System Design
Getting Started
System Design is the process of designing the architecture, components, and interfaces for a system so that it meets the end-user requirements. System Design for tech interviews is something that can’t be ignored! Almost every IT giant whether it be Facebook, Amazon, Google, Apple or any other asks various questions based on System Design concepts such as scalability, load-balancing, caching, etc. in the interview. This specifically designed System Design tutorial will help you to learn and master System Design concepts in the most efficient way from basics to advanced level.
Why learn System Design?
It’s important to keep in mind that system design is an iterative process, and the design may change as new information is gathered and requirements evolve. Additionally, it’s important to communicate the design effectively to all stakeholders, including developers, users, and stakeholders, to ensure that the system meets their needs and expectations.
