Cloud computing has created a paradigm shift that affects the way in which business applications are developed. Many business organizations use cloud infrastructures as platforms on which to deploy business applications. Increasing numbers of vendors are supplying the cloud marketplace with a wide range of cloud products. Different vendors offer cloud products in different formats. The cost str...

cloud computing is a new discussion in enterprise it. it has already become popular in terms of distributed technology in some companies. it enables managers to setup and run the intended businesses by avoiding excessive spending on computers, software and hiring expert staff, which proves to be cost effective. cloud computing also helps users pay for the it services without spending massive am...

The vulnerability of Cloud Computing Systems (CCSs) to Advanced Persistent Threats (APTs) is significant. So a cloud architecture reference model that incorporates a wide range of security controls and best practices, and a cloud security assessment model – Cloud-Trust – that estimates high level security metrics to quantify the degree of confidentiality and integrity offered by a CCS or cloud ...

Cloud computing refers to services that run in a distributed network and are accessible through common internet protocols. It merges a lot of physical resources and offers them to users as services according to service level agreement. Therefore, resource management alongside with task scheduling has direct influence on cloud networks’ performance and efficiency. Presenting a proper scheduling ...

Virtualized cloud infrastructures are very popular as they allow resource mutualization and therefore cost reduction. For cloud providers, minimizing the number of used resources is one of the main services that such environments must ensure. Cloud customers are also concerned with the minimization of used resources in the cloud since they want to reduce their invoice. Thus, resource management...

As we know that now a days the use of computing services is rapidly increasing over internet, so there is a need to buy mainframe system for every enterprise to full fill the requirements of end users and this can be overcome by use of cloud computing services in a inexpensive manner. Cloud computing paradigm offers a wide range of computing services for enterprises in terms of elasticity, serv...

The cloud computing is considered as a computational model which provides the uses requests with resources upon any demand and needs.The need for planning the scheduling of the user's jobs has emerged as an important challenge in the field of cloud computing. It is mainly due to several reasons, including ever-increasing advancements of information technology and an increase of applications and...

Cloud system is gaining the importance in public environment. But security is always a critical challenge while sharing the valuable information. In this work, a high level integrated security model is presented for managing large data on cloud system. In this work, a RSA integrated SHA method is presented to provide the secure file management in distributed cloud. The proposed authentication a...

The article describes methods for dealing with reliability and fault tolerance issues of cloud datacenters. These methods are mainly focused on the elimination of single point of failure within any component of the cloud infrastructure, including the availability of infrastructure and accessibility of cloud services. The methods for providing the availability of hardware, software and network c...
