Note: Network partitions are inevitable in the real world, so modern system design is almost always a trade-off between Consistency (CP) and Availability (AP). 3. Load Balancing Strategies
A hallmark of the Liu methodology is the ability to quickly estimate scale to justify hardware and architectural choices.
A senior-level candidate is differentiated by how they handle edge cases and failure modes. The fundamentals guide dedicates significant chapters to resolving single points of failure (SPOFs), implementing rate limiting, choosing replication strategies, and designing data sharding keys. Key Technical Concepts Covered
This is where candidates sketch the primary building blocks of the system. Liu organizes this visually using a standard tier framework: Mobile apps, web browsers, IoT devices.

: Managing real-time location and driver matching.
Among the sea of preparation resources, has emerged as a highly sought-after framework. Engineers frequently search for verified PDFs and summaries of this methodology because it shifts the focus from memorizing specific architectures to mastering the foundational blueprints of any scalable system.
Round Robin, Least Connections, and Consistent Hashing (crucial for distributed caching and horizontal sharding). Note: Network partitions are inevitable in the real
What are the system constraints? (e.g., High availability vs. strong consistency, acceptable latency bounds, read-to-write ratios). 2. Back-of-the-Envelope Estimation
Draw the major components and data flow.
We worship the goddess Annapurna (food), so the kitchen is the temple. If you visit an Indian home, you will be force-fed until you physically groan. “Khao, khao” (Eat, eat) is the national greeting.
When traffic grows, your system must adapt. You have two primary paths: A senior-level candidate is differentiated by how they

Liu’s guide emphasizes that most distributed systems prioritize Partition Tolerance (P) and choose between C or A based on the use case. C. Latency vs. Throughput
When searching for , it is easy to run into broken links, outdated forum posts, or unverified files that may pose security risks to your device.
Once you scale horizontally, you need a traffic cop to distribute incoming requests across your server pool. Load balancers (like Nginx, HAProxy, or AWS ALB) operate at different layers of the OSI model:
