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. Access NAVER Cloud Platform console.
2. Click Services > Networking > Load Balancer, in order.
3. Click the Load Balancer menu.
4. Click [Create Load Balancer] > [Create Network Proxy Load Balancer] in order.
5. When the Load Balancer creation screen 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 Load Balancer.

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

• Load control capacity: select the size of the Load Balancer depending on the load control capacity.

  • You can select Small/Medium/Large considering the load control capacity.
  • Each size can handle at least 30,000/60,000/90,000 loads, respectively, based on connections per minute (CPS).
  • TLS is an SSL Offloading. 1/10 of TCP’s capacity is expected, however, it may vary by the authentication key method or 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 creating the Load Balancer.
  • Create and select a dedicated Subnet. If the Load Balancer is located in the same Subnet with the server, it does not process the load to the server.
  • You can only select the Subnet included in the selected VPC you chose as Target VPC.
    • If you chose Private IP, you can only select the Subnet created with a Private IP Load Balancer Subnet.
    • If you chose Public IP, you can only select the Subnet created with Public IP Load Balancer Subnet.
    • For more information about creating Subnets, see create Subnet.
  • You do not need to create separate Subnets for each Load Balancer, however, we recommend a Subnet in the C Class (255.255.255.0) scale.

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

2. Create Load Balancer (set listener)

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

3. Set Certificate

1. Select the suitable certificate for the service among the certificates registered in Certificate Manager.
   • If you have no registered certificate, see Certificate Manager user guide to register a certificate.

2. Select the TLS protocol version at TLS minimum support version.
   • You can select from TLSv1.0, TLSv1.1, and TLSv1.2.
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 division and click the [Next] button.

• To do this, the Target Group need to 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

Check the setting information for Load Balancer and click the [Create Load Balancer] button.
