Setting up high availability
Consider the scenario where we have a NetScaler sitting in front of our numerous services, and thousands of different websites that are load balanced and monitored by NetScaler.
So what will happen when NetScaler goes down, and the services stop and are no longer available for the end users? That's why we should always consider setting up a high availability NetScaler solution for our services.
By having a high availability NetScaler solution, we can ensure that if one of the appliances go down, we still have another one or more that is available to serve the requests and load balance the different services.
NetScaler has many solutions that we can use to ensure high availability. The most commonly used deployment is an active-passive pair. This means we have two appliances that cooperate so that one of the nodes is active (primary) and responds to requests and maintains the connectivity to the servers in the backend, and the other node sits passively (secondary...
