Block storage as a stable, recoverable business foundation
Cloud Disk provides persistent block storage independent of instance lifecycle, attachable to instances and bare metal, and combined with snapshot, clone and backup policies to give databases, virtualization and critical volumes stable, low-latency, predictable storage.
Key advantages
Low latency and predictable performance
Stable IOPS and throughput for transactional and high-concurrency workloads, reducing jitter.
- Stable IOPS
- Predictable latency
- For database volumes
- High-concurrency support
Snapshots, clones and backups
Volume snapshots, fast clones and scheduled backups for rollback, replication and DR.
- Volume snapshots
- Fast clones
- Scheduled backups
- Business rollback
Online resize
Expand volume capacity without interrupting the business, handling data growth smoothly.
- Elastic capacity
- No-downtime resize
- Pay as you go
- Simpler capacity planning
Deep integration with compute
Attach to instances and bare metal, managed uniformly via console and API.
- Instance system / data disks
- Bare-metal attachment
- Container persistent volumes
- Unified API management
Typical scenarios
