Cloud computing is growing now-a-days in the interest of technical approach can be improved much by using cloud computing instead of traditional ict. a significant number of secure systems are concerned with monitoring the environment. then there are equipment to measuring consumption of utilities. at the top end of the scale, there are systems used to verify security issues, there are also security systems, monitoring systems are also important because they have quite a lot in common with systems designed to enforce the copyright of software and other digital media. the objective of this work is to investigate whether we can build capacity of client-server disruption network directly over cloud using network forensics. it is a mechanism of centralized computing. a sector of available resources such as applications, processes and services can be rapidly deployed, scaled and provisioned, on demand. for this reason using cloud mputing to deliver on demand forensic services could be an effective new way to support framework of client-server model allowing cloud organizations, service providers and customers, to establish forensic capabilities and reducing cloud security risks. the server-side will be responsible for acknowledging the fragments received and forwarding them to selected client using mechanism of centralized computing. to allow forensic tasks, such as network forensics, be split and performed in centralized on one server, a forensic image can be considered as the natural unit of storage and processing. it is possible to run remote processes on a server capable of caching in ram and processing image files, allowing complex forensic tasks to be quickly performed in centralized. developed 'rpgcloud' algorithm (rpgca) for trying to virtualize the server for daily basis backups, server monitoring, utilization of cpu. this approach can be improved by using cloud computing instead of traditional ict. a significant number of secure client systems are concerned with monitoring the environment by the end-server.
