Scaling

Also called: scale, scalable, scalability, autoscaling, auto-scaling, scale up, scale out, horizontal scaling, vertical scaling

Adding capacity so a system can handle more use. Vertical scaling makes one server bigger. Horizontal scaling adds more servers. Autoscaling adds or removes capacity automatically as demand changes.

For example: A store's site slows down during a holiday sale. The host adds four more servers for the weekend and removes them on Monday.
