Function

1. Multi port

로드밸런서는 특정 서버에 트래픽이 집중되는 것을 없애기 위해 전용장비(VPX로드밸런서)를 이용하여 각 개별서버로 부하를 분산함으로써, 네트워크 효율성을 증대할 수 있는 서비스입니다.

Load balancer allows multiple service ports (example: 80, 443) to exist on a single VIP (LB IP) by having subsequent load balancers use the same IP but different Ports.

Cost ratios compared to flat rate

- Comparison with flat-rate using full traffic

Mbps Flat rate Meter rate Ratio to flat rate
100 240,000 208,800 87%
300 650,000 597,600 92%
500 1,000,000 986,400 99%

* Actual usage is usually less than 15%, where meter rate is significantly more cost-efficient.
