What is the use of Google File System?
Google File System (GFS or GoogleFS, not to be confused with the GFS Linux file system) is a proprietary distributed file system developed by Google to provide efficient, reliable access to data using large clusters of commodity hardware.
Is Google file system still in use?
It was called the Google File System — GFS, for short. But Google no longer uses GFS. After Google released research papers describing GFS and a sister software platform called MapReduce — the piece that crunches the data — Yahoo, Facebook, and others built their own version of the Google foundation.
What is the difference between traditional file system and Google File System?
Files are divided into chunks of 64 megabytes, and are usually appended to or read and only extremely rarely overwritten or shrunk. Compared with traditional file systems, GFS is designed and optimized to run on data centers to provide extremely high data throughputs, low latency and survive individual server failures.
What is disadvantage in Google file system?
Chunk size is 64MB which is much larger than normal file system blocks. – Lazy space allocation avoids wasting space. – Disadvantages: » Small files may become hotspots.
What are the Google file system design considerations?
SYSTEM DESIGN: The authors enumerate their specific considerations as: (1) commodity components with high expectation of failure, (2) a system optimized to handle relatively large files, particularly multi-GB files, (3) most writes to the system are concurrent append operations, rather than internally modifying the …
What is a disadvantage in Google File System?
– Lazy space allocation avoids wasting space. – Advantages: » Reduces interaction w/ master. » Reduces metadata stored on master. – Disadvantages: » Small files may become hotspots. 8.
Why is Google file system scalable?
Scalability: Modularity allows GFS to easily expand to account for increasing amounts of data and users. The combination of extensibility as well as performance across increasing amounts of users and data means that the system is entirely scalable within the Google context.
Why does Google file use large chunks?
The chunk size is 64 MB; this choice is motivated by the desire to optimize the performance for large files and to reduce the amount of metadata maintained by the system. The architecture of a GFS cluster; the master maintains state information about all system components. The master controls a number of chunk servers.

What is the architecture of Google File System?
The architecture of the file system is based on a master node, which contains a global map of the file system and keeps track of the status of all the storage nodes, and a pool of chunk servers, which provide distributed storage space in which to store files.
