Scalability

Ability of a system to handle growth efficiently.

Scaleability

Scalability derives from 'scale' meaning the extent or range of something.

Scalability means a system can handle more users or data without slowing down, like adding more shelves to a bookcase when it gets full.

Scalability is a key consideration in designing large-scale systems like Google and Amazon
Horizontal scaling, adding more machines, is often preferred over vertical scaling, upgrading a single machine
Early computer systems had very limited scalability

What is scalability? It's the ability of a system to handle increasing amounts of work
Why is it important? To ensure systems remain responsive and efficient as demand grows
How is scalability achieved? Through techniques like cloud computing, load balancing, and database optimization
