Definition

compound. adding more power, like a faster processor or more memory, to a single computer or server to help it handle more work.

compound. the process of increasing the capacity of a single machine or node by adding resources such as CPU, RAM, or storage. Often contrasted with horizontal scaling, which involves adding more machines to a system.


SIMPLE

We chose vertical scaling by adding more RAM to our main server.

CONTEXTUAL

When the database started running slowly during peak hours, the team decided on vertical scaling to increase the server's processing power.

COMPLEX

Vertical scaling offers the advantage of simplicity in software architecture, as it avoids the complexities of distributed computing, though it is eventually limited by the hardware specifications of a single machine.

Origin

A compound of vertical, from the Latin verticalis meaning overhead, and scaling, from the Latin scala meaning ladder. The term follows a geometric metaphor for expansion, contrasting with horizontal scaling to denote growth along a single axis of capacity.
