AWS Application Auto Scaling

• It is a service which role is to monitor our apps and automatically adjust capacity to maintain steady and predictable performance at lowest cost
• From a single place we can manage auto scaling of multiple resources across multiple services
• We point to our app and select the services and resources we want to scale (no need to setup alarms and scaling actions for each service)
• To search for resources/services we can use CloudFormation Stacks, Tags or EC2 Auto Scaling Groups
• We build Scaling Plans to automatically add/remove capacity from our resources in real-time as demand changes
• Supports Target Tracking, Step and Scheduled Scaling Policies
