Hey Jeff, This functionality is not currently available in Open Source or Enterprise Scalr. As of today only the Sequential and Simultaneous launch options are available. Keep in mind that even if configured for Sequential launch Scalr is only able to place the API call with your Cloud Provider for handling and it is possible that your observed launch order may in some cases differ from what you have defined in the Farm Designer. Typically this is par for the course in the Cloud as failures may occur at any time, and the right solution here is to alter the way of thinking about application architecture so that you account for the typical types of failures that can and will occur for cloud resources. (Ref. Pets vs. Cattle ideology) Ideally your application and the Orchestration logic you implement will allow for dynamic (re)configuration of your nodes and services to maintain operability, regardless of the order launched or unexpected scale in/out events. If this is a hard requirement for your use case you may be able to work around this by using custom scaling metrics or our API to increase autoscaling minimum from 0 to your desired count for each subsequent Farm Role in sequence after the successful simultaneous launch of your first Farm Role, but of course this will require quite a bit of logic design on your end to achieve your desired results. Having said that, we are always looking for feedback and new use cases from our users so that we can ensure Scalr meets our customer's needs as efficiently as possible. If you do have a use case where this functionality would be a hard requirement, could you please provide any details you may be able to share about such a use case?
Many thanks, Wm.
