Talking about system scalability in Japanese


I work at a big IT company in Japan. I'm currently working on a scalability
project, that is a project to increase the capacity of a web application.

1) How do express "scalability" in Japanese to a non-IT person? If I say
"スケーラビリティ" then pretty much no one except computer science people (an English
speakers) know what I am talking about.

2) Related to that, how do I say something like "By the end of the year the
traffic to our website will increase 500%". like what words should I use for
"internet traffic" or "number of visitors" or "number of transactions".




For general purposes, if something is "scalable", we mean it can be expanded
or extended usefully. Expansion or extension in this sense is 拡張 ( _kakuchō_ )
in Japanese. So to say it's extend _ible_ , we would say it is 拡張可能 ( _kakuchō
kanō_ ). The quality of being extendible / scalable would be 拡張可能性 ( _kakuchō
kanōsei_ ), or possibly just 拡張性 ( _kakuchōsei_ ).
