Monitoring vs. Audit (with AWS Services & Key Metrics)

1. Monitoring

Definition: Monitoring is the real-time tracking of system health, performance, and security to detect issues and optimize operations.

Purpose:
- Ensure availability and performance of applications and infrastructure.
- Detect failures or performance bottlenecks.
- Provide insights for auto-scaling and optimization.

AWS Services for Monitoring:
- Amazon CloudWatch – Collects metrics, logs, and sets alerts.
- AWS X-Ray – Traces application requests to detect latency issues.
- Amazon CloudWatch Logs – Stores and analyzes log data.


2. Audit

Definition: Auditing is the periodic review of logs, configurations, and access history to ensure compliance, security, and accountability.

Purpose:
- Maintain compliance with industry regulations (e.g., GDPR, HIPAA).
- Track changes in AWS resources.
- Investigate security incidents and unauthorized access.

AWS Services for Audit:
- AWS CloudTrail – Logs all API actions in AWS for security analysis.
- AWS Config – Monitors changes in AWS resources and ensures compliance.
- Amazon GuardDuty – Uses AI to detect security threats.
