Comprehensive Guide to AWS Monitoring, Scaling, and Traffic Management

AWS offers CloudWatch for centralized monitoring, providing metrics, visualizations, and alarms triggering automated actions. EventBridge facilitates event-driven architectures, integrating with numerous AWS services. Cost management is addressed through AWS Cost Explorer, Budgets, and the Cost and Usage Report. Auto Scaling, with its various strategies (scheduled, dynamic, predictive), ensures application availability across EC2, ECS, and other services. Database scaling options include vertical and horizontal scaling for Aurora and RDS, along with DynamoDB's on-demand and auto-scaling models. Elastic Load Balancing (ELB) distributes traffic across availability zones using Application, Network, and Gateway Load Balancers. Amazon Route 53 manages DNS, offering advanced routing policies for optimized traffic management and disaster recovery. Best practices emphasize comprehensive monitoring, strategic scaling, appropriate load balancing, and effective DNS management. Combined use of these services optimizes cloud architecture for high availability, scalability, and cost efficiency.
