1. VPC peering 을 사용할 경우, Splunk O11ly Cloud 가 Seoul region에 없는 상황에서 private connectivity 사용이 가능
[고객 사례]
고객의 AWS region: ap-northeast-2 (Seoul)
Splunk Observability Cloud realm: jp0 (ap-northeast-1: Tokyo)

위 예처럼, VPC peering을 활용시, 동일한 AWS region이 아닐 경우에도 private connectivity 기능을 사용할 수 있음.
인터넷 망을 통하지 않기 때문에, security connect
네트워크 비용 측면에서 유리

2. 비용적인 장점
Private Link를 사용하지 않을 경우,
서울 리즌의 NAT gateway 비용: $0.059 / GB

Private Link 비용
Tokyo 리즌의 Private Link 비용: $0.014 / GB
VPC Peering is free
결론
AWS price list 기준으로 74.3% 데이터 비용 감소 효과가 있음.
