An ALB target group for an ECS civic app should not receive traffic until DB connections are warmed and feature flags are loaded. What should they configure?
Select an answer to reveal the explanation.
Short Explanation
Listening on a port is not the same as ready. Point the ALB health check at a readiness probe that waits for warm DB pools and loaded feature flags.
Full Explanation
Load balancer health checks should reflect application readiness—warmed database connections and loaded feature flags—before traffic is accepted. A PID-only or always-200 check admits unready tasks; removing checks or using Cost Explorer anomalies does not gate readiness correctly.
