Expanding on some of my previous posts relating to AppSense Infrastructure this post is going to talk about leveraging load balancing to make the AppSense IIS servers resilient.
So to start let me clarify that AppSense's Support Organisation will support an AppSense environment in a load balanced configuration however if they deem the problem to be caused by the load balancing technology used they will ask you to re-create the problem bypassing the load balancer. This is in line with the support stance that majority of software organisations will take.
So to start you will need to consider the following factors:
- Windows Authentication or Anonymous access to the Management and Personalization Servers.
- Do you need to configure the product through the load balanced VIP?
If the answer to the these questions are Windows Authentication and/or Yes you will need to create a service account as well as Service Principal Names (SPN.) To summarise a SPN is basically a way of mapping a service to a username.
