Scalability can be assessed through the ratio of the increase in system performance to the rise in resources used. Also, scalability means the ability to add extra resources while keeping the structure of the central node intact.

Why is scalability is related to performance?

If we realize that our performance requirements change (e.g. we have to serve more users, we have to provide lower response times) or we cannot meet our performance goals, scalability comes into play. Scalability referes to the characteristic of a system to increase performance by adding additional ressources.
