Dedicated nodes are reserved for your pool. Low-priority nodes are offered at a reduced price from surplus VM capacity in Azure. Low-priority nodes become unavailable if Azure does not have enough capacity. The sample by default creates a pool containing only 5 low-priority nodes in size *Standard_A1_v2*.
