클러스터를 어떻게 구성했는지 알려주세요~ (마스터 노드 : n 대, 워커 노드 n대)
- 마스터노드 1대, 워커노드 2대로 구성했습니다.
- 마스터 노드의 경우에는 적어도 3대 까지는 두는게 맞다고 생각하지만, 단순 과제용 이기 때문에 한대만으로 충분하다고 생각해 1대만 두었습니다.
- 워커노드의 경우에는 스트레스 테스트를 해가면서 점차적으로 늘렸는데 2대 까지만으로도 충분하다고 생각하여 2대로 구성했습니다.
스트레스 테스트 결과를 공유해주세요 (기존에 container 한대 운영시 한계점도 같이 공유해주세요)
- 변경된 점이 많아 단순 비교를 하기를 힘듭니다.
- 변경된 점
- 컨테이너 환경에서는 테스트를 local에서 진행 -> 쿠버네티스로 구성한 이후 원격에서 호출 (네트워크 전송 시간 추가)
- 레디스의 경우 앱과 같은 서버에서 띄워 local 간 통신 -> 쿠버네티스로 구성한 이후로는 DB서버에 레디스를 구성했습니다. (네트워크 전송 시간 추가)
- 이러한 점 때문에 동접자수 2000명으로 테스트할 경우 응답이 지나치게 낮아 동접자수 1000명 부터 다시 테스트 했습니다.
- 따라서 이전과 단순 비교는 힘들지만 테스트 결과는 아래와 같습니다.
컨테이너 환경, 로컬 레디스, 동접자 2000

결과
- 워커 노드 1대에 레플리카 5, 10인 경우에 비하면 워커 노드 2대의 경우 높은 성능을 보여줬음
- 워커 노드 3대 까지 테스트 하는 것은 낭비라 생각하여 여기서 테스트 종료
현재 워커노드에서 몇대의 컨테이너를 운영중인지 공유해주세요
현재는 2대의 워커노드에 총 10개의 컨테이너를 운영중입니다. 참고로 1대의 워커노드에 10개의 컨테이너를 운영했을 경우 자원을 지나치게 나눠 가져(추측) 오히려 1대의 워커노드에 5개의 컨테이너를 구성했을때 보다 성능이 좋지 않았습니다.
