What is S3 object storage?

S3-style object storage is a scalable cloud storage model for files (objects) stored in buckets. It is commonly used for backups, media delivery, logs, archives, and app assets. Many providers offer S3-compatible APIs, so you can often switch vendors without changing your application too much.

How to reduce storage costs

  • Move rarely accessed files to archive/cold tiers.
  • Use lifecycle policies to automate tier transitions.
  • Compress files before upload when possible.
  • Delete orphaned/unused objects regularly.
  • Consider egress-heavy workloads separately (R2/Wasabi/DO may differ).

How to pick a provider

  • Backup/archive: prioritize storage price + retrieval frequency.
  • Media delivery: egress often dominates total cost.
  • App assets: check latency/region availability and API pricing.
  • Enterprise: compare SLA, compliance, IAM, and private networking.

Suggested next upgrades (for production)

  • Auto-sync prices from provider APIs / docs into a JSON source.
  • Region-based pricing tabs (US/EU/APAC).
  • Total cost calculator (storage + egress + operations + retrieval).
  • Provider badges, uptime/SLA comparison, and feature matrix.

FAQ

Quick answers users usually need before choosing cloud object storage.

What is usually the cheapest option?

Archive/cold tiers are typically the cheapest per GB, but they often include retrieval delays and/or retrieval fees. The “cheapest” provider depends on access pattern, not storage price alone.

Why can a more expensive storage tier cost less overall?

If your app downloads data frequently, outbound and retrieval charges can exceed the storage bill. In that case, a provider with higher storage price but lower egress fees may be cheaper overall.

Is S3 compatibility enough to migrate easily?

Usually yes for simple object operations, but differences may exist in IAM, ACLs, multipart upload behavior, lifecycle policies, and CDN integrations. Test your workload before switching.
