System-design case studies resurfaced
A popular YouTube/system-design feed and a 7‑case study roundup were flagged as must-watch primers covering API design, sharding, caching, concurrency and rate limiting — practical material for Google/Meta-style interviews. The posts specifically recommend real-world architectures and trade-offs rather than textbook answers shared and curated.
Hayk Simonyan’s "Systems Design" YouTube playlist — identified by the video index and descriptions — appears to match the resurfaced feed and lists 37 videos with a combined playlist view count shown as ~39,081. (youtube.com) The playlist includes a standalone "API Design 101: From Basics to Best Practices" video with ~8.2K views and a "How to Configure and Provision Database Sharding" episode explicitly named in the index. (youtube.com) The seven‑case roundup aligns with a "Solved System Design Case Studies: Quick RoundUp" post by Ignito published on Nov 16, 2022 that aggregates solved designs for Instagram, Twitter, Dropbox and other interview staples. (dev.to) Both the playlist and the roundup foreground practical trade‑offs: the Hayk Simonyan playlist description advertises "real‑world examples" and applied explanations, while the Ignito roundup presents "complete solution" case studies rather than pure textbook templates. (youtube.com) Topic coverage called out in the resurfacings maps to concrete modules — Hayk’s index lists videos on "API Security Explained: Rate Limiting" and "The Ultimate Guide to Caching and CDNs," and the roundup enumerates case studies touching sharding, caching, concurrency, and API rate limiting. (youtube.com) These resources are widely cross‑referenced in community curations used for FAANG interview prep, for example the "Awesome System Design Resources" repository that centralizes playlists and case studies and has tens of thousands of stars on GitHub.
