The purpose of the study is to design a cloud storage service to detect the maximum probability of disrupted data blocks in a timely manner for any dynamic changes of multimedia data that does not affect the cloud environment. In the current scenario, the cloud environment must gain significant quality of service for data traversing from cloud to users. The e-learning cloud based system is alwa...

Cloud computing is one of the most emerging technologies in the world providing computing resources as a service on demand via internet maintained by third party service provider. In cloud environment trust is one of the most sensitive and important issue. In order to maintain the privacy of certain user we need strong authentication mechanism. This paper will discuss about the available authen...

There exist multitudes of cloud performance metrics, including workload performance, application placement, software/hardware optimization, scalability, capacity, reliability, agility and so on. In this paper, we consider jointly optimizing the performance of the software applications in the cloud. The challenges lie in bringing a diversity of raw data into tidy data format, unifying performanc...

Web service and Cloud computing have significantly reformed the software industry. The need for web service allocation in the cloud environment is increasing dramatically. In order to reduce the cost for service providers as well as improve the utilization of cloud resource for cloud provider, this paper formulates the web service resource allocation in cloud environment problem as a two-level ...

Cloud Computing is offering competitive advantages to companies through flexible and, scalable access to computing resources. More and more companies are moving to cloud environments; therefore understanding the requirements for this process is both important and beneficial. The requirements for migrating from a traditional computing environment to a cloud hosting environment are discussed in t...

The cloud computing is a paradigm for large scale distributed computing that includes several existing technologies. A database management is a collection of programs that enables you to store, modify and extract information from a database. Now, the database has moved to cloud computing, but it introduces at the same time a set of threats that target a cloud of database system. The unification...

Along with internet broadcasting technology, cloud broadcasting is gradually becoming the development tendency to audience view. But the problems which existed in cloud environment also may affect in cloud based multimedia streaming service area. In this paper, we proposes an approach of risk management for multimedia streaming service in cloud computing. Through previous study, we recommended ...

Cloud computing can be defined as a platform which provides different users an opportunity to store their data in the cloud. This data can be retrieved by any of the users or the service provider of that cloud. Data integrity is one of the major aspects of cloud computing services that prevails in a cloud environment. A cloud user needs to consider about data integrity apart from the confidenti...

Cloud computing provides a service based on internet for several shared resources and system software across various environment. For secure cloud storage the process of encryption of the data to the users for various needs has been brought by the delegated access control method. Generally storage in public cloud requires high communication, heavy load due to maximum storage and high computatio...

In recent years, Cloud computing is one of the most attractive technological research area because of its flexibility as well as cost efficiency. Generally in a cloud the data are transferred among the client and the server. While the transferring of the data takes place, security becomes the major concern. Efficient security system must be employed in a cloud inorder to make the computing envi...
