# Creating and managing Inline Load Balancer

Available in VPC

Inline Load Balancer is a Load Balancer that operates in the Inline manner in which network packets must be transferred without tampering. It is mainly used to configure the network interfaces of security appliances that operate in the Inline mode in the form of cluster. To ensure the stability of security appliances, use them with an Inline load balancer.

              Note

              

For the complete SFC configuration scenario, see [SFC (Service Function Chain) scenarios](/docs/en/vpc-sfcprocedure-vpc).

## Create Inline Load Balancer

To create an Inline Load Balancer, follow these steps:

1. In the VPC environment of the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Networking** > **Load Balancer**.
2. Click the **Load Balancer** menu.
3. Click **[Create Load Balancer] > [Create Inline Load Balancer]** in order.
4. When the create Load Balancer screen appears, proceed with the following steps in order:
  - [1. Create Load Balancer](/docs/en/loadbalancer-inlinelb-vpc#1%EB%A1%9C%EB%93%9C%EB%B0%B8%EB%9F%B0%EC%84%9C%EC%83%9D%EC%84%B1)
  - [2. Select Target Group](/docs/en/loadbalancer-inlinelb-vpc#2TargetGroup%EC%84%A0%ED%83%9D)
  - [3. View setting information](/docs/en/loadbalancer-inlinelb-vpc#3%EC%84%A4%EC%A0%95%EC%A0%95%EB%B3%B4%EB%B3%B4%EA%B8%B0)

### 1. Create Load Balancer

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

- **Network**: The fixed network type of Load Balancer is Private IP.
  - **Private IP**: it processes the load division from the internal server using a Private IP within VPC. It cannot be accessed from outside.
- **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.

              Note

              

- Make sure you create a private LB subnet before selecting the zone and subnet to create a Load Balancer.
- The selected Zone and Subnet cannot be changed after creating the Load Balancer.

### 2. Select Target Group

Select the Target Group to apply load balancing and click the **[Next]** button.

- To do this, the Target Group need to be created in advance. If a Target Group created does not exist, click the **[Create Target Group]** button to create a Target Group. (See[Create Target Group](/docs/en/loadbalancer-targetgroup-vpc#TargetGroup%EC%83%9D%EC%84%B1))
- Among Target Groups created, only Target Groups that can be connected are displayed.
  - Only Target Groups with the protocol type set to IP are displayed for Inline Load Balancers.

              Note

              

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

### 3. View setting information

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

## Manage Inline Load Balancer

You can view the monitoring information of the Inline Load Balancer created in a graph.

              Note

              

You can change the NIC applied to Load Balancer in the **Target Group** menu. For more information, see [Target setting](/docs/en/loadbalancer-targetgroup-vpc#Target%EC%84%A4%EC%A0%95).

### Network Load Balancer monitoring

You can check the regularly collected information for Concurrent connection, Connection per Second, and Traffic In for the selected period each as a graph. To check the monitoring information of the Inline Load Balancer, follow these steps:

1. In the VPC environment of the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Networking** > **Load Balancer**.
2. Click the **Load Balancer** menu.
3. Select a Load Balancer to monitor and click the **[Monitoring]** button.
  - The basic monitoring popup window for the Load Balancer pops up and shows the monitoring information as graphs.
  - Select the period to check the monitoring information collected for the selected period.
  - Click the **[Refresh]** button to refresh the graphs.
  - Click the **[□]** button to view an extended graph and click the **[x]** button to download the collected monitoring information as an Excel file.

              Note

              

The collection cycle varies, depending on the selected period. Monitoring information collected by handling load balancing can be set up and checked from at least 1 minute to last year.

| Aggregation cycle (Interval) | Search Period |
| --- | --- |
| 1-minute cycle | Up to 6 hours |
| 5-minute cycle | Up to 1 day |
| 30-minute cycle | Up to 1 week |
| 2-hour cycle | Up to 1 month |
| 1-day cycle | 1 month exceeded |

## Delete Inline Load Balancer

To delete a Network Load Balancer, follow these steps:

1. In the VPC environment of the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Networking** > **Load Balancer**.
2. Click the **Load Balancer** menu.
3. Select a Load Balancer to delete and click the **[Delete Load Balancer]** button.
4. Check the content in the delete Load Balancer popup window and click the **[Delete]** button.
  - The selected Load Balancer is deleted.
