Auto-scaling can assist you in optimising how your application is used, reducing waste, and lowering cloud costs. Although the learning curve is steep, auto-scaling has numerous benefits that can be enhanced with load balancing. If you are here to know How Does AWS Auto Scaling Work? And when to use it? Join FITA Academy for the best AWS Training In Chennai with a hands-on project for practical sessions to develop your skills technically.
What Is AWS Auto Scaling?
To reduce costs, AWS Auto Scaling can raise or decrease the capacity of AWS services. The service keeps track of all resources and scalable cloud services connected to the user’s apps.
These resources may include:
- Groups for Elastic Compute Cloud Auto Scaling
- Spot Fleets EC2
- Global secondary indexes and records for DynamoDB
However, using Amazon’s Elastic Compute Cloud (EC2) service is the most effective technique to comprehend auto-scaling. You can host your apps on cloud platforms, or compute instances, from EC2.
The Function of AWS Auto Scaling
In the case of EC2, AWS elastically scales your EC2 instances by starting new ones and stopping failing ones. When configuring a small number of instances with a specified set of scaling policies, you can use Amazon Auto Scaling.
Performance-based metrics delivered to CloudWatch are also used for auto-scaling. You could base performance measurements, for instance, on CPU limits.

The simplest form of auto-scaling operates in this manner. Elastic load balancing, however, makes it effective. Clients can, for instance, connect to the load balancer on Amazon, which then spreads them to your EC2 instances. The load balancer moves back to the next operational EC2 instance if an EC2 instance fails.
Setting up AWS Auto Scaling
There are two methods we can specify the behaviour of the launched instances when configuring EC2 Auto Scaling. Launch settings or launch templates are possibilities.
The benefits of AWS Auto Scaling are numerous. These consist of:
- Improved fault tolerance – You may watch your applications using AWS Auto Scaling.
- Improved cost management – Automatic scaling is accomplished using a set of threshold values. Depending on the needs of your company, you can scale up or down. You can do this to save money on staff and equipment. You may check all of your scaling charges from one convenient location due to it as well.
What Exactly Is an AWS Auto Scaling Group?
The scaling procedure is entirely dependent on AWS Auto Scaling Groups. By deploying launch configurations and/or templates for EC2, they control how events are scaled. They guarantee that a minimum and maximum number of instances are running and are scalable.
An Auto Scaling Group (ASG) is essentially a grouping of EC2 instances. As a result, the ASG’s size is determined by the capacity or number of instances that you have set up for the group.
How do auto scaling and load balancing interact?
Auto scaling cannot be replaced by load balancing. In fact, when the two cooperate, it can aid in efficient autoscaling. New instances are still needed to route connections, even while load balancing reroutes connections from unhealthy instances.
