Multiple certificates usage

Available in VPC

Application Load Balancer and Network Proxy Load Balancer support the SNI-based multiple certificate feature.

• You set the default certificate by selecting it when you create a listener.
• When a client sends a request, you check SNI and use either an additional certificate or the default certificate.
• You also use the default certificate when the client does not support SNI.
• You can configure multiple certificates for a single domain.
• You can configure up to 25 additional SSL/TLS certificates per load balancer.
• You can add only certificates registered in the Certificate Manager service.

Configure additional certificates

To configure additional certificates:

1. In the VPC environment of the NAVER Cloud Platform console, navigate to Menu > Services > Networking > Load Balancer.
2. Select the load balancer that you want to use multiple certificates with, and then click [Change listener settings].
3. Select a listener that uses the HTTPS/TLS protocol, and then click [Change Certificate].
   Note

   You can use [Change Certificate] only when you select an HTTPS/TLS listener on an Application Load Balancer or a Network Proxy Load Balancer.

4. Select the additional certificate and click [Add].
