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.
