What is the function of the Cloud Monitor service?

The Cloud Monitor service is designed primarily to provide monitoring and alerting capabilities for various resources and services within Alibaba Cloud. It ensures that users can keep track of their cloud infrastructure's performance, availability, and health. By monitoring resource metrics like CPU usage, memory consumption, and network traffic, Cloud Monitor helps users detect and respond to operational issues more efficiently.

Additionally, it offers alerting features that notify users in real time when specific thresholds are breached, allowing for swift actions to maintain optimal service performance. Given its essential function in maintaining visibility over cloud resources, Cloud Monitor plays a crucial role in the overall management of cloud environments, helping enhance reliability and operational efficiency.

The other options focus on different aspects of cloud services. Automating resource scaling relates to a specific functionality of application performance management rather than general monitoring. Data encryption concerns security and privacy, which is a distinct service from monitoring. User access management pertains to identity and access management services, addressing security in access rights instead of performance monitoring.
