AWS Auto-scaling Block Diagram

To create the Auto Scaling Scenario we will have complete the following steps :

1. Create a VPC having two subnets (Public & Private).

2. Creating the Internet gateway & associate with with the VPC just created.

3. Create the routing gateway tables to assign the subnet associations & assign it to the subnets to pass the route of "Internet Gateway" to "0.0.0.0/0" to access internet.

4. Create the AWS AutoScaling Group , Target Group & the ALB (Internet Facing)

5. Create a security group to allow connections over the instances & set the Minimum desired capacity "2" & max desired capacity to "3" in the Autoscaling group to resource bind AWS
