Scenario

Your infrastructure has two application endpoints that need different monitoring strategies via Route 53 health checks.

Task

Note: You can use either the AWS Management Console or AWS CLI to complete this task.

Step 1: Create the web-server health check

WEB_HC=$(aws route53 create-health-check \
  --caller-reference "web-server-$(date +%s)" \
  --health-check-config '{
    "IPAddress": "10.0.1.10",
    "Port": 80,
    "Type": "HTTP",
    "ResourcePath": "/health",
    "FailureThreshold": 3,
    "RequestInterval": 30
  }' --query 'HealthCheck.Id' --output text)

Creates a standard HTTP health check that monitors port 80 at /health every 30 seconds, marking unhealthy after 3 consecutive failures.

Step 2: Name the web-server health check

aws route53 change-tags-for-resource \
  --resource-type healthcheck \
  --resource-id "$WEB_HC" \
  --add-tags Key=Name,Value=web-server

Health check names are stored as tags, not as a direct property.

Step 3: Create the api-server health check

API_HC=$(aws route53 create-health-check \
  --caller-reference "api-server-$(date +%s)" \
  --health-check-config '{
    "IPAddress": "10.0.2.10",
    "Port": 443,
    "Type": "HTTPS",
    "FailureThreshold": 5,
    "RequestInterval": 10,
    "Inverted": true,
    "Regions": ["us-east-1", "eu-west-1", "ap-southeast-1"]
  }' --query 'HealthCheck.Id' --output text)

Creates an HTTPS health check with fast 10-second interval, inverted status (reports healthy when endpoint is down), and monitors from only 3 specific regions.

Step 4: Name the api-server health check

aws route53 change-tags-for-resource \
  --resource-type healthcheck \
  --resource-id "$API_HC" \
  --add-tags Key=Name,Value=api-server

Step 5: Verify both health checks

aws route53 list-health-checks --query 'HealthChecks[].{Id:Id, IP:HealthCheckConfig.IPAddress, Type:HealthCheckConfig.Type, Port:HealthCheckConfig.Port, Threshold:HealthCheckConfig.FailureThreshold, Interval:HealthCheckConfig.RequestInterval, Inverted:HealthCheckConfig.Inverted}'

Lists all health checks with their configuration to confirm both are set up correctly.
