APIs are the interface through which different software components interact. The choice of API paradigm depends on the specific use case. models APIs based on resources using standard HTTP verbs (GET, POST, PUT, DELETE) and is ideal for public-facing APIs due to its structured and versionable nature. RPC allows code to execute on a remote machine and is more space-efficient but is often better suited for internal communications. GraphQL models data as a graph, allowing clients to request exactly the data they need, making it powerful for customer-facing apps where over-fetching data is a concern.
Requires heavy utilization of Content Delivery Networks (CDNs), multi-layered caching (Redis/Memcached), read replicas, and fan-out-on-write architectures.
Based on the specific interview question or the interviewer's interest, dive deep into 1 or 2 bottlenecks.
Rylan Liu's "System Design Interview Fundamentals" PDF guide covers a wide range of topics essential for acing system design interviews. Some of the key concepts include:
: Use peer-to-peer platforms to simulate real interview pressure and receive constructive feedback.
Separated business logic (e.g., User Service, Payment Service, Notification Service). Storage Layer: Your primary databases and caches. 4. Detailed Design and Bottlenecks (15–20 Minutes)
1M DAU, each user does 10 actions/day → ~115 QPS on average. Peaks can be 3–5× average.
If you were looking for a PDF, print this table. It is the Rosetta Stone of system design.
Calculate the Daily Active Users (DAU), Read/Write QPS (Queries Per Second), and storage requirements for 5 years. Step 2: High-Level Architecture Design (10-15 Mins)
Adding more power (CPU, RAM) to an existing server. It is easy to implement but hits a hard hardware ceiling and introduces a single point of failure.
Study guides often walk through these, detailing how to apply the fundamentals:
: Upgrading the CPU, RAM, or storage of an existing single server. This has hard hardware limits and introduces a single point of failure.
Focuses on the fan-out-on-read vs. fan-out-on-write model for timeline generation.
To effectively speak the language of system design, you must move past buzzwords and deeply understand these architectural primitives: The CAP Theorem
