The Google File System and its application in MapReduce

In the need for a scalable infrastructure supporting storage
and processing of large data sets, Google has developed a number of
cluster-based technologies which include the Google File System (GFS)
and MapReduce.

This paper aims at explaining the key ideas and mechansims deployed
in the Google File System and illustrates the architecture and fault tolerance
features implemented. To highlight the role of the Google File
System in Google’s software landscape, MapReduce as a technology for
data processing that leverages the services provided by GFS is presented.
Along the discussion of these systems, key dierences to other approaches
regarding design and implementation are pointed out.
