What is horizontal scaling?

Horizontal scaling refers to adding more processing units or physical machines to the server or database. It is involved with the growth in the number of nodes in the cluster, which reduces the responsibilities of each node in the cluster. The load is reduced by providing additional end-points for client connections.

Horizontal scaling is done to increase the input/output concurrency, reducing the load on existing nodes, and increasing the disk capacity.
