Distributed cloud storage technology

Traditionally, managing distant storage leads to silos and costly data copies.
Cubbit DS3 Composer unifies fragmented resources into one intelligent system.

Orchestrate distributed storage like a symphony.

One Swarm. One data domain.

DS3 Composer combines your storage resources into a single, geo-distributed cluster—the Swarm—transforming scattered storage into an organised, seamless data domain.

Flexible redundancy, zero waste.

Define custom redundancy rules, maximise the efficiency of existing hardware, and serve multiple workloads without waste.

Deploy S3 access anywhere.

Set up S3-compatible gateways wherever you need them — whether in the cloud, data center, or edge — and gain instant access to your unified data layer.

Security by design.

Every file is encrypted using keys you fully control (zero-knowledge/bring-your-own-keys), split...

... and geo-distributed. Secure by default.

Swarm intelligence and self-healing storage.

Storage nodes use swarm intelligence to automatically manage data distribution, redundancy, and self-repair according to your policies.

Even if entire nodes or regions go offline, your data remains safe. The Swarm instantly detects issues and autonomously initiates recovery.

Inside the engine room

Have a look over the features and components that define the Cubbit experience.

European sovereignty

Cubbit is the only 100% European proprietary object storage software.

Data localisation

Choose precisely where your data is located, ensuring compliance with GDPR and all regional regulations.

2X ransomware protection

Double your data security with client-side safeguards (object lock, versioning) and server-side defences (geo-distribution, encryption).

Geo-distributed by design

Data is encrypted (AES-256), fragmented, and replicated across multiple locations — safe from ransomware and disasters.

Multi-PB scalability

Scale up or down your storage in minutes, on demand, as your data needs change.

Greener: up to 50% less IT resources

Cubbit’s DS3 technology optimises resources, extending storage hardware lifespan, reducing electronic waste, and minimising your carbon footprint.

Business ready and easy to use

Full feature customisation

Customise redundancy, permissions, data localisation, and more. Design multiple SLA/price ratios from a single S3 solution.

Hardware agnostic

Run Cubbit on any system, whether it's bare metal, public cloud, or any hardware.

Re-use your HW and data centres

Ensure maximum flexibility and minimal investment by amortising your existing hardware and data centres.

Multi-tenant

Each tenant can be operated by a different user (or reseller), who has full control on metrics, configurations, reports, billing, and policies.

Edge gateways

Optimise performance, reduce latency, and position gateways at the edge or wherever required for enhanced efficiency.

White-label option

Personalise your cloud storage solution with your own brand to customise your offering.

Single data domain

Manage dispersed silos — across edge, on-prem, and cloud — under a single data domain.

Zero-knowledge

Integration with a private KMS ensures that only the user has access to the stored data.
