What Is Wasabi and What Does the Wasabi Cloud Storage Service Do?

Wasabi is a cloud object storage service positioned as "the AI storage cloud without the hyperscaler tax." It stores data on S3-compatible infrastructure and charges a flat per-TB rate for storage, with no fees for egress, API requests, or data retrieval. It fits workloads where data needs to stay hot and move freely — AI training data, backups, and long-term archives — and where unpredictable transfer or access fees are a concern.

The core idea: pay for storage, not for access

Wasabi's pitch is that nearly half of hyperscaler storage cost comes from fees rather than storage itself — egress, API requests, and retrieval charges that compound at scale. Wasabi's model is one flat per-TB rate with no surprises, and it states there are no fees for egress or API requests.

Two practical consequences follow from that:

• Data stays "hot" by default. There are no cold tiers, rehydration waits, or retrieval penalties, so archived data is accessible immediately rather than after a restore delay.
• Data can move without a meter running. You can pull data out to another platform, a GPU cloud, or on-prem hardware without egress charges, which reduces lock-in.

What it's used for

Wasabi groups its use cases into three areas, and the same architecture underlies all of them.

AI data storage

Store training datasets, model checkpoints, inference logs, and vector embeddings. The storage layer is independent of compute, so you can connect it to any GPU cloud or compute environment. It's S3-compatible and works with tools like MLflow, LangChain, and major AI frameworks, and supports RAG pipelines and vector embedding storage.

Cyber resilience and backup

Immutable, air-gapped storage designed to resist ransomware. Features include object-lock immutability and Covert Copy multi-user authorization (MUA). It integrates with backup platforms such as Veeam, Commvault, Rubrik, and Cohesity. Because there are no retrieval or recovery fees, restoring after an incident doesn't add cost.

Long-term retention and archiving

Archive data with no cold-tier penalties or access delays, with immutability for regulatory holds, legal discovery, and audit-ready retention. Wasabi cites SOC 2, ISO 27001, HIPAA, and GDPR compliance.

Key characteristics at a glance

How to decide if it fits

Wasabi is worth evaluating when your workload involves large volumes of data that you need to keep accessible and move between systems — AI pipelines, backup targets, or compliance-driven archives — and when per-request or egress fees are a meaningful line item in your current bill.

It's less obviously a fit if you depend on deep integration with a specific hyperscaler's native services beyond S3-compatible storage, or if your data is genuinely cold and rarely touched, where a cold-tier price might beat a flat hot-storage rate.

To check fit concretely: estimate your stored volume in TB, your monthly download percentage, and your API request volume, then compare a flat per-TB rate against your current storage-plus-fees total. Wasabi offers a free trial and a savings calculator on its site for exactly this comparison.
