Load balancer functions that enhance high availability and fault tolerance

In this service, IDC Frontier manages operations on behalf of customers, from the installation and configuration of load balancers that carry out decentralized control of access loads to respective servers to monitoring and troubleshooting.


No worries about traffic concentration

Large amounts of access are distributed to multiple servers to balance the loads so that the website can be operated stably.

Reduction of operation costs

All operations and management can be outsourced to our company, so the total costs of ownership can be reduced including system administrator workloads and management costs.

Improved availability and fault tolerance

Redundant configurations allow the service to be continued in the event of a failure.

Provision of the SSL acceleration function as standard

By centralizing data encryption and decryption processing using SSL in a load balancer, we can protect our customers' servers from overload and achieve a significant increase in processing speed.

Real-time reporting - Service operation information - (dedicated appliance type only)

The dedicated appliance type allows users to view graphic charts such as a traffic status chart on a dedicated customer site "Customer Portal".

  • Port traffic (bps)
  • Port traffic (pps)
  • CPU utilization (%)
  • Memory utilization (%)
  • Number of real server sessions (sessions/sec)
  • Number of virtual server sessions (sessions/sec)

SLA (dedicated appliance type only)

The dedicated appliance type is applicable to the Service Level Agreement (SLA) for restoration time.

SLA guaranteed values (dedicated appliance type only)

Managed Load Balancing applies SLA (Service Level Agreement), which can be proof of high quality.

Quality assurance related to equipment failures (*1)

Software failure etc. other than hardware Recovery within 4 hours after submitting a trouble ticket (*2)
Hardware failure Recovery within 10 hours after submitting a trouble ticket (*2)

*1 It refers to cases where the equipment under this Service Agreement has become completely unusable (Severity 1). *2 When the system designated by our company has received failure information.

Quality assurance

Reduction criteria

In case of falling below the above SLA guaranteed values, we will reduce the monthly fee by 15%. However, the SLA can only be applied once a month. (*3)

*3 Customers can receive a reduction once within 24 hours after submitting a trouble ticket. Even if more than one failure occurs within this period, you cannot receive reduction more than once.

How to make a claim for reduction

To apply for reduction, the customer is required to fill out a reduction application form and submit it within 14 days after the occurrence of the failure. The reduction process is usually implemented at the time of billing for the next month, but it may be implemented in the following month or later depending on the occurrence timing of the failure and the status of the contract.


Reduction is not applied to the following cases.

  • Incidents related to the introduction of the service
  • Maintenance (including emergency maintenance)
  • Failure of the network system managed by the customer
  • Cases due to external attacks, interference, etc.
  • Other cases due to force majeure
