Scale Sets and Load Balancers

Scale sets provide scalable, highly-available compute, but compute in a vacuum is not useful in most cases. It is often necessary to have an additional component route traffic to the VMs in the scale set. Highly-available, platform-managed load balancers like the Azure Load Balancer and Azure Application Gateway can route traffic to scale set VMs……

If your app is hosted on a single virtual machine, this virtual machine is a single point of failure. This means that any single thing that goes wrong on this machine (hardware failure, networking blip, etc.) can cause your app to fail completely. To avoid this, Azure offers components that allow you to build a……
