Overview

Service Overview

GSLB (Global Server Load Balancing) automatically distributes network traffic to an available adjacent region based on DNS when traffic increases in a specific global region. In the event of a failure on a specific server, the service can continue stably by load balancing network traffic to available new resources.

Features

• Stable Service Provision: Through the health check function, which checks the normal operation of connected resources, if a failure occurs in a specific server, the corresponding resource is immediately failed over and removed from the domain response, thereby diverting traffic to other resources to provide stable services.
• Service Port Easy Setup: You can easily create and manage GSLB and set up/service ports through the web-based console. For L4 unit load balancing, multiple port settings are possible (e.g., 80, 443, 8080-8090), and you can apply and manage multiple load balancing rules simultaneously.
• Efficient Cost Management: The cost is determined by the number of configured domains, the number of added Health Check resources, and the number of queries, so the billing method is applied in a granular manner, allowing for efficient cost management.

Provided Features

GSLB service provides the following features.

• GSLB Creation/Management: You can register multiple resources to a single GSLB.
• Distributed Algorithm Selection: Provides Ratio method, which distributes traffic in proportion to the weight of the connection target, and Round Robin method, which distributes traffic evenly in a circular manner.
• Health Check 설정: You can set the check cycle (Interval), service down detection time (Timeout), response wait time (Probe Timeout), protocol (ICMP, TCP, HTTP, HTTPS), and service port.
