Auto Scaling

Auto Scaling enables you to automatically increase or decrease the number of running Amazon EC2 instances in response to your web application’s usage and the configuration you define. Auto Scaling makes it easy for you to optimize your Amazon EC2 usage, automatically scaling your cluster to ensure your application has the right number of instances running to meet your workload demands. Auto Scaling is particularly well suited for applications that experience hourly, daily, or weekly variability in usage.

Elastic Load Balancing

Elastic Load Balancing offers the ability to evenly spread requests across your running Amazon EC2 instances. Unlike traditional load balancers or load balancing software, there is no need to provision, manage, or plan for load balancing capacity needs. Each Elastic Load Balancer is automatically scaled, fully fault-tolerant, and distributes incoming application traffic across a group of Amazon EC2 instances.

Amazon CloudWatch makes it easy to monitor your Amazon EC2 instances and aggregate metrics from instances like CPU or disk utilization over different time ranges and across different pools of resources. This service is tightly integrated with Amazon EC2's Auto Scaling and Elastic Load Balancing, enabling you to use monitoring metrics to trigger scaling activities.
