EC2 Autoscaling ​

Amazon EC2 Auto Scaling helps you maintain application availability and allows you to automatically add or remove EC2 instances according to conditions you define. You can use the fleet management features of EC2 Auto Scaling to maintain the health and availability of your fleet. You can also use the dynamic and predictive scaling features of EC2 Auto Scaling to add or remove EC2 instances. Dynamic scaling responds to changing demand and predictive scaling automatically schedules the right number of EC2 instances based on predicted demand. Dynamic scaling and predictive scaling can be used together to scale faster.

Auto Scaling is an excellent deployment option with EC2 instances (among other AWS service choices). It permits you to:

• Maintain application availability.
• Scale your Amazon EC2 capacity automatically according to conditions that you define.
• Set the exact number of EC2 instances you want running at any given time.
