Which service on Alibaba Cloud is responsible for real-time monitoring and alerting?

Alibaba Cloud CloudMonitor is the service specifically designed for real-time monitoring and alerting within the Alibaba Cloud ecosystem. It provides comprehensive monitoring capabilities that allow users to track the performance and health of their cloud resources and applications in real time.

With CloudMonitor, users can set up alert configurations based on specific metrics and thresholds. This enables proactive management of applications and services by notifying teams of any anomalies or performance issues as they arise. The ability to receive alerts through various channels ensures that necessary actions can be taken quickly to mitigate potential problems.

In contrast, the other services mentioned serve different purposes. Alibaba Cloud Data Lake Analytics focuses on data analysis and processing capabilities rather than monitoring. Alibaba Cloud Application Monitor is more oriented towards application-level details and performance insights but does not encompass the broad scope of monitoring that CloudMonitor provides. Alibaba Cloud API Gateway is used for managing and securing API calls, but it does not offer the monitoring and alerting functionalities that are critical for performance oversight.

Therefore, CloudMonitor stands out as the essential tool for ensuring observability and operational efficiency in real time on Alibaba Cloud.
