Horizontal and vertical scaling

Horizontal and vertical scaling are architectural strategies that can be applied in various domains, including software development in C++. Although scaling primarily refers to managing infrastructure and resources, it can affect software design and development.

Horizontal and vertical scaling are two fundamental approaches to handling increased demands or improving performance in computing systems. These concepts apply to various domains, including software development, databases, and server infrastructure. Let’s delve into horizontal and vertical scaling, understanding their differences, advantages, and use cases.

Horizontal scaling

Horizontal scaling, or scaling out, involves adding more instances or nodes to distribute a workload across multiple machines. In this approach, a system’s capacity is increased by expanding horizontally rather than enhancing the resources of individual devices.
