Installing a service application on a cluster places additional requirements on you. It is important that you keep these considerations in mind as you install any service applications on a cluster.
If so, clustering is the correct solution. Clustering will increase the availability and capacity of your applications.
You must configure the cluster correctly before installing and starting the first application that contains a service. Failure to configure the cluster correctly prevents the applications from processing requests correctly.
You must install the application on the backup cluster also.
