Study 50 system design concepts

Two widely shared study resources are giving software engineers a compact way to review system design before senior-level interviews and platform work. Ashish Pratap Singh’s GitHub repository, “Awesome System Design Resources,” collects free material on topics ranging from scalability and CAP theorem to CQRS, circuit breakers and disaster recovery. System Design School, a separate training site, presents a structured curriculum covering web-scale design, high availability, messaging, replication and stream processing. The two resources overlap on the same core problem: system design is broad, and candidates often struggle to turn scattered concepts into a repeatable interview approach. Singh’s repository says it is meant to help engineers “learn System Design concepts and prepare for interviews,” while System Design School says it teaches system design “the structured way” with templates and practice. (github.com) ### What does the GitHub resource actually include? Ashish Pratap Singh’s repository organizes system design into topic clusters rather than one long reading list. The page groups material under core concepts, networking fundamentals, API fundamentals, database fundamentals, caching, asynchronous communication, distributed systems and architectural patterns. It also lists tradeoffs such as vertical versus horizontal scaling, strong versus eventual consistency, and synchronous versus asynchronous communication. (github.com) The same repository also links interview-style design prompts. GitHub’s page shows examples including URL shortener, autocomplete, load balancer, CDN, distributed key-value store, distributed cache and authentication system. That makes the resource useful as both a glossary and a drill sheet for interview preparation. ### Which concepts matter most if you are studying for staff-level interviews? (github.com) System design interviews usually test whether a candidate can connect a few recurring ideas under pressure. AlgoMaster’s “Top 30 System Design Concepts,” also by Singh, says most real-world systems and interview problems are built on “the same small set of core ideas,” then groups those ideas into networking, APIs, data storage, scaling, distributed systems and architecture patterns. (github.com) In practice, that means engineers need more than vocabulary. Concepts such as idempotency, rate limiting, sharding, replication, pub/sub, service discovery, consensus and distributed tracing tend to show up together because they describe how systems behave under load, partial failure and growth. Singh’s repository reflects that pattern by placing those ideas next to one another instead of treating them as isolated terms. (algomaster.io) ### How is the structured course different from a link collection? System Design School presents itself as a guided course rather than a catalog. Its site says the material covers “every main aspect of system design, from fundamentals to advanced topics,” including non-functional requirements, high availability, resource estimation, microservices, synchronous and asynchronous communication, CQRS, replication, partitioning and stream processing with Flink and Kafka Streams. (github.com) That format matters for candidates who already know the terms but need a sequence. A repository is efficient for breadth and revision; a course is better for building a repeatable framework for answering open-ended prompts, especially when the prompt moves from “design WhatsApp” to “design a resilient comment system” or another production-style case. That is an inference from the way the two resources are structured. (systemdesignschool.io) ### How should an engineer use both without wasting time? GitHub’s repository is better suited to fast coverage. The page can serve as a checklist for gaps in basics such as DNS, proxies, load balancing, ACID transactions, cache eviction, CDC, circuit breakers and disaster recovery. A structured platform is better suited to repetition. System Design School emphasizes templates, practice and feedback, which makes it more useful once an engineer has already identified the core building blocks and needs to rehearse tradeoffs, scope and failure handling in a timed setting. (github.com) GitHub shows Singh’s repository had 37,300 stars and 8,000 forks at the time of capture, suggesting the list has become a widely used reference point. (github.com) System Design School continues to advertise modules on CQRS, replication, partitioning and stream processing, giving engineers a next step after the broad survey. (systemdesignschool.io)
