resources.

**Solution: Dynamic Tiered Lifecycle Transitions**

1. Active Tier (0 - 30 days): Store new logs inside standard S3 buckets for instant sub-second retrieval.
2. Infrequent Access Tier (30 - 90 days): Automatically transition logs to **S3-IA** (Infrequent Access) to cut hosting costs by 50% (introduces small retrieval fees).
3. Glacier Archive Tier (90 - 365 days): Transition logs to **S3 Glacier Flexible** for long-term backups (reduces storage costs by 80%, retrieval takes 1-5 hours).
4. Permanent Deletion (365+ days): Configure strict deletion policies to purge expired log files, keeping storage footprint bounded.
