How AWS CloudWatch Works?

Data Collection
- CloudWatch collects data in the form of metrics, logs, and events from your AWS resources and applications.
- For example, EC2 instances send metrics like CPU usage, disk reads/writes, network traffic, and status checks to CloudWatch automatically.
Data Storage
- The collected data is stored in CloudWatch for analysis and historical performance tracking.
Data Visualization
- CloudWatch provides dashboards and visualizations that help you monitor the health of your AWS environment and identify potential issues.
Alarms and Automation
- Based on the collected data, CloudWatch allows you to configure alarms to notify you when certain thresholds are reached.
- You can set actions based on these alarms, such as triggering Auto Scaling, invoking AWS Lambda functions, or sending alerts to an email or SNS topic.
