CloudWatch Use Cases
- Control applications logs. We can track logs from various applications in the CloudWatch console.
- Monitor AWS instances resources and optimize them. Using CloudWatch, we can get information about the health and performance of running AWS resources. And based on this, we can draw a conclusion about the use of resources (increase or decrease the use of resources).
- Troubleshoot the AWS infrastructure. We can track and send alerts to the SNS topic based on logs or metrics. And also, if necessary, configure Autoscaling based on the metrics of our instance.

New unified CloudWatch can collect both logs and metrics from EC2 instances. The older CloudWatch Logs agent is on the path to deprecation.
