Scale is a relative term. While every technology needs to scale to some point to be useful to IT practitioners, not every technology needs to scale infinitely. Every technology has a context in which it is viable — where it proves to be the best choice. But in another context, the opposite technology might rise to the surface as more appropriate. Don’t be religious about such a decision. Know your business need well, research the technology thoroughly, plan for the future, and choose wisely. Don’t pick a tool that solves someone else’s problem.
