Cloud Block Storage inconsistency

Block storage is offered as a service by all major cloud providers. But it these services differ between cloud providers and lack features that are available on on-premises block storage, such as storage efficiencies, built-in data resilience, replication and cloning tools.


Centralized, cost effective and resilient

Cloud Volumes ONTAP provides centrally managed high-performance block storage with enhanced resilience delivered natively on AWS, Google Cloud and Azure. Simply attach Cloud Volumes ONTAP block storage to one or multiple cloud-based applications, databases and containers and get built-in backup, security, and performance monitoring. Cloud Volumes runs within your VPC/VNet and utilizes cloud disks (block) and buckets (object) to optimize performance while reducing storage costs.
