Explain Use Cases for AWS CloudWatch.

Infrastructure Monitoring
- Monitor EC2 instances, RDS databases, Lambda functions, S3 buckets, and other AWS resources for performance, health, and resource utilization.
Application Performance Monitoring (APM)
- Track the performance of your web applications, microservices, and APIs. Monitor response times, error rates, and throughput.
Automated Remediation
- Set alarms to automatically take corrective actions when a resource exceeds a threshold (e.g., scaling an EC2 instance when CPU usage is high).
Cost Management
- Monitor AWS service usage and set alarms to track cost-related metrics, ensuring that you stay within budget.
Log Aggregation and Analysis
- Collect logs from EC2 instances, Lambda functions, VPC flow logs, and other sources, and analyze them for operational insights or troubleshooting.
