Creating and Managing NLB

Network load balancer (NLB) operates at the transport layer (Layer 4) of the OSI model. An NLB's Listener can use TLS, TCP, or UDP protocols and is associated with a single default target group. All incoming traffic through the Listener is routed to the default target group.
The methods for creating, listing, monitoring, modifying, and configuring Security Groups for an NLB are as follows:

Create load balancer​

To create an NLB, follow these steps:

  1. Go to KakaoCloud Console > Beyond Networking Service > Load Balancing > Load Balancer.

  2. Click the [Create load balancer] button at the top right.

  3. In the Create load balancer screen, select the NLB(Network Load Balancer) type.

  4. Enter the settings and click the [Create] button. If additional Listeners are needed, you can click the [Add new listener] button to create up to 150 Listeners per project.
