Thiết Kế Hệ Thống Cho Người Mới Bắt Đầu: Xây Dựng Hệ Thống Backend Có Khả Năng Mở Rộng

System design is one of the most important skills for any backend or full-stack developer — but most tutorials are either too advanced or too abstract. This beginner-friendly course is designed to help you build a strong foundation in system design by focusing on real-world concepts used by top tech companies.

You’ll start with the basics: how modern web apps are structured, what makes a system scalable, and how production architectures are actually built. Then we’ll dive into the key components of backend systems — covering networking essentials, APIs, caching, CDNs, proxies, databases, and load balancing.

You’ll learn how SQL and NoSQL databases work, what ACID properties mean, how to scale reads and writes, and when to use object storage like BLOB. I will also explain CI/CD pipelines, MapReduce, and how big data is processed at scale in distributed systems.

By the end, you’ll not only understand how to design backend systems — you'll also be ready to tackle common system design interview questions like designing YouTube, Twitter, or a file storage service.

Whether you're a junior developer, bootcamp grad, or mid-level engineer, this course will give you the practical, job-ready knowledge you need to grow your backend skills and build better systems.
