Provides reference architecture and CloudFormation templates to power ECS using a mix of spot instances and ondemand instances with independent autoscaling
Thank you very much for providing this reference architecture!
I would like to ask question re use of instance-purchase-option placement strategy.
In current setup you have 2 distinct clusters and 2 services that deployed in to different clusters:
on-demand
spot
As you always deploying spot service in to spot cluster and you always deploying on-demand service in to on-demand cluster why do you use instance-purchase-option placement strategy?
I understand that it would make sense to use it in case of one cluster that has on-demand and spot instances mixed together but when you have 2 separate clusters .... Am I missing something? :)
