Azure has two methods of load balancing services out of the box. Depending on your needs and the security requirements of your company will help decide the method that you will use. I have detailed both methods in two blog posts below. Be sure to reference the Microsoft link for the details on both and decide what method is best for your company.
Method 1 – Azure Internal Load Balancing (ILB)
Azure Internal Load Balancing (ILB) provides load balancing between virtual machines that reside inside of a cloud service or a virtual network with a regional scope
Configure the AD FS Servers in an Internal Load-Balanced Set in Windows Azure for Office365 Single Sign-On
With this method you have one network with different address spaces for the internal (10.0.0.0) and DMZ (172.16.0.0) networks. This method works, because Azure allows routing between the different address spaces on the same network.
Method 2 – Azure Load Balanced Set
Azure load balanced set is layer 4 load balancing across the virtual machines of a cloud service
Configure the AD FS Servers with Azure Load Balanced Set in Windows Azure for Office365 Single Sign-On
With this method, you have two physical networks in Azure. With this method, we rely on end points and hosts files for routing between the networks. This is the more secure way of implementing the solution since we will control access with ACLs between the networks.
