Quality of Service (QoS) has a significant role in the provision of resources within service oriented distributed systems. In Quality of Service, cloud computing creates new challenges for improvements using the concept of virtualization. Currently, Cloud Computing is very emerging technology in every field of data storage and resource distribution over the network. Considering this new emerging technology, for the ease of data accessibility, price, resource use, restoration, response time and number of constraints the quality performance measures need to be upgraded. The paper highlights the research gap in providing a solution to achieve a Quality of Services in Cloud Computing. We also review the issues and challenges arising in cloud computing to guarantee quality.

“…Finally it should be noted that information security is also a technological challenge, but due to its importance it is treated separately. Moreover information security is not only a technical issue, it also relates to organizational aspects, governance [15,16]. The issue of standards and interoperability exist since the early days of the computer business.…”

Nowadays, there has been fast growth in cloud computing and social networking technologies. Cloud computing translates the computing resources to a third party, eliminating the need to purchase, configure and maintain those resources. With the increasingly ubiquitous nature of Social networks and Cloud computing, users are starting to explore new ways to interact with, and exploit these developing paradigms. Social networks are used to reflect real world relationships that allow users to share information and form connections between one another, essentially creating dynamic Virtual Organizations. Cloud Computing and Social Network Sites (SNS) are among the most controversially discussed developments in recent years. The opportunities of using powerful computing resources on demand via the web are considered as a possible driver for the growth of the world economy. Social networks provide a virtual place where people can interact and share. With the increasing user base and the competition social networks needed a scalable, cost-effective backend architecture and efficient business. Online social media network has become part of human life by transforming the way users create new social relations or relate with family and friends. A social network, as the name suggests is a network of individuals created for social communication. It is a massive platform where people interact with others anywhere in the world online based on some relationship. The relationship can be friendship, family membership or others with some shared interests. Despite these considerable benefits, there are serious concerns and challenges about this new technology. The most important issue is related to security and privacy subjects in cloud-based environments. Accordingly, challenges and concerns related to cloud based environments have been identified and most appropriate current solutions for each challenge have been described. In overall, it is anticipated that cloud computing will be the most important and challenging issue in IT industry. As regarding the importance of this technology, we hope this paper will contribute to a better understanding of the vision of cloud computing and the challenges ahead for further researches. Likewise, social networks have seen enormous growth, with millions of Internet users actively participating across various social networking websites.

Cloud computing is a technology in the field of computing which offer services to the customer from anywhere at any time [1]. In the cloud, resources are shared all around the work for quick servicing to the customer. The aggregation of two terms is referred as cloud computing. The term “cloud” is a pool of different resources offers services to the end customers and “computing” is done based on the Service Level Agreement (SLA) to make the resources efficiently to the customers. Load balancing is an important challenge in the environment of the cloud to increase the utilization of resources [3]. Here we proposed an algorithm which is based on load balancing and service broker policy. We user two representative thin the proposed approach local representative and global representative Local user representative is used to predict the parameters of user task and based on priority it allocate the task to the Virtual Machine (VM). Then for scheduling the task and provide the services to the users based on the available cloud brokers global user representative used Dynamic Optimal Load-Aware Service Broker (DOLASB).we used two scenario with different no. of user requests , in these scenario result of our proposed method is better as compared with the other existing methods in terms s of Execution Time, Makespan, Waiting Time, Energy Efficiency and Throughput.
