Is it possible add cluster on autoscale?

can i add aerospike cluster under aws autoscale? Like . my initial autoscale group size will 3, if more traffic comes in and if cpu utilization is greater then 80% then it will add another instance into the cluster. do you think it is possible? and does it has any disadvantage or will create any problem in cluster?

Since this was also asked on StackOverflow I’m linking to my answer there: amazon web services - add node to existing aerospike cluster using autoscale - Stack Overflow
