High Security of Data in Cloud Computing

Deepak Kumar

Abstract— Now a days, large scale distributed systems such as cloud computing applications are becoming increasingly popular. But the challenges with these applications like transferring, storing and computation of data have to be dealt with. The most prevalent distributed file systems to deal with these challenges are the Hadoop File System (HDFS) which is a variant of the Google File System (GFS). However HDFS has two potential problems. The first one is that it depends on a single name node to manage almost all operations of every data block in the file system. As a result it can be a bottleneck resource and a single point of failure. The second potential problem with HDFS is that it depends on TCP to transfer data. As has been cited in many studies TCP takes many rounds before it can send at the full capacity of the links in the cloud. This results in low link utilization and longer download times. Our work develops a mechanism of Triple security which uses a light weight front end server to connect all requests with many name nodes. Our work proposes a new distributed file system which will overcome these problems of HDFS.
