Auto Scaling​

What is Auto Scaling?

Businesses often experience fluctuations, and Auto Scaling helps you handle them. It launches instances only when you need them and stops them when they are no longer required. It automatically adds or removes ECS instances from your resource group in real time. A user-friendly interface also gives you the option to manually manage instances, policies, and scaling actions.

Why Should You Use Auto Scaling?

• Auto Scaling helps you reduce costs and stay focused on your business.
  
  • Auto Scaling works with ELB to balance the load among instances in your Auto Scaling group.
  • It maintains high application availability by adding instances based on demand and replacing unhealthy instances with new ones.
  • It supports scheduled, recurring, and alarm-based scaling policies to help you handle workload changes with confidence.
• Auto Scaling works together with your applications to provide a better user experience.
  
  • Lifecycle hooks allow your applications to respond to scaling events in your Auto Scaling group.
  • Graceful scale-in ensures that running tasks are completed before instances are stopped so that services are not disrupted.
  • Whenever an instance is launched or terminated in your Auto Scaling group, you will be notified.

Benefits of Using Auto Scaling for Your Business

• • Auto Scaling
    Auto Scaling automatically scales computing resources to ensure application availability through dynamic or scheduled scaling.

• • Load Balancing
    Auto Scaling automatically attaches instances in the Auto Scaling group to the load balancer so that traffic can be optimally distributed to all available instances.

• • Fault Tolerance
    Auto Scaling automatically checks the health status of ECS instances and replaces unhealthy instances with new ones to ensure service continuity.

• • Auto Notification
    Auto Scaling notifies you of any instance launch or termination in your Auto Scaling group.

• Dedicated Computing Cluster
  To physically isolate your ECS, submit a DCC request before creating ECS instances. After you obtain a DCC and assign a region to it, your ECS instances are automatically allocated to the DCC.
