Distributed File Systems: Architecture, Consistency, and Design

As data volumes grow, single-server storage solutions quickly reach their physical limits. Understanding how to distribute, replicate, and access files across a network of machines is a fundamental skill for modern software engineers and system architects. This text-only course guides you through the foundational concepts, architectural designs, and consistency challenges of distributed file systems. You will transition from understanding basic local storage to analyzing complex distributed storage topologies, replication strategies, and fault-tolerance mechanisms. What you'll learn: - Understand core terminology and the transition from local to distributed storage architectures - Analyze key design trade-offs between consistency, availability, and partition tolerance - Explore replication strategies and fault-tolerance mechanisms that prevent data loss - Examine modern consistency models, including eventual consistency and consensus basics - Compare real-world distributed file systems and modern cloud-native object storage patterns - Practice your knowledge with conceptual scenarios and written design exercises The course starts with fundamental storage definitions before exploring deep architectural patterns, communication protocols, and modern consistency models. Each section includes written self-assessments to solidify your conceptual understanding. Designed for beginner software developers, system administrators, and aspiring cloud architects, this course requires no advanced systems programming experience.
