Description
closes #1012
IRIS ECS service에 autocaling 기능을 추가했습니다.
Cloudwatch에 Alert 설정을 해 놓고,
특정 alert가 trigger되는 경우에 scale-in/out 되도록 설정했습니다.
Additional context
API ECS Cluster 에 AutoScaling이 필요한가? 에 대해서 이야기해보는 것이 좋을 것 같아요!
물론 본격적으로 Load Test를 해봐야 알겠지만, 예전에 했던 LoadTest 결과를 보니깐 Client API 서버에는 CPUUtilization이 10%를 넘기질 않더라구요.
=> EC2 Auto Scaling은 설정이 되어있지만 Service Auto Scaling이 적용되지 않아서 정상적으로 작동되는 상태는 아니긴 합니다.
