The application and service FACEY.TOP represents briefly how Instagram works.


But this is not a question for the interview. Or, probably, if the person has the imagination at least how to start and what is expected as a final implementation.

We need a frontend, which I would prefer to be made in Angular, React, or Knockoutjs.
We need access network with load balancing capabilities, for high availability.
I would personally make use of cloud computing instead of using my own premises network. I can make use of features provided by the cloud.
For storing images I would use services like S3 from AWS, or similar home-backed one.
For event e.g. LIKE, LOVE, etc I would use streaming (event processing) and messaging. I would need a distributed architecture because users can access images from anywhere, and latency is important in a timeline scroll on the app.

These sort of questions are open-ended so you can just use your wild imagination. Interviewers are normally checking your thinking abilities in terms of architecture and scalability.
