Overview

Basic traffic throttling plugin is a powerful traffic throttling component provided by API Gateway. It can throttle traffic in three dimensions of API, application, and client IP by second, minute, hour, or day. You can create a basic traffic throttling plugin and bind it to your API to take effect and protect your backend services.

Directions

Step 1. Create a plugin

1. Log in to the API Gateway console.
2. On the left sidebar, click Plugin to enter the plugin list page.
3. Click Create in the top-left corner of the page and select Basic Throttling as the plugin type to create a basic traffic throttling plugin.

Step 2. Bind an API and make the plugin effective

1. Select the just created plugin in the list and click Bind API in the Operation column.
2. In the Bind API pop-up window, select the service, environment, and the API that needs to be bound to the plugin.
   
3. Click OK to bind the plugin to the API. At this time, the configuration of the plugin has taken effect for the API.

Notes

The basic traffic throttling plugin will be affected by service traffic throttling and API traffic throttling. If multiple traffic throttling rules take effect at the same time, the lowest threshold will prevail.
For example, if the traffic throttling threshold of an API is set to 500 QPS in the basic traffic throttling plugin, the traffic throttling threshold of the service to which the API belongs is 100 QPS, and the traffic throttling threshold of the API itself is 50 QPS, then the actually effective threshold is 50 QPS.
