    As the video discussed there are many capabilities and I don’t see what walking through creating one in 2 minutes would really add. There are lots of documents that walk through creation, my goal was to explain capabilities that would help you decide if it’s a fit and what configuration. If you want to see a demo I create and show config in the aks network deep dive.

    Very good video...do we need to choose session persistence option when handling network symmetry for NVA behind a Azure Load balancer or would the HA port feature suffice? Also, you did mention Azure LB supports "stickiness" in what scenario would one then chose a Session Persistence option. Thanks

  • @NTFAQGuy

    @NTFAQGuy

    for NVAs and symmetry that is the HA port option. separate the 5,3,2 tuples controls how sticky it will be and you pick based on the need to go to same backend based on variations in port/protocol.

    Hi John, As I read we have provision of having a load balancer integration option with App Service. In a normal case when we have a Azure Web app we would have a single end point , so am i correct to conclude it will not add a value in such cases. Also could not think over when we would have a use case where we have multiple end points and LB is useful with App Service. Usually such balacing acts is done within a given app and not across app? Sorry if i sound foolish but love to get ur feedback !
