# percentage of on demand instances to use after the on demand base capacity has been met [0, 100] (default: 50)

# max price for spot instances (default: the on-demand price of the primary instance type)
# number of spot instance pools across which to allocate spot instances [1, 20] (default: number of instances in instance distribution)
