💡 Definition

CloudWatch Dashboards are customizable home pages in the CloudWatch console that you can use to monitor your resources in a single view, even across different Regions.

🔑 Key Concepts

Customizable: You create the layout using widgets (line charts, numbers, text).
Multi-Region: Can display metrics from multiple Regions on a single dashboard.
Sharing: Can be shared with people who don't have AWS accounts.

⚙️ How it Works

You create a dashboard and add widgets. Each widget displays a specific metric or set of metrics (e.g., "EC2 CPU across all web servers").

🎯 Use Cases

NOC (Network Operations Center): A big screen showing system health.
Application View: Combining DB, Web, and Cache metrics in one place to see full stack health.

💰 Pricing Model

Free Tier: 3 dashboards (up to 50 metrics).
Paid: Charged per dashboard per month.
