Auto Scaling
(AS)
Auto Scaling automatically adjusts compute resources based on scaling policies,
striking a balance between performance and cost.
Why Auto Scaling?
Auto Scaling automatically adjusts computing resources based on user service requirements and configured AS policies.
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 groups.
- It maintains high application availability by adding instances on demand and replacing unhealthy instances with new ones.
- It supports scheduled, periodic, and alarm scaling policies to help you confidently handle with any changes in workload.
Auto Scaling works together with your applications for a better user experience.
- Lifecycle hooks allow your applications to respond to scaling events in your Auto Scaling groups.
- Graceful scale-in ensures that running tasks are complete before the instances terminate so services are not interrupted.
- Any time an instance is launched or terminated in your Auto Scaling groups, you will be notified.

Pay Only for What You Need
Launching instances only when you need them, and terminating them when you don't, means that costs remain as low as possible while ensuring that resources are available whenever you need them.
Be Prepared for Any Situation
Businesses often go through ebbs and flows, and Auto Scaling handles it all. By automatically adding or removing ECS instances from your resource groups in real time, based on scheduled, periodic, or alarm policies, Auto Scaling molds itself to fit your needs.
Benefit from Intuitive Scaling
Automatic resource scaling reduces your workload and adds or removes instances as required. A user-friendly interface also gives you the option to manually handle scaling instances, policies, and actions.
Anticipate Issues Before They Arise
Auto Scaling instinctively monitors key metrics and alerts you when something changes, leaving you time to respond accordingly. It also automatically detects and replaces any unhealthy instances with new ones to ensure that your applications never crash.
