Designing INSTAGRAM: System Design of News Feed

This video is about designing Instagram for a system design interview. We are expected to design the server side so that all 4 mentioned features can be incorporated. System Design interviews evaluate a candidate’s computer science fundamentals, architecture principles, etc.

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 represents 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.
