How does DeltaGlider reduce an Amazon S3 bill during migration?

DeltaGlider combines two levers: a lower-cost S3-compatible backend such as Hetzner Object Storage or Wasabi, and transparent delta compression for repeated binary artifacts.

Does DeltaGlider replace Amazon S3 enterprise controls?

For app-facing S3 workflows, DeltaGlider provides IAM users and groups, S3 access keys, OAuth/OIDC mapping, ABAC policies, bucket policy, public prefixes, quotas, replication, metrics, audit, and operator UI. It is not a full replacement for every AWS-native lifecycle or Object Lock feature.

Are request, egress, and retrieval fees included in the calculator?

No. The calculator models storage capacity only so the storage-price and compression levers are visible. Real migration analysis should include request profile, egress, support plan, minimum storage duration, tax/VAT, and provider-specific limits.

Amazon S3 migration economics

Move Amazon S3 data to Hetzner or Wasabi.Keep the enterprise control plane.

DeltaGlider sits between existing S3-compatible clients and lower-cost object storage. The migration thesis is simple: cheaper backend bytes plus delta compression, without giving up IAM, OAuth, quotas, replication, audit, metrics, and operator UI.

Migration shape

Do not replace Amazon S3 with a cheaper bucket. Replace the missing control plane.

Hetzner and Wasabi can make object storage cheaper. DeltaGlider is the policy and operations layer that makes the migration usable for production teams.

Step 01

Keep S3-compatible clients

Applications, CI, backup tools, and SDKs keep using the S3 API. Point them at DeltaGlider instead of Amazon S3.

Step 02

Move bytes cheaper

DeltaGlider writes to Hetzner or Wasabi behind the scenes, using the backend economics you choose.

Step 03

Replace the control plane

IAM, OAuth, bucket policy, quotas, replication, metrics, audit, and operator workflows live in DGP.

Step 04

Compress repeats

Repeated artifacts, archives, builds, dumps, and model variants can shrink further through delta storage.

Inputs

Source data in Amazon S3100 TB

Delta compression savings80%

50% means stored bytes are half of source. 99% means the backend stores 1% of the repeated artifact stream.

Feature replacement

Amazon S3 enterprise feature map.

DGP does not try to clone every AWS storage class. It replaces the operational controls you lose when moving app-facing S3 API workloads to a cheaper S3-compatible backend.

Keep nativeUse backend

When it works

Best fit: hot S3 API workflows with repeated binary structure.

The largest reductions come when both levers fire: the backend is cheaper per TB and the data stream has repeated archive/build/dump/model bytes.

Artifact and build retention

CI outputs, release zips, package catalogs, installers, and archive bundles usually keep many adjacent versions.

Backup and dump streams

Daily archives and database dumps often repeat most internal structure while still needing full-object reads.

Model and asset variants

Fine-tuned checkpoints, game assets, and generated media bundles can be binary-similar across variants.

Not modeled here: egress, request pricing, retrieval fees, storage-class minimum durations, object-lock requirements, support plans, tax/VAT, and provider-specific limits. Use this page as the fast economic screen, then run a sizing pass on your real object stream.

Next step

Bring one AWS bill and one object sample.

We can model backend price, compression ratio, request profile, egress, and which Amazon S3 controls must move into DeltaGlider before migration.
