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

The following is how to create a Network Proxy Load Balancer.

  1. Access the NAVER Cloud Platform console.
  2. Click the Services > Networking > Load Balancer menu one by one in the order.
  3. Click the Load Balancer menu.
  4. Click the [Create Load Balancer] > [Create Network Proxy Load Balancer] button in the order.

  5. When the Create Load Balancer screen appears, proceed with the following steps.
Note

The 3. Certificate Settings stage only appears if you added Listener with TLS protocol in the 2. Create Load Balancer (Listener Settings) stage.
If you added listeners only with TLS protocol, the 3. Certificate Settings stage does not appear. Please proceed without the stage.

1. Create Load Balancer

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

loadbalancer-proxylb-vpc_create_ko

  • 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: 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.

  • For Singapore region, you can select the Subnet by the selected network type.

    • 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 further 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.

  • If you are in Singapore region and set the Network to Public IP, you can designate a fixed Public IP.

    • Official Certified IP: Select the same zone as the subnet and select the unused IP among the IPs you requested in the Public IP menu to assign it to Load Balancer. If you have no requested IP, you can select Request Official Certified IP to request anew.
    • You cannot select the same Public IP for different zones.
Caution

Once a public IP is set, it becomes fixed and can be used semi-permanently, but can't be changed.

2. Create Load Balancer (Listener Settings)

loadbalancer-proxylb-vpc_listener_ko

  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.
    • To add multiple listeners, repeat from the step 1 to 3.
    • In order to delete an added listener, click the [Delete] button.
  4. Click the [Next] button.

3. Certificate Settings

Note

The Certificate Settings stage only appears if you added Listener with TLS protocol in the 2. Create Load Balancer (Listener Settings) stage.

loadbalancer-proxylb-vpc_certificate_ko

  1. Select the suitable certificate for the service among the certificates registered in the Certificate Manager.
  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 the Cipher Suite setting.
    • 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.
Caution

The bandwidth of Load Balancer Subnet must be added to ACG of the bound server and NACL as an access source and allowed port.
