Elastic Block Storage
Elastic Block Storage (EBS) is a block-level data storage service provided for Kingsoft Cloud Elastic Compute (KEC) instances. It can be connected to any running KEC instance in the same data center. EBS 3.0 is the latest generation of block storage system independently developed by Kingsoft Cloud. It features high availability, high reliability, flexibility, ease of use, and elastic capacity expansion, and supports snapshots and custom images.
Benefits
Elastic Expansion
Up to eight EBS volumes can be attached to a KEC instance, and the maximum capacity of an EBS volume is 32 TB.
Multiple Types
EBS provides EHDD volumes and SSD volumes to meet different performance requirements.
High Reliability
The triplicate storage architecture provides 99.9999999% data reliability.
High Performance
An SSD volume provides 30 random IOPS per GB, up to 25,000 IOPS, and 256 MB/s throughput. The latency of an SSD volume is less than 2 ms.
Data Backup
Local snapshots and normal snapshots are supported. Snapshot-based backup reduces the risk of data loss.
Features
Quick Creation
You can create KEC instances and purchase EBS volumes with a few simple operations.
Flexible Expansion
You can flexibly add, delete, or expand the capacity of EBS volumes to adapt to different business requirements.
Easy Management
You can manage EBS volumes by using the EBS console, API, or command line interface (CLI).
Snapshots
Snapshots are supported to avoid data loss due to accidental deletions, tampering, and virus attacks.

Enterprise Office Application
EBS is loosely coupled with KEC for fast online and offline migration and business recovery. EBS offers a complete set of data backup, snapshot, and data recovery capabilities. It is applicable to high-load core business systems, and can meet the need of enterprises for elastic and reliable large-capacity block storage.
Development and Testing
You can use EBS to deploy the development and testing applications.
Development and Testing
You can use EBS to deploy the development and testing applications. We recommend that you use general-I/O EBS volumes to meet the development, testing, deployment, and O&M requirements.
NoSQL/Relational Databases
Databases such as Oracle, SQL Server, and MySQL
NoSQL/Relational Databases
With the high-performance NVMe SSD volumes and distributed architecture, EBS provides ultra-high performance and reliability for database applications to meet the requirements for low latency and high performance.
