1. AWS vs. Azure vs. Google Cloud: Feature Comparison
All three providers dominate the enterprise cloud storage market, but their strengths differ.
Performance Benchmarks (2025 Data)
| Provider | Max IOPS | Latency (ms) | Data Redundancy |
|---|---|---|---|
| AWS S3 | 55,000 | 12 | 11 9’s (99.999999999%) |
| Azure Blob | 50,000 | 15 | 10 9’s |
| Google Cloud Storage | 60,000 | 10 | 11 9’s |
AWS Pros:
✅ Highest durability (99.999999999%)
✅ Best for hybrid cloud (via AWS Storage Gateway)
Azure Pros:
✅ Deep Microsoft 365 integration
✅ Best compliance (FedRAMP High, HIPAA)
Google Cloud Pros:
✅ Lowest latency (AI/ML optimized)
✅ Best pricing for archival data
2. Enterprise Cloud Storage Pricing (100TB+ Analysis)
Costs vary dramatically based on access frequency and region.
