Edge Security Acceleration (ESA) uses the origin pool feature to intelligently distribute and manage traffic at points of presence (POPs), ensuring even distribution of traffic and optimizing resource utilization. This not only improves service availability and reliability but also enhances overall network performance and user experience.
Feature overview
ESA can steer traffic among origin servers in a pool based on their weights. Origin pools can be referenced by ESA-covered domains and TCP/UDP proxied applications. By integrating origin pools with load balancing, you can flexibly and intelligently steer traffic to reduce origin load and boost your service availability.
Create origin pools
Log on to the ESA console.
On the Websites page, find the website that you want to manage, and click the website name or View Details in the Actions column.
In the left navigation bar, select .
On the Origin Pools Management page, click Create Origin Pool.
On the Create Origin Pool page, enter the Pool Name and add Origin Servers.
Parameter | Description |
Pool Name | The name of the origin pool. The pool name is automatically appended as part of the hostname of the origin pool. |
Domain Name | The hostname is automatically generated in the following format: poolName.origin-pool.yourWebsiteDomainName |
Origin Server - Name | You can enter a custom name for the origin server. |
Origin Server - Type | Select the type of the origin server.
|
Origin Server - Origin Server Address | The address of the origin server. |
Origin Server - Weight and Percentage | Valid values: 0 to 100. Default value: 50. The minimum step size for weight adjustments is 1. The system calculates a percentage value based on your configured weight. This percentage indicates the proportion of traffic distribution for your reference. Note A weight of 0 indicates that no requests are sent to the origin server. |
Origin Server - Origin Host Header | Configure the Host header included in the request to the origin server. |
Click Add to add the next origin server information.
After adding all the origin server information, click Confirm to complete the creation of the origin pool.
Delete origin pools
Before deleting an origin address, delete the origin pool from the load balancer. For more information, see Remove origin pools referenced by a load balancer.
Log on to the ESA console.
On the Websites page, find the website that you want to manage, and click the website name or View Details in the Actions column.
In the left-side navigation tree, choose .
Click Delete for the origin address you want to delete.
