AWS CloudWatch
AWS CloudWatch is a monitoring and observability service provided by Amazon Web Services (AWS) for cloud resources and applications. It collects and tracks metrics, monitors log files, sets alarms, and automatically reacts to changes in AWS resources. It provides a unified view of operational health and performance across AWS infrastructure, applications, and services.
Developers should use AWS CloudWatch when deploying applications on AWS to gain visibility into system performance, troubleshoot issues, and ensure reliability. It is essential for monitoring AWS services like EC2, Lambda, and RDS, setting up automated responses to events, and analyzing logs for debugging and compliance purposes. Use cases include tracking application latency, monitoring resource utilization, and triggering auto-scaling actions based on metrics.
