Cloud computing refers to Internet based distributed computing where the physical resources are pooled at one end and users across the globe can have access to unlimited resources as payasyou-go utility computing model. Cloud service users requests computing resources and cloud service provider provides them as virtual machine (VM) instances. The problem addressed here is dynamic VM creation an...

Infrastructure as a Service (IaaS) is a type of Cloud Computing service delivery model that provides compute, storage, and network resources to the consumers in an on demand manner. In IaaS cloud environment, resource allocation is one of the complex tasks due to the heterogeneous nature of cloud resources and dynamic job requirements to run the jobs. However, the IaaS cloud resource allocation...

Cloud computing promises to significantly change the way we use computers and access and store our personal and business information. With these new computing and communications paradigms arise new data security challenges. Existing data protection mechanisms such as encryption have failed in preventing data theft attacks, especially those perpetrated by an insider to the cloud provider. The us...

The present paper is an introduction of terms cloud security practices, security compliance against standards and best practices, how the cloud changes the role of IT security. Cloud computing executives have pinpointed the rise of security solutions as a key factor in the future of the IT industry. There is hardly a topic creating more of a hum in today’s’ software industry, Cloud computing is...

The actual models of cloud computing are based in megalomaniac hardware solutions, being its implementation and maintenance unaffordable to the majority of service providers. The use of jail services is an alternative to current models of cloud computing based on virtualization. Models based in utilization of jail environments instead of the used virtualization systems will provide huge gains i...

In today’s grow older the unrestrained proprietorship is to vim adequate amount of data. In conventional approach if we need about several large scale, computing machines it is painful, but spasm a times it is possible by cloud computing. Boring Contrivance supports digress processing in very efficient manner. It is energetic to hand out and complementary a large-scale pursuit on choice machine...

With the growing population and the ever growing demand for rain, the scientists and researchers across the globe are busy trying to find innovative ways to meet these ever surging demands in deforestation. This paper deals with the growth of forest by measuring Leaf area index (LAI). The collection of ground measurements for validating remotely sensed crop leaf area index (LAI) is labor and ti...

We briefly survey issues in cloud computing security. The fact that data is shared with the cloud service provider is identified as the core scientific problem that separates cloud computing security from other topics in computing security. We survey three current research directions, and evaluate them in terms of a running software-as-a-service example. 1 What is cloud computing security? Clou...

Message passing interface (MPI) has been widely used for implementing parallel and distributed applications. The emergence of cloud computing offers a scalable, fault-tolerant, on-demand alternative to traditional on-premise clusters. In this thesis, we investigate the possibility of adopting the cloud platform as an alternative to conventional MPI-based solutions. We show that cloud platform c...
