Explanation

Transparency to end users is a defining characteristic of server clustering. Regardless of how many physical nodes exist in the cluster, users and client applications interact with the cluster through a single virtual IP address or hostname, making it appear as one server. This abstraction means users are unaware of failovers or load distribution happening behind the scenes. This single-system image is what distinguishes a true cluster from simply having multiple servers - the complexity is hidden from the end user to ensure seamless service continuity.
