Scalability
How well a system can handle more users, data or work without breaking down
What's it for?
Shows whether a system can grow to handle more people, information or work without becoming unusable.
For example…
The ticket website stays responsive when thousands of buyers arrive
A scalable ecommerce service handles ten times its normal traffic by adding more application instances rather than collapsing under demand
Think of it like…
An extendable dining table that can be made bigger when more people need a seat
