Amazon AutoScaling Scale in removes instance like FIFO manner

Question

Currently I am using amazon auto scaling service. I have observed that when there is scale in it removes firstly created instance. My problem is I also want to put RabbitMQ in auto scaling, and if i configure first instance as master instance then when there is scale in it removes master rabbitmq instance. I want to know that is there any way to give pattern of scale in for removing instance on Amazon EC2 auto scaling policy?

You probably want to leave your master RabbitMQ instance out of the auto-scaling cluster. and launch a secondary instance and have that auto-scale.... Remember to add both the Master Instance and the auto-scaling cluster to the load-balancer.
