LinkedIn is the career-oriented social network that prides itself on professional excellence. But the company's original mobile offering was anything but—it left much to be desired. There was an iPhone application, but no support for Android or tablets. The backend was a rickety Ruby on Rails contraption; afflicted with seemingly insurmountable scalability problems. And despite serving only seven or eight percent of the LinkedIn population, the company's original mobile build required approximately 30 servers in order to operate. This was clearly not made to sustain a growing mobile user base.
