Amazon CloudWatch - Monitoring and Observability
Amazon CloudWatch is a monitoring and observability service that provides data and actionable insights to monitor applications, respond to performance changes, and optimize resource usage.
Main components:
- Metrics: Numerical data about resources (CPU, memory, network)
- Alarms: Notifications when metrics exceed thresholds
- Logs: Collection and analysis of log files
- Dashboards: Customized metric visualization
Use cases:
- Monitor application performance
- Detect anomalies and issues
- Automate responses to events
- Optimize costs through usage analysis

Elastic Load Balancing and Auto Scaling
Elastic Load Balancing (ELB):
Automatically distributes incoming application traffic across multiple targets in one or more Availability Zones.
Benefits:
- High availability
- Automatic detection of unhealthy instances
- Automatic capacity scaling
Auto Scaling:
Automatically adjusts capacity to maintain steady, predictable performance at the lowest possible cost.
Advantages:
- Better fault tolerance
- Greater availability
- Better cost management
- Automatic response to demand changes
