Introduction to System Design

To excel in system design, one of the most crucial aspects is to develop a deep understanding of fundamental system design concepts such as Load Balancing, Caching, Partitioning, Replication, Databases, and Proxies.

This course will go through key concepts that can make a significant difference in your ability to tackle system design problems. These concepts range from understanding the intricacies of API Gateway and mastering Load Balancing techniques to grasping the importance of CDNs and appreciating the role of Caching in modern distributed systems. By the end of this course, you’ll have a comprehensive understanding of these essential ideas and the confidence to apply them in your next interview.

When discussing system design interviews, it's important to note that they are unstructured by nature. During the interview, it can be challenging to maintain focus and ensure all crucial elements of the design are addressed. This course should guide you in answering any system design interview question by making sure that you have not missed discussing any critical aspect.

Let's get started.
