Overview

EdgeOne Load Balancer is ideal for scenarios where high availability of origins is crucial. It supports the configuration of multi-level secondary sources for disaster recovery switching. It can proactively probe the health status of origins. This proactive measure blocks failed origins and directs business traffic to healthy origins.
Note:
EdgeOne Load Balancer feature is in beta testing. If you want to use it, you can Contact Us.

Use Cases

Hardware failures, network failures, configuration errors, security attacks, natural disasters, human errors, and other unforeseen circumstances, can affect the availability of the origin. For businesses that require high availability, such as finance, gaming, audio and video, and e-commerce, even brief failures of the origin can result in significant losses. Therefore, it is necessary to implement primary/secondary disaster recovery and health checks for the origin.
Primary/Secondary Disaster Recovery: When the primary source becomes unavailable, it is automatically switched to the secondary source to ensure business continuity.
Proactively Checking origin Health Status: Preemptively disables failed origins, and redirects business traffic to healthy origins. Prevents a situation where a significant number of legitimate service requests are still directed to malfunctioning origins in the event of a failure.

Supported Capabilities

1. Supports the configuration of multi-level secondary sources for multi-source disaster recovery.
2. Supports the configuration of health check policies such as ICMP Ping, HTTP/HTTPS, TCP, and UDP to preemptively disable failed origins and redirect business traffic to healthy origins.
3. Provides a fallback retry policy. It retries directing the traffic to alternative healthy origins when real business traffic requests fail.
