Traffic Policy

Available in Classic and VPC

A Traffic Policy is a load balancing policy that operates on incoming traffic. It stores load balancing algorithms and response resource information. By configuring health checks and backup resources for resources in a Traffic Policy, you can ensure service continuity.
You can create and manage Traffic Policies in the Traffic Policy menu.

Traffic Policy interface

Here is a basic overview of the Traffic Policy menu for using Global Traffic Manager.

1. Traffic Policy settings

Enter the Traffic Policy name and select the load balancing algorithm to apply.

1. Enter the Traffic Policy name.
2. Click the algorithm dropdown menu and select a load balancing algorithm.
   • Round Robin: Resources respond to requests sequentially.
   • Weight Based: Traffic is distributed based on the weight assigned to each resource.
   • Geolocation: Traffic is distributed based on the user's location.
   • CIDR: Traffic is distributed based on the user's IP address range.

2. Resource settings

Configure the responding resources according to the selected algorithm.

• When Round Robin or Weight Based is selected
• When Geolocation or CIDR is selected

When Round Robin or Weight Based is selected

When Round Robin or Weight Based is selected from the algorithm, configure the resources as follows:

1. Click the [Basic settings] or the [Advanced settings] tab to select whether to assign backup resources.
   • [Basic settings] tab: Do not assign backup resources.
   • [Advanced settings] tab: Assign backup resources. Health check settings are required (see 3. Health check settings).
2. Select a resource type and enter the resource according to the selected type.
   • Type: Click the dropdown menu and select a resource type.
     • External public IP: A public IP that was not created in the NAVER Cloud Platform.
     • External Domain: A domain that was not created in the NAVER Cloud Platform.
   • Health check Region: Enabled when the resource type is External Public IP. Click the dropdown menu and select a Region to support health checks.
   • Weight (%): When the Weight Based algorithm is selected, enter the weight for each resource.
     • Enter the total weight so that the sum equals 100.
   • : Click to add a resource input field.
   • : Click to delete a resource input field.
   • When the [Advanced settings] tab is selected, enter backup resources for each resource.

When Geolocation or CIDR is selected

When Geolocation or CIDR is selected from the algorithm, configure the resources as follows:

1. Click the [Basic settings] or the [Advanced settings] tab to select whether to assign backup resources.
   • [Basic settings] tab: Do not assign backup resources.
   • [Advanced settings] tab: Assign backup resources. Health check settings are required (see 3. Health check settings).
2. Click the Map selection dropdown menu and select the Geo/CIDR Map to apply.
   • [Create Map]: Click to create a Map (see Create Geo/CIDR Map).
   • : Click to refresh the Map list in the Map selection dropdown menu.
3. For each Zone/CIDR block, select a resource type and enter the resource.
   • Type: Click the dropdown menu and select a resource type.
     • External public IP: A public IP that was not created in the NAVER Cloud Platform.
     • External Domain: A domain that was not created in the NAVER Cloud Platform.
   • Health check Region: Enabled when the resource type is External Public IP. Click the dropdown menu and select a Region to support health checks.
   • When you hover over a Zone/CIDR block name, the region or IP address range assigned to the Zone/CIDR block is displayed.
   • When the [Advanced settings] tab is selected, enter backup resources for each resource.

3. Health check settings

Select whether to enable health checks.

• Disable: Select this option and click [OK] to complete Traffic Policy creation.
• Enable: Select this option and configure the health check.

To configure the health check and complete Traffic Policy creation:

1. Click the [Basic settings] or the [Advanced settings] tab to select the settings to configure.

   • [Basic settings] tab: Configure the access information for health checks.
   • [Advanced settings] tab: In addition to the access information, configure the health check interval, success threshold, and failure threshold.

2. Enter the health check configuration.

   • Protocol: Select the protocol to use for the health check. (Select among TCP, HTTP, or HTTPS.)
     • For HTTP/HTTPS, the health check is considered successful only when a 200 response is returned.
   • Port: Enter the port number to use for the health check.
   • Host Header/Path: Enter the request information to use for the health check.
     • This option is available only when the protocol is set to HTTP or HTTPS.
     • If not configured, the Host Header is set to the domain of the Traffic Profile, and the Path is set to "/."
   • When the [Advanced settings] tab is selected, enter the following values:
     • Health Check interval: Click the dropdown menu and select a health check interval.
