Answer 1

Microsoft Azure Application Gateway offers layer 7 load balancing capabilities, SSL offloading, layer-7 routeing, cookie based session affinity, URL routeing and able to host multiple web application. Azure Application Gateway requires its subnet; sometimes it is confusing if you are not familiar with Azure VNet and Subnet segmentation.

First what you need to understand is the architecture pattern, how Microsoft Application Gateway would play a part in.

I have written some detail series documenting my journey throughout Azure ServiceFabric.

I would suggest you go through these posts, and it will explain Architecture viewpoint for having Application Gateway in front of Service Fabric Cluster.

Irrespective of Application Gateway, you would need Internal Loadbalancer or External Loadbalancer (depends on your topology).

2. Also try to understand how it is going to impact, security architecture of your implementation

Also, I would recommend you Reverse proxy in Azure Service Fabric.

Not fully sure your meaning, but you could create sf cluster and related resources using ARM teplates. Thats what I have done. I created appgw, cluster, vmss etc. In the virtualMachinesScalesets networkProfile you must configure the ApplicationGateway back endAddress pool instead of configuring loadBalancerBackendAddressPools. The appgw must exist before vmss deployment. You don't necessarily need lb at all. Appgw can handle the load balancing for you. Even though internal lb would bring in some nice additional features, which you could utilize later on...

I have to admit that these things are quite poorly documented...
