Round 5: [Code Design- wherein the scalability and code reusability was tested]

• Design a language translation system with integrating 3rd party api for translation.
• Follow-up:
  Reduce the api call because per word costing 5c.
  The local cache would be inmemory and cannot be stored in harddrive
  There would be flawed word translated which has a time buffer of two hours, as in the word cache before 2hrs from now could be flawed so return the translated word correct and not flawed.
  How and when you'd test the system, what all metric you'd use for monitoring the system.
