Distributed file systems
We want to know how to handle systems that have a large number of data. In previous lesson we have discovered how to quickly access and make Scalable systems with huge dimensions, see Cloud Storage. Object storage could store billions of files, we want to handle millions of petabyte files. Designing DFSs The Use Case Remember that the size of the files where heavily limited for Cloud Storage. The physical limitation was due to the limited size of a single hard disk, which was usually in the order of the Terabytes. Here, we would like to easily store petabytes of data in a single file, for example big datasets. Another feature that should be easily supported is highly concurrent access to the filesystem, last but not least being able to set up permissions in the system. ...
