Andrew File System: Crash Recovery & Consistent Caching Fundamentals

In distributed systems, ensuring data integrity and continuous operation despite failures is paramount, especially when client-side caching is involved. This course will equip you with a fundamental understanding of how robust distributed file systems manage crash recovery and maintain consistent data across multiple clients and servers, using the Andrew File System (AFS) as a practical case study. You will learn the core concepts that underpin reliable distributed computing. Learn the architecture and challenges of distributed file systems. Explore the critical role of caching in distributed environments and its consistency challenges. Learn how Andrew File System (AFS) implements crash recovery mechanisms. Apply principles of fault tolerance and data integrity in distributed caching scenarios. Analyze different consistency models and their implications for system design. Practice identifying potential points of failure and recovery strategies in distributed systems. The course begins with an introduction to distributed file systems and their unique requirements, then delves into the intricacies of client and server-side caching. You will then systematically explore AFS's approach to crash recovery, understanding how it ensures consistent data states even after system failures, and conclude by examining broader concepts of distributed consistency. This course is designed for beginners interested in distributed systems, network file systems, or system reliability. No prior experience with distributed computing is required.
