A cloud can be public, hybrid, or private. With specific access and authorization settings, aprivate cloudis a proprietary network or data center that offers hosted services to a small group of users. Cloud computing’s private or public objective is to offer simple, scalable access to computer...
A study on Security Issues Associated with Public Clouds in Cloud Computing An important issue in cloud computing is security, and it plays a major role in the cloud computing. Normally in private cloud computing there will be extremely strong password authentication, so, there will be less numbe...
Cloud computing is attractive for both consumers and providers to benefit from potential economies of scale in reducing cost of use (for consumers) and operation of infrastructure (for providers). In the IaaS service deployment model of the cloud, consumers can launch their own virtual machines (...
Security modelData storageData retrievalRetrievalData protection is considered to be a main facet in order to have a favorable development of the infrastructure of public cloud. This is due to the fact that it mainly indicates the well working of infrastructure especially for the cloud users and ...
Cloud computing is an emerging paradigm of computing that replaces computing as a personal commodity by computing as a public utility. As such, it offers all the advantages of a public utility system, in terms of economy of scale, flexibility, convenience but it raises major issues, not least...
Another dimension is the cloud business model (public, private, and hybrid clouds), which is orthogonal to the SPI service delivery model; what we highlight is the relevance of discussion points as they apply to public and private clouds. When discussing public clouds, the scope of ...
Cloud computing is the expansion of parallel computing, distributed computing, grid computing and virtualization technologies which define the nature of a new era. Cloud computing is an emerging model of business computing. It is an architecture for providing computing service via the internet on deman...

Since consumers have little control over the infrastructure so a process which requires very powerful security are not good for it .In this model no access restriction can be applied and no authorization and authentication techniques can be used. Generally, public cloud service providers like Amazon...
An overview of a public cloud computing platform is shown in Fig. 1. The cloud platform is usually equipped with high performance server machines, high speed storage devices and an efficient network. The cloud users having mobile phones, laptops or modern desktops connect to the cloud platform ...
