Apple DevOps Engineer System Design Questions

Apple's cloud services require constant monitoring to ensure uptime and performance. This service needs to track various health metrics and alert the relevant teams about issues.
Problem statement: You are required to design a ServiceHealthMonitor class that can check the status of services, log metrics, and send alerts if health checks fail.Class Method Signatures:
- check_status(service_name: str) -> str: Returns the status of the specified service.
- log_metric(service_name: str, metric_value: float) -> None: Logs specified metrics.
- alert_if_needed(service_name: str) -> None: Sends an alert if the service status is critical.Example 1:
Input: Service name 'iCloud', metric value 0.2.
Output: Status 'Healthy'.
Explanation: The system checks the service status based on the metric and ensures proper alerting.Constraints:
- The service metrics are represented as floating-point numbers between 0.0 (critical) to 1.0 (healthy).
- Services can be checked concurrently, requiring efficient state management.
