This isn't something you want to avoid. Quite the contrary, in fact. Application server clustering is a method that makes it so that if a primary application server fails, a backup can seamlessly take over the functions of the failed server.

Consider a computing cluster consisting of two nodes running a databasedescribe two ways in which the cluster software can manage access to the data on the diskdiscuss the benefits and detriments of?
Consider the following two alternatives: asymmetric clustering andparallel clustering.With asymmetric clustering, one host runs thedatabase application with the other host simply monitoring it. If the serverfails, the monitoring host becomes the active server. This is appropriatefor providing redundancy. However, it does not utilize the potentialprocessing power of both hosts.With parallel clustering, the databaseapplication can run in parallel on both hosts. The difficulty implementingparallel clustering is providing some form of distributed lockingmechanism for files on the shared disk

What are some benefits of having a dedicated SQL server?
Whether it requires a dedicated server for the database, you need to consider its application importance, security, availability, performance, and manageability. Here are some thoughts for having a dedicated database server: Application Importance - If this database supports a critical application, why can't you afford a dedicated server for it to generate more revenue or benefits for the company?:-P Security - If you want to avoid unrelated people to potentially view the data, dedicated server is a choice. Availability - The other database instance(s) on the same server may be unstable and requires frequent server reboot that reduces your database availability. Performance - Your database instance may compete computer resources with other instances that may cause undesired performance to your database. Manageability - It require more coordination for many things in a shared environment and this coordination is not always an easy task.
