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.

    * The multi-zone LB is provided to the R zone with priority.

How to Use

1. Create a pool with the protocol and distribution method of the load balancer settings configured.
2. Create a VIP (virtual IP address) connected to a public IP address.
3. Register VMs to distribute the load according to the pool settings with the LB members.
4. Set the monitoring value for load balancer management.
5. Connect the VIP to the public IP address where the load balancer will be used, and the traffic coming into the public IP address in question will be distributed.
