Why Choose CDS?
Cloud Disk Server is a low-latency, durable, highly reliable, and elastic block storage service provided by Baidu AI Cloud for BCC. Data in Cloud Disk Server is stored with multi-replica redundancy within the availability zone to eliminate single-point failure risks, while also enabling elastic management through online resizing and modifications of disk types.
Flexible Charging
It supports flexible switching between prepay and postpay, provides renewal reminders and data retention mechanisms, allows charges for snapshots on a pay-as-you-go model, and efficiently manages these through snapshot chains, enabling precise control over costs and resources.
Disk Management
Allows for the creation of cloud disks either alongside instances or independently, offering the flexibility to attach them to cloud servers; includes a disk encryption feature to safeguard system and data disks, fulfilling enterprise-level storage requirements.
