Caching reduces latency by storing frequently accessed data in high-speed memory (like Redis or Memcached).

: Move beyond simple Round Robin. Understand Least Connections, IP Hash, and consistent hashing for stateful routing. 2. Caching Strategies

How will you handle sudden traffic spikes (rate limiting, queueing)? gaurav sen system design

A technique used to distribute data across multiple nodes while minimizing reorganization during server failures. Databases: Deciding between (for ACID transactions) and (for high scalability) based on requirements. CAP Theorem:

Among the many educators in the tech space, Gaurav Sen has emerged as one of the most popular guides for mastering this complex subject. A former software engineer at Directi and Morgan Stanley, and an IIT alumnus, his YouTube channel and structured courses have helped thousands of developers crack FAANG-level engineering interviews.

One of the first concepts you learn in the framework is the distinction between Low-Level Design (LLD) and High-Level Design (HLD). While LLD focuses on classes, interfaces, and specific functions (OOP), HLD focuses on servers, databases, load balancers, and message queues. Caching reduces latency by storing frequently accessed data

If you want to think like a principal engineer, embed these Gaurav Sen-inspired principles into your daily engineering practice:

Many engineers approach system design by memorizing specific architectures (like "How to design Twitter"). Gaurav Sen emphasizes a fundamental shift:

Copying data across multiple databases (Master-Slave architecture) to scale read operations and ensure fault tolerance. A technique used to distribute data across multiple

A cornerstone of Gaurav Sen's teaching is the practical application of the CAP Theorem. It states that a distributed system can guarantee at most two out of three properties simultaneously:

Tailoring data structures and databases based on whether the application is read-heavy (like Twitter) or write-heavy (like IoT sensor logging). 2. The Gaurav Sen System Design Framework
