- Scaling A File Storage Backend
A six-step evolution from a single file-storage server to a scalable backend: shared metadata, load balancing and autoscaling, service boundaries and gateway auth, direct upload with presigned URLs, asynchronous events, and caching, CDN, and rate limiting.
- Attachments
An index of PDF references and diagrams attached to the system design notes, from TinyURL designs to VietQR and Discord compression charts.
- Edit History Backup
Community discussion on storing document edit history using versioned diffs with periodic full snapshots, plus comparisons to persistent segment trees, ropes, and git blobs.
- Fundamentals
An overview of system design fundamentals: the CAP consistency-availability trade-off, eight common problems with standard solutions, and a curated list of learning references.
- Non Functional Requirements
Defines non-functional requirements and capabilities, and lists the steps to gather requirements before building an application.
- Overview
A table of contents for the system design notes, covering fundamentals, software architecture, technical solutions, resilience patterns, and attachments.
- Reference Code
A pointer to a sample backend blog application on GitHub for studying application architecture.
- Technical Solutions
A curated catalog of detailed technical solutions and case studies, from JWT revocation, caching, and background jobs to TinyURL, ID generation, rate limiting, migrations, and scaling for traffic spikes.
- GonnaCrash
200Lab's free browser game at systemdesign.200lab.io. You place components, the server simulates the traffic, and a level passes only inside its success, latency, and budget limits, with up to three stars for a cheaper design.
- Sys0
sys0.in is Rakesh K's system design course, still being written: a public syllabus of 19 modules, two lessons and two labs marked free, and a yearly founding membership. Checked 2 November 2026 from this network: the founding year was shown as ₫1,408,525, opening a lesson still asked for a Google sign-in, and payments go through Dodo Payments.
- Syscraft
Syscraft is Nguyen Thanh Minh's hosted system design lab at syscraft.app: draw an architecture, run simulated traffic, and pass graded challenges. Checked 2 November 2026 without an account: the marketing page lists 7 topics and Pro at $9 a month through Lemon Squeezy, while the learn index lists 42 lessons and the challenge index lists 19.
- Breakscale
MIT discrete-event system design simulator at breakscale.tech (workersio/breakscale). The browser, the VS Code webview, and the MCP server share one engine: 33 node kinds, 23 presets, and four challenges. Checked 2 November 2026: 1,953 stars, share links seal designs with AES-GCM and keep the key in the URL fragment, and the website also loads Vercel Analytics.
