Amazon CloudWatch provides AWS customers the monitoring platform for keeping tabs on their cloud infrastructure and applications. In this session, we show you how to use CloudWatch to monitor vital operational resource data such as EC2 Instance CPU Utilization, ELB Request Counts, RDS Read Throughput and much more. Learn how to configure CloudWatch Alarms to alert you any time services are operating outside of ranges you define. Finally, see how you can monitor applications on your EC2 instances or outside of AWS.
