# AZURE KAMAJI NODE POOL EXAMPLE
# =============================================================================
#
# This example demonstrates multi-pool Azure node configuration with both
# manual and automatic scaling options:
#
# SCALING MODES:
# - enable_autoscaling = true:  Azure manages scaling based on CPU metrics
# - enable_autoscaling = false: Terraform directly controls pool_size
#
# For manual control, set enable_autoscaling = false and adjust pool_size
# in your configuration files.
#

# Example: Azure Provider Usage
# This example shows how to use the Azure provider wrapper
