Which service would you use to monitor cloud resources and track their usage?

The correct choice is Alibaba Cloud Cloud Monitor because it is specifically designed for monitoring cloud resources and tracking their usage. This service enables users to collect performance metrics, set up alerts, and visualize resource utilization across different Alibaba Cloud services. By leveraging Cloud Monitor, you can gain insights into how your resources are performing and assess whether they are being used efficiently, which is crucial for optimizing cloud workloads.

In contrast, Alibaba Cloud MaxCompute is primarily a data warehousing solution that focuses on large-scale data processing and analytics rather than monitoring or resource tracking. Alibaba Cloud ApsaraDB is a database service that provides managed database solutions for applications but does not specifically focus on monitoring resources. Alibaba Cloud Function Compute is a serverless computing service that allows you to run code in response to events and manage workloads without provisioning servers; however, it also does not serve the primary purpose of monitoring and tracking resources.
