We all know technology choices have a profound impact on platform development, especially if that platform needs to scale. Choice of technology at the app server level, DB and specific design choices have an impact on scale. What about the choice of language? What does that have to do with technology choices? A strong team builds stellar software that shines. Does language have impact on the formation of the team? We all know team sets tone for culture. How does language choice impact the team culture, hiring, ramp-up, productivity? We will share the wisdom/learning of developing all Scala based scalable platform here at Verizon, ONcue. During the development of the OnCue service, we will share our experience that language choice is similar to a tip of the iceberg problem, the first area that is easy to observe but the majority of the scaling challenges are hidden and waiting to be discovered as problems arise. As we share our experience on platform development, we will also shed light on the least discussed topic on devops. What impact does a level of automation and the engineering focus on the ops team have to do with the developer productivity and the evolution of the platform.
