Metrics are defined as quantifiable measurements that provide insights into the performance of cloud resources and applications. In the context of cloud computing, metrics can encompass a variety of indicators, such as CPU usage, memory consumption, disk I/O, and network throughput. These metrics allow administrators and developers to monitor the health and efficiency of their applications and infrastructure, enabling them to make informed decisions based on real-time data.

By analyzing metrics, organizations can identify trends, diagnose issues, and optimize performance. This capability is crucial for maintaining service levels and ensuring that resources are being utilized effectively. Continuous monitoring of metrics can help in scaling resources appropriately and improving overall application reliability.

In contrast, templates typically refer to predefined configurations used to create resources in a consistent manner, while a stack often refers to a collection of related resources managed together, particularly in the context of services like AWS CloudFormation. Units, although they can pertain to measurements, do not encapsulate the broader concept of performance indicators in the same way that metrics do. Thus, metrics serve as the essential term for indicating the performance of cloud resources and applications.
