Cloud Storage Systems A Survey Presented By Nitya Shankaran Ritika Sharma Motivation Important to know how our data is being stored. Need to know how your data can be stored efficiently in the cloud i.e. choosing the right kind of storage. Currently not much research is carried out on this topic. Need for a clear classification of different cloud storage systems. Recent security issue: Dropbox - deduplication of files Goals Analyzing different types of storage that cloud systems provide. - Object storage - Block storage - Relational Database storage (RDS) - Distributed File systems etc. Research on architecture of different cloud storage systems. - Amazon S3 (Object storage) - Google File System (Distributed File System Storage) - HDFS (Distributed File System Storage) - Microsoft SQL Azure (Relational Database Storage) Performance Analysis and Evaluation of each system.
