As a verb, “to scale” means to make something larger or smaller than its previous size. In computers, scaled objects include visual objects such as images or fonts, or abstract objects such as data or file size. An image can be scaled, for example, using an image editor.
Scaling on the Web
On the Internet, a website or service is said to "scale" if its software and existing hardware are able to maintain its performance when the number of users suddenly increases.
The ability of web applications to “scale well” has been revolutionized by cloud computing and virtual machines. These technologies enable one-click allocation and cloning of web server resources such as bandwidth, CPUs, RAM and disk space. Cloud services like AWS, GCP, and Azure have simplified on-demand websites.
Performing web development or operational tasks at scale means working with systems that can serve a large or rapidly increasing number of users.
