- Services that use multiple ports or configurations that provide multiple services are not supported.
- Internal Load Balancing or ILB – This is a function that enables load balancing between virtual machines that reside inside Azure cloud services or virtual networks with limited regions.
- [VIP protected with IP resources] – A virtual IP address created with LifeKeeper.
- [VIP configured by ILB] – A virtual IP address of the Internal Load Balancing created in Azure.
- [Azure private IP address] – A private address used in Azure Virtual Network.
