AWS Technical Essentials Practice

The components like alarms and metrics in AWS CloudWatch are specifically designed for monitoring applications and resources within the AWS cloud environment. Metrics provide a quantitative measure of performance, enabling you to track how well your applications and resources are functioning. For instance, metrics can show CPU utilization, memory usage, and network traffic, which can be crucial for understanding the health and performance of your systems.

Alarms complement these metrics by allowing you to set thresholds, which trigger notifications when a certain metric reaches an undesirable level. This feature helps in proactive management, as it can alert you to potential issues before they impact application performance or availability. By using these tools, you can ensure that your applications and resources are operating efficiently and can respond swiftly to any emerging problems.

In contrast to the other choices, components like alarms and metrics do not play a role in accessing, using, or providing applications and resources; their sole purpose is centered around the monitoring process.
