Editing Scalability (section)

==Dimensions==
Scalability can be measured over multiple dimensions, such as:<ref name="parallel_arch">{{cite book|author=Hesham El-Rewini and Mostafa Abd-El-Barr|title=Advanced Computer Architecture and Parallel Processing|url=https://books.google.com/books?id=7JB-u6D5Q7kC&q=parallel+architectures+scalability&pg=PA63|publisher=[[John Wiley & Sons]]|date=April 2005|isbn=978-0-471-47839-3|page=66}}</ref>

*''Administrative scalability'': The ability for an increasing number of organizations or users to access a system.
*''Functional scalability'': The ability to enhance the system by adding new functionality without disrupting existing activities.
*''Geographic scalability'': The ability to maintain effectiveness during expansion from a local area to a larger region.
*''Load scalability'': The ability for a [[distributed system]] to expand and contract to accommodate heavier or lighter loads, including, the ease with which a system or component can be modified, added, or removed, to accommodate changing loads.
*''Generation scalability'': The ability of a system to scale by adopting new generations of components. 
*[[Open architecture|''Heterogeneous scalability'']] is the ability to adopt components from different vendors.
