Ask HN: What programming language would you use?
Imagine you are going to write an API for a mobile telephone network operator to sell charges to customers. What platform would you use? (Specially programming language and Database). I would be grateful if you could explain about your reasons.
Comments
I would suggest any programming that you are comfortable with and use a NoSQL Database.
You can use Erlang because is not only about scalability but mostly about:
reliability
soft real-time characteristics (enabled by soft real-time GC which is possible because immutability [no cycles] and share nothing and so)
performance in concurrent tasks (cheap task switch, cheap process spawn, actors model, ...)
scalability - debatable in current state , but rapidly evolving
Anything that you are familiar with as the problem statement doesn't seems to be complex and hence can be easily done on any web platform
Erlang.
