Disaster Recovery

Your KEC instances are deployed on different physical servers to further ensure the high availability of services.

Multiple Availability Zones

Fault isolation among availability zones is provided to ensure continuous business, achieving high availability of services in the same region.

Features

Disaster Tolerance Group

KEC instances are physically dispersed to ensure high availability. You can add or remove an instance at any time.

Quick Creation

You can create KEC instances with a few simple operations and start a hundred KEC instances in minutes.

Flexible Upgrade

You can upgrade the CPU, memory, and disk configurations of your KEC instances at any time.

Backup and Recovery

You can back up data in your system and data disks and recover data from backups.

Private Network

Scenarios

General scenario

Professional Scenarios

High I/O Scenarios

General scenario

Official websites, lightweight web applications, and small databases

Deployment Suggestion

Web services, applications, and databases that have general requirements for CPU, memory, and bandwidth can first be deployed on one or a few KEC instances. As your business grows, you can either add more KEC instances or upgrade the configurations of the current instances at any time to handle data requests during business surges.

Professional Scenarios

Websites and applications that offer rich media content.

Deployment Suggestion

Pair KEC with Kingsoft Cloud Standard Storage Service (KS3). KEC hosts websites and applications that contain tons of images and videos. KS3 stores static images, videos, or downloadables. This combination enables storage of massive data at low costs. In addition, activate Kingsoft Cloud Content Delivery Network (CDN) and Server Load Balancing (SLB) to cut down user access latency, reduce bandwidth costs, and improve availability.

High I/O Scenarios

High I/O applications such as self-built databases.

Deployment Suggestion

Create an I/O Optimized KEC instance that has high specifications and use it with local SSDs and SLB to ensure fast response to high I/O concurrency with higher data reliability and service availability.
