Despite these views, cloud computing is not a complete new idea as it has intricate connections to technologies or domain such as the Grid Computing paradigm, and the general distributed computing. Cloud computing is changing the way applications are deployed, monitored, and used by the end–users. The work in this paper deals to present a literature review of data security approaches for cloud computing, and evaluates them in terms of how well they support critical security services and what level of adaptation they achieve. How do wide area networks affect cloud performance? In cloud computing, the performance analysis of network resource is necessary for best use of resources as in traditional computing. "Good performance" is defined by the function taking less time than the acceptable threshold, and poor performance is defined by the function taking more time. Other factors that can affect performance which are as follows: mentioned that all of criteria listed in pe. Data size assumptions and Geographic regions, Hybrid requests (computing, networking, I / O, memory), Requests related to transmission and network, Requests related to storage and retrieval and data access. Cloud Computing is a concept that has been defined differently by many and there seem not to be a consensus. In this service model, the platforms, operating systems, applications (SaaS), and software are all available in the server. Especially, when talking about High-Performance Computing (HPC) in the cloud it is a very important aspect to proof efficient calculation speed in the cloud. How does the performance of different cloud services vary? We present a novel approach for offline Persian/Arabic intelligent word recognition based on the fast and customized dynamic time warping method. Here a series of indicators is to be identified with an objective to guide the development of cloud service related products. Starting as a database service provider, nowadays cloud computing also provides software, applications, platforms, and full functioning IT infrastructures for the clients. Cloud offers a virtually–infinite pool of resources for computing, storage, and networking resources where applications can be scaled as desired. There are three models for delivery of cloud services as follows: is the best known example of this model [1-5]. previous section but some of the factors will be important in special criteria: with this criterion is network bandwidth ,availability and scalability. A comparison among the steady-state parameters evaluated for the above queuing models with respect to traffic intensity is also presented. in a Cloud Computing environment both performance-wise and cost-wise. for time sharing, already applied in parallel and distributed systems.
