Frequently Asked Questions

Cloud storage costs include: storage capacity ($/GB/month), data transfer out (egress fees), API operations (PUT/GET requests), and optional features like versioning or replication. This calculator estimates all components.

S3 Standard costs more per GB ($0.023/GB) but has no retrieval fees—best for frequently accessed data. S3 IA costs less ($0.0125/GB) but charges per retrieval—best for backups accessed monthly.

Egress fees are charges for data leaving the cloud provider's network. AWS/Azure/GCP charge $0.05-0.12/GB for downloads to the internet. Transfers within the same region are usually free.

AWS S3 charges ~$0.005 per 1,000 PUT/POST and $0.0004 per 1,000 GET requests. Azure/GCP have similar pricing. High-frequency applications can accumulate significant operation costs.

Depends on usage. AWS Glacier is cheapest for archives ($0.004/GB/month). Google Cloud is competitive for standard storage. Azure offers good pricing with commit discounts. Compare all costs including egress.

Storage classes optimize cost vs access speed. Use Standard for active data, Infrequent Access for monthly backups, Archive/Glacier for long-term retention. Choose based on access frequency and retrieval time tolerance.

Use lifecycle policies to move old data to cheaper tiers. Enable compression. Delete unused data and old snapshots. Use reserved capacity for predictable workloads. Minimize egress by processing data in-region.

On-demand has no commitment but costs more. Reserved capacity requires 1-3 year commitment for 30-50% discounts. Use reserved for known baseline storage, on-demand for variable workloads.

Yes: early deletion fees (deleting IA/Archive data before 30-90 days), request fees for listing/metadata, cross-region replication, versioning storage, and monitoring/logging. Read the fine print.

Track how often users download files. Example: 1,000 users downloading 100MB each = 100GB egress = $5-12/month. CDN caching can reduce egress by 70-90% for static content.
