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".
