Create and Configure the Auto Scaling Group in EC2
Auto Scaling is an Amazon Web Service that allows instances to scale when traffic or CPU load increases. Auto-scaling is a service that monitors all instances that are configured into the Auto-Scaling group and ensures that loads are balanced in all instances. Depending on the load scaling group, increase the instance according to the configuration. When we created the auto-scaling group, we configured the Desired capacity, Minimum capacity, maximum capacity, and CPU utilization. If CPU utilization increases by 60% in all instances, one more instance is created, and if CPU utilization decreases by 30% in all instances, one instance is terminated. These are totally up to us; what is our requirement? If any Instance fails due to any reason, then the Scaling group maintains the Desired capacity and starts another instance.
The auto-scaling group follows Horizontal Scaling. This service is very important for us nowadays because we do not need to create new instances manually and do not require manual monitoring.
AWS auto-scaling is used to scale up and scale down the EC2 instance depending on the incoming traffic. You can scale up and scale down the applications in a few minutes based on the traffic which will decrease the latency of the application to the end-users. You can integrate the AWS Auto Scaling with multiple services provided by AWS like Amazon traffic, Amazon DynamoDB, and Amazon Aurora. You can also decrease the cost of an application because of dynamic scaling. When there is traffic, only maximum resources are used other it will use minimum resources.
- Dynamical scaling: AWS auto-scaling service doesn’t require any type of manual intervention it will automatically scale the application down and up depending on the incoming traffic.
- Pay For You Use: Because of auto-scaling the resource will be utilized in the optimized way where the demand is low the resource utilization will be low and if the demand is high the resource utilization will increase so the AWS is going to charge you only for the number of resources you really used.
- Automatic Performance Maintenance: AWS autoscaling maintains the optimal application performance while considering the workloads it will ensure that the application is running to the desired level which will decrease the latency and also the capacity will be increased by based on your application
How AWS Auto Scaling Works?
AWS autoscaling will scale the application based on the load of the application. Instead of scaling manually AWS auto scaling will scale the application automatically when the incoming traffic is high it will scale up the application and when the traffic is low it will scale down the application.
First, you should choose which service or an application you want to scale then select the optimization way like cost and performance and then keep track of how the scaling is working.

FAQs On Create And Configure The Auto Scaling Group In EC2
1. What Is The Difference Between EC2 Auto Scaling And AWS Auto Scaling?
AWS Auto-scaling is used to scale the AWS EC2 instance for better availability and productivity
2. Why Do We Need Auto Scaling?
Auto scaling is essential to efficiently manage resources in response to varying workloads. It optimizes costs, ensures performance, and maintains availability by automatically adjusting resources up or down based on demand.
