Systems Design Interview Concepts (for software engineers / full-stack web)

Please like the video. Ex-Google TechLead talks through core concepts for a systems design interview. Visit brilliant.org/TechLead/ to learn math, science, and computer science with new interactive courses, and get 20% off premium.

I cover the systems design interview in more detail in my program Tech Interview Pro ( techinterviewpro.com/ ) if you are interested in learning more. We also do bi-weekly Live Q&As so have a look.

In this video, we discuss load balancing, CDNs, database replication, sharding, caching layers, database schema and indexes, distributed filesystems, and other ways to scale an application. You don't want to scale your design too early or needlessly, but consider where the bottlenecks are. Sometimes you will need database sharding for instance, while other times you may not need a database at all (ie., if the data does not need to persist to disk). Note: the concepts will differ somewhat for a frontend or mobile systems design, which are more focused on the client-side architecture and software design patterns.
