This is a landmark industry paper. Unlike academic approaches, industry solutions often address problems with limited resources, time, or personnel. GFS is an excellent paper because its authors deeply understand the problem and make thoughtful trade-offs. For instance, GFS opts for a single master design. While single masters are often criticized for scalability issues, this choice simplifies complexity and, with a well-thought-out design, meets the near needs of the system. However, as GFS needed to scale by several orders of magnitude, the single-master design eventually became a bottleneck. You can read more about this in a retrospective interview with a GFS engineer [2].
This paper discusses how to scale caching systems at a large scale. It trades consistency for scalability to solve practical problems encountered in production. One key takeaway is: "Separating cache and persistent storage systems allows us to independently scale them." Separation is a fundamental principle in designing distributed systems and microservices.
