GFS & Chubby
* [http://research.google.com/archive/gfs-sosp2003.pdf Sanjay Ghemawat et al., "The Google File System" (SOSP 2003)]

==Discussion Questions==

GFS
* What was the key task GFS was built for?
* What were the unusual design decisions made for GFS (i.e., how did they change semantics from UNIX-like filesystems)
* Why did those design decisions make sense given the task GFS was designed for?
* To what extent is GFS distributed? How is it centralized?
* How does GFS achieve fault tolerance and high performance?
* What are the different kinds of servers in GFS? What are their roles?

Chubby
* To what extent is Chubby like a UNIX filesystem? How does its semantics differ?
* Why does Chubby run on so few computers? Is it scalable?
* What is Paxos? What is it for? Why is it important to Chubby?
* What are the use cases for Chubby? How was it used with GFS?

Other
* Do you think Chubby and GFS are sufficient for Google today? Has anything changed in their use cases?
* Other thoughts or questions?
