Why AIStor is Different
Organizations need S3 compatibility on-premises but face a trade-off: public cloud means egress costs, data sovereignty concerns, and vendor lock-in. Traditional on-prem storage delivers partial S3 support, forcing code rewrites and fragmented operations across multiple components. AIStor eliminates that trade-off entirely.
Full API Parity
Complete AWS S3 compatibility with zero code changes required for migration.
Zero Egress Fees
Keep data on-premises and eliminate cloud data transfer costs.
One Unified Architecture
Purpose-built design delivers consistent performance without bolted-on components.
Any Deployment Model
Run on-premises, private cloud, or hybrid with the same S3 interface everywhere.
Business Impact
Accelerated Migration
Lift-and-shift S3 applications to on-premises without code changes—weeks instead of months.
Reduced Cloud Costs
Eliminate public cloud egress fees and unpredictable storage expenses.
Data Sovereignty
Maintain complete control over data location and residency for regulatory compliance.
Hybrid Flexibility
Connect private, public, and edge environments with a unified S3-compatible data layer.
