Maximization of network
efficiency through the automatic distribution of traffic

Load balancer

01

This feature automatically distributes inbound traffic to prevent traffic bottlenecks and to ensure efficient network operation.

  • Single Zone LB
    - This is a load balancer for distributing traffic within a single zone.
    - You can register two or more instances belonging to the zone in question as load balancing members.
  • Multi-Zone LB
    - This is a load balancer for distributing traffic between two or more zones within a multi-zone.
    - It provides DNS-based GSLB service, and a load balancer is created and operated in each zone.
    - Load balancing members can be registered in other zones using the cross-zone network.

  • Can select the protocol and distribution method according to your needs

    • Types of Supported Protocols
    - TCP, HTTP, HTTPS

    • Distribution Methods
    - Round robin, a way of directing the same amount of requests to the designated servers sequentially
    - Source IP, a way of directing a specific IP request to a specific server
    - Least connection, a way of direct the request to the server receiving the least requests

  • L7 Features available

    - When creating a load balancer, if you select an application load balancer, you can configure L7 rules to refine distribution.
    - L7 policies only work properly when the listener's protocol is HTTP/TERMINATED_HTTPS.
