Scalability describes the ease with which you can add or remove components from a system while maintaining system reliability. As your audience grows, you may need to add servers so that the increased demand does not overload your system. Alternatively, you may want to break up a large server system into several smaller, more specialized ones. In either case, you will have to address software and hardware scalability as separate issues.
