Horizontal scaling is a change in the number of a resource. For example, increasing the number of virtual machines processing messages in a queue. Vertical scaling is a change in the size/power of a resource. For example, increasing the memory or disk space available to a machine. Scaling can be applied to databases, cloud resources, and other areas of computing.
