This video is about designing Instagram in for a system design interview. We are expected to design the server side in a way that all 4 mentioned features can be incorporated. System Design interviews evaluate a candidate's computer science fundamentals, architecture principles and so on. We start by building an entity relationship diagram. Here the columns are defined as per the requirements. We then move to designing a microservice architecture. Each microservice defines a single component of the system. The newsfeed is built step by step with concepts like load balancing and caching as prerequisites. This completes the system design for Instagram.
