Service Overview

The Load Balancer (LB) service of Samsung Cloud Platform automatically distributes traffic to available servers when there is an unpredictable traffic surge or server failure, ensuring the stability and continuity of customer services.

A Load Balancer serves as the service endpoint provided to clients, is deployed in a VPC subnet according to the service type (L4 / L7), and you can configure multiple services by adding listeners to the created Load Balancer.

The Listener receives client requests through the service port and processes traffic according to routing rules. L4 supports TCP / UDP / TLS protocols, and L7 supports HTTP / HTTPS protocols; in L7, you can specify an LB server group for each routing condition or set a redirect response for the request URL.

The LB server group forwards requests received by the Listener to specific servers based on load balancing and health checks. The servers receive client requests from the Load Balancer’s Source NAT IP through the ports configured for the members, and the server status is periodically monitored by the Load Balancer’s health check IP.

LB health check defines the member health check method registered in the LB server group. You can select a default LB health check resource provided for the LB server group, or create a new one to configure monitoring suitable for the application.

Features

• Various load balancing methods: Round Robin, Least Connection, IP Hash, etc., are provided.
• SSL Authentication Encryption and Offloading: Supports SSL offloading and allows selection of encryption level.
• Enhanced Security: Use a firewall to manage Load Balancer communication and view connection logs by storing logs.

Provided features

• Load Balancer: Select the service type and configure the IP to be used by the Load Balancer.
• Listener: Set the protocol, port, and routing rules. You can add multiple Listeners to a single Load Balancer.
• LB server group: Sets the load balancing method. LB server group can be attached to a single Load Balancer.
• Member: Select the server to add to the LB server group. You can choose Virtual Server or Bare Metal Server resources created in the same VPC as the Load Balancer, or enter an IP address directly.
• LB health check: Sets the member health check method. LB health checks can be registered and used across multiple LB server groups.

Component

A Load Balancer consists of a Load Balancer (Listener), LB server group (member), and LB health check.

Load Balancer

The components that make up a Load Balancer are as follows. By configuring each component, you can set up load balancing suitable for the customer’s workload.

LB server group

The elements that make up an LB server group are as follows. Traffic is delivered to members of the LB server group according to the settings of each component.

LB health check

The elements that make up the LB health check are as follows. Member health checks are performed according to the settings of each component.

Constraints

The Load Balancer of Samsung Cloud Platform has a default quota, which limits the number of Load Balancers, Listeners, LB server groups, and members that can be created. You can manage current usage through the Console and request additional quota for items that can be expanded.

Preliminary Service

This is a list of services that must be pre-configured before creating a Load Balancer service. Please refer to the guide provided for each service and prepare in advance.

1.1 - ServiceWatch metric

The Load Balancer sends metrics to ServiceWatch. The metrics provided by basic monitoring are data collected at 5‑minute intervals.

Basic Metrics

The following are the default metrics for the Load Balancer namespace.

The indicators whose names are displayed in bold text below are the key metrics selected from the basic metrics provided by Load Balancer. Key metrics are used to build the service dashboards that are automatically created for each service in ServiceWatch.

Each metric provides guidance in the user guide on which statistical values are meaningful when querying that metric, and among the meaningful statistics, the values shown in bold are the primary statistics. In the service dashboard, you can view key metrics using primary statistical values.

2 - How-to guides

Users can create a service by entering the required Load Balancer information and selecting detailed options through the Samsung Cloud Platform Console.

Create Load Balancer

You can create and use a Load Balancer service from the Samsung Cloud Platform Console.

To create a Load Balancer, follow these steps.

1. All Services > Networking > Load Balancer click the menu. 1. Go to the Load Balancer’s Service Home page.
2. Service Home on the page, click the Create Load Balancer button. 2. Go to the Load Balancer creation page.
3. On the Load Balancer creation page, enter the information required to create the service and select detailed options.
   • Enter or select the required information in the Service Information Input area.

• In the Additional Information Input area, enter or select the required information.

  Category	Required status	Detailed description
  Explanation	Select	Enter resource description
  tag	Select	Add tags Up to 50 tags can be added per resource

  Table. Load Balancer additional information input fields

4. Check the created service information and the estimated billing amount, and click the Create button.
   • Once creation is complete, check the created resources on the Load Balancer List page.
     Information

     • Load Balancer service does not provide access control for Service IP and service ports.
       
       • When creating a Load Balancer, select Use Firewall to manage communication between the client and the Load Balancer, and between the Load Balancer and members with firewall rules, and enable Save Firewall Logs to store access logs, which is recommended.
     • When creating a service and using the Firewall log storage feature, you must configure the log repository first. * If the log storage configuration is not completed, you cannot create a Load Balancer service.
     Caution

     If you use a firewall, you must add the rules required for Load Balancer communication. Register the rules, paying attention to the direction for each purpose.
     

     • If you do not add a rule, the Load Balancer service will not operate correctly.

     

     Purpose	Source IP	Destination IP	Protocol	Destination Port/Type	Direction
     Client → LB connection	Client IP	LB Service IP	Listener protocol	Listener service port	Outbound
     LB → Member connection	LB Source NAT IP	LB server group member IP	LB server group protocol	Member port	Inbound
     LB → Member health check	LB health check IP	LB server group member IP	Health check protocol	Health check port When the health check port and member port are different, register the member port	Inbound
