Vast assortment of information is store on the computer storage that we tend to referred to as as a Cloud. To shield this information from the unauthorized user cloud supplier ought to implement all doable ways that to create the cloud attack proof. during this paper we've planned a method referred to as (DROPS) Methodology, Division and Replication of Optimum Performance and Security which will create our system safer from assailant to attack the system. In our System once the information is being uploaded on the cloud the file will get divided into small fragments at multiple location exploitation T-coloring graph technique which is able to store the little data at bound distance and at the random location so attack won't be able guess the situation which will proscribe him to hack the information. within the system we can additionally perform cryptography every Fragments so if assailant hacks anybody fragments he can ready to solely hack touch of information which is able to useless for him as each fragments will have separate cryptography key to forestall assailant to hack it. when confirmatory the authentic user the quick decoding method referred to as Iris algorithmic program are use that has high speed to gather all the fragments of provided information from the sender and true information are receive to receiver. Keywords-Centrality, cloud security, fragmentation, replication, performance.
