AWS CloudWatch

AWS CloudWatch is a monitoring and observability service provided by Amazon Web Services. It enables you to collect and track metrics, logs, and events from your AWS resources and applications running on AWS.\n\nCloudWatch provides real-time monitoring of AWS resources such as EC2 instances, RDS databases, Lambda functions, and more. It collects and processes raw data into readable, near real-time metrics.\n\nKey capabilities include:\n\n1. Metrics monitoring: Track performance data like CPU utilization, network throughput, and storage usage.\n\n2. Alarms: Set thresholds and receive notifications when metrics exceed those thresholds.\n\n3. Dashboards: Create visual displays of your metrics and alarms for easy monitoring.\n\n4. Logs: Collect, monitor, analyze, and store log files from applications and AWS services.\n\n5. Events: Respond to changes in AWS resources by triggering actions using CloudWatch Events (now part of EventBridge).\n\n6. Application Insights: Automatically detect and diagnose issues in applications.\n\nCloudWatch integrates with other AWS services like SNS for notifications, EC2 Auto Scaling for dynamic resource adjustment, and AWS Lambda for automated remediation.\n\nUsing CloudWatch, you can gain operational visibility, troubleshoot issues, optimize resource utilization, and ensure application health. Standard metrics are available at 5-minute intervals by default, while detailed monitoring provides 1-minute intervals for an additional cost.\n\nWith CloudWatch Logs Insights, you can perform interactive queries on your log data. CloudWatch also offers Container Insights for monitoring containerized applications and services.\n\nIn the context of the AWS Solutions Architect exam, understanding CloudWatch is essential for designing resilient, self-healing, and well-monitored architectures.
