Hand-drawn notes on system design, with demos you can run

3B Infrastructure is a notebook of plain-English explanations and hand-drawn diagrams on how software is built. Sections cover system architecture (26 topics), database concepts (9), AWS scaling (13), DevOps (19) and a 15-step VPS deploy guide, plus engineering subjects and a hand-picked course path. The maker says topics come with demos you can play and step through. The site says it is free to read with nothing to sign up for.

Hi Product Hunt, I'm Jang. I'm hunting 3B Infrastructure, I'm not the maker. It is built by Duong Phu Dong, who shared it on Unikorn (https://unikorn.vn/u/duong-phu-dong, product page https://unikorn.vn/p/3b-infrastructure), the Vietnamese community for new products. I'm hunting it because it explains system design with pictures and runnable demos instead of long pages of text.
What the site says it offers:
• System Architecture: architecture styles, trade-offs, how to design a system, and C4 diagrams at every level (26 topics)
• Database Concepts: keys, normalization, ACID, indexes, replication, sharding, CAP and NoSQL (9 topics)
• AWS Scaling: load balancing, Auto Scaling, Lambda, queues and databases that grow with you (13 topics)
• DevOps: CI/CD, Docker, Kubernetes, safe releases, observability and incident response (19 topics)
• VPS Deploy: what to do after buying a VPS and what goes wrong at each step if you skip it (15 steps)
• A Play demo button on the home page that walks a request through a tiny system step by step, and, per the maker's Unikorn post, demos on the topics too
• Free to read, with no sign-up
Good to know before you try it: it is a learning notebook, not an official AWS or vendor resource, and I haven't read every topic. The Unikorn post says 130 topics; I only counted the per-section numbers shown on the home page, which add up to fewer, so check the topic count on the live site.
Maker, if you see this: you can claim this page from the product page on Product Hunt (More, then Claim this page; Product Hunt checks an email address on your product's domain), and I'm glad to help however I can. Which topic should get a hand-drawn demo next?
