问题
We are using ECS Farget container service for our ruby on rails containers. We have implemented NLB with HTTP health checks in the target group but as we know that "NLB Target Group health checks are out of control". This is consuming our CPU of each container up to 8% so we are thinking of to migrate HTTP HealthChecks to TCP HealthChecks. Can anyone comment on how TCP HealthCheck works??? Does it only connects to port for a health check or it's actually hit the API?
