what is a clustered database

A clustered database is a type of database architecture that uses multiple servers or nodes working together to provide high availability and scalability. In a clustered database, data is distributed and replicated across multiple servers, and each server operates as part of a single database cluster.

A clustered database allows for increased reliability and availability, as data is replicated across multiple servers, and if one server fails, the database can continue to operate without interruption. Additionally, clustered databases can be scaled out to accommodate larger amounts of data and higher levels of traffic by adding more servers to the cluster.
