Cloud storage is basically giving all the data to a third party to store it and to retrieve them whenever we wish. This compromises the security of the data. So high security measures are meant to be taken but, it should be simple and easy to use. To overcome these disadvantages, we come with the technique, Division and replication of Data in the Cloud for Optimal performance and Security (DROPS). In the DROPS methodology, we use many number of cloud servers. To upload a file, it is divided into many fragments, and replicate the fragmented data over the cloud nodes. Each of the nodes stores only a single fragment of a particular file so that even in the case of a successful attack, no meaningful information is revealed to the attacker. The Cloud Manager or simply the CM takes care of all these activities and during the retrieval of a file, the cloud manager collects all the fragments of a file and combines them to form the original file and is given to the user. The main idea is to give added security and protection against all types of attacks, to the data that is being stored in cloud storages Keywords: Cloud storage,
