What does scalable mean?
Scalable describes something that can grow in size, capacity, or scope without becoming ineffective or unmanageable. The word is especially common in discussions of technology, infrastructure, products, organizations, and business models. A scalable system can handle more users, data, or demand through incremental expansion rather than requiring a complete redesign. In general use, scalable can refer to physical size, but its modern meaning often concerns adaptability and efficiency under increased pressure. The word may sound promotional when applied to a company or service, so it is useful to ask what specifically can expand and how the expansion will be achieved.

Where does scalable come from?
Scalable was formed in the 19th century from the English word scale and the suffix -able, meaning able to be. Scale ultimately derives from Latin scala, meaning ladder or staircase, through Old French. The same Latin root also underlies words such as escalate and scalar, although their meanings have developed in different directions.
