On EC2 let us install Wordpress application
Now let's take AMI of EC2 Instance (AMI is input for autoscaling's launch configuration) > create
Go to certificate manager > register your domain name(for security)
Go to AMIs to check if AMIs are created or not
Go to autoscaling > Launch Configurations (make sure to select same security group)>
configure auto-scaling through launch configurations>
create autoscaling group > select group size as the minimum amount of ec2s launched> make sure to select right vpc> add multiple subnets where you want these instances to be launched in our case these are public subnets add all those > on advanced settings attach your classic load balancer with the auto-scaling configuration
on creating ASG I selected '

you can add notification to the SNS that you have configured> configure and create an auto-scaling group
Once you are done go to ELB > ELB's instances section > look for the status you the instances
