Create and manage network proxy Load Balancer

Available in VPC

Network Proxy Load Balancer is a load balancer using a similar method to the load balancer provided in the Classic environment. With the Proxy method of communication, it offers the same load balancing algorithm as Application Load Balancers.

Create Network Proxy Load Balancer

To create a Network Proxy Load Balancer, follow these steps:

1. In the VPC environment of the NAVER Cloud Platform console, navigate to > Services > Networking > Load Balancer.
2. Click the Load Balancer menu.
3. Click [Create load balancer] > [Create Network Proxy Load Balancer] in order.
4. When the Create load balancer page appears, proceed with the following steps in order:
   • 1. Create load balancer.
   • 2. Create load balancer (set listener).
   • 3. Set certificate.
   • 4. Select target group.
   • 5. View setting information.

1. Create load balancer

Enter the information for the Network Proxy Load Balancer you wish to create and click the [Next] button.

• Network: select the network type for the load balancer.

  • Private IP: it processes the load balancing from the internal server using a Private IP within VPC. It cannot be accessed from outside VPC.
  • Public IP: the Public IP is set to allow calling from outside VPC or the Internet. It processes the load balancing, and you can utilize it by connecting with the domains or CDN services of customers using the random domain provided with the Public IP.

• Load processing capacity: select the size of the load balancer depending on the load processing capacity.

  • You can select a Small, Medium, Large, or Extra-large option based on the load processing capacity.
  • Each size can handle at least 30,000/60,000/90,000/120,000 loads, respectively, based on connections per second (CPS).
  • Due to SSL offloading, TLS is expected to have roughly 1/10th of the capacity compared to TCP, although this can vary based on the authentication key method and size.

• Target VPC: select the VPC to create a load balancer in.

• Select subnet: select the zone and subnet to use to create the load balancer.

  Caution

  • The selected zone and subnet cannot be changed after the load balancer creation is completed.
  • Create and select a dedicated subnet.
  • You can only select the subnet included in the VPC you selected from Target VPC.
    • If you select Private IP, you can only select the subnet created with a Private IP Load Balancer Subnet.
    • If you select Public IP, you can only select the subnet created with Public IP Load Balancer Subnet.
    • For more information on how to create subnets, see Create subnet.
  • You do not need to create separate subnets for each load balancer; however, we recommend using a Class C subnet (255.255.255.0) size.

• Public IP: select a Public IP that you possess or subscribe to a new Public IP.

2. Create load balancer (set listener)

1. Select the protocol (TCP/TLS) that the basic listener of the load balancer will operate with.
2. Set up the port to which the basic listener of the load balancer will bind.
3. Click the [Add] button.
   • A listener is added.
   • Repeat steps 1 to 3 to add multiple listeners.
   • To delete an added listener, click the [Delete] button.
4. Click the [Next] button.

3. Set certificate

1. Select the appropriate certificate for the service from those registered in Certificate Manager.
   • If you have no registered certificate, see Certificate Manager user guides to register a certificate.

2. Select the TLS protocol version at the TLS minimum support version.
   • You can select from TLSv1.0, TLSv1.1, TLSv1.2, and TLSv1.3.
3. Select the cipher suite that the TLS listeners will support in Set cipher suite.
   • You can select the encryption feature for the load balancer to provide at the encryption negotiation with the client.
   • You can select Select All to select all cipher suites available.

4. Select target group

Select the target group to apply load balancing and click the [Next] button.

• To do this, the target group must be created in advance. If there is no created target group, click the [Create target group] button to create a target group. (See Create target group)
• Among target groups created, only target groups that can be connected are displayed.
  • You can only select a target group created with PROXY_TCP protocols for Network Proxy Load Balancers.

5. View setting information

View the setting information for the load balancer and click the [Create load balancer] button.

Manage Network Proxy Load Balancer

You can change the load balancer, subnet, and listener setting for the created Network Proxy Load Balancer and check the monitoring information as a graph.

Set load balancer

To view the setting information and change the setting for the load balancer, follow these steps:

1. In the VPC environment of the NAVER Cloud Platform console, navigate to > Services > Networking > Load Balancer.

4. After applying changes, click the [OK] button.

   • You can change load processing capacity.
     • You can select a Small, Medium, Large, or Extra-large option based on the load processing capacity.
     • Each size can handle at least 30,000/60,000/90,000/120,000 loads, respectively, based on connections per second (CPS).
   • Due to SSL offloading, TLS is expected to have roughly 1/10th of the capacity compared to TCP, although this can vary based on the authentication key method and size.
   • You can change the Idle Timeout.
