What is the term for using multiple servers to manage user requests effectively?

The term for using multiple servers to effectively manage user requests is server redundancy. This practice involves having multiple servers in place so that if one server fails or becomes overloaded, others can take over to handle the user requests without interruption. This approach not only ensures high availability and reliability of services but also balances the load among servers, preventing any single server from becoming a bottleneck.

Server redundancy is crucial for maintaining performance, especially in environments where uptime is critical, such as web hosting, cloud services, and critical business applications. It enhances the scalability and resilience of the system, allowing organizations to efficiently accommodate surges in user demand without service degradation.

In contrast, data encryption focuses on protecting data through secure coding practices; network failure is a scenario that server redundancy aims to prevent; and data replication involves copying data from one location to another, which is different from the concept of balancing and managing user requests across multiple servers.
