can we use load balancer on a two app services in azure

Question

I am creating a network with 2 app services, containing 2 slots each I know the load balancers are designed to work with VM's, but I am wondering if it is possible to place a load balencer on these 2 app services to balance the load between them, Is it possible to do so??

Answer 1

When you Scale your Web App you add instances of your current pricing tier and Azure deploys your Web App package to each of them. There's a Load Balancer over all your instances, so, traffic is automatically load balanced between them. You shouldn't need a Virtual Machine for this and you don't need to configure any extra Traffic Manager.

According to your description, maybe you are looking for Azure application gateway(layer 7).

Azure application gateway works at the application layer (Layer 7 in the OSI network reference stack). It acts as a reverse-proxy service, terminating the client connection and forwarding requests to back-end endpoints.

Azure application gateway support HTTP, HTTPS and Websockets.

Here is the features offered by each service:
