Cloud Computing is considered a successful technology, involving distributed computation infrastructures, which take advantage of the virtualization of physical resources to actuate useful scale economies. In cloud ecosystems today, attention increasingly focuses on cooperation issues, mostly in the wider context of federation. Cloud federation refers to the process of interconnecting different...

Parallel Data processing has emerged to be one of the killer applications for Infrastructure-as-a-Service (IaaS) clouds. One of an IaaS cloud’s key feature is the provisioning of compute resources on demand. The computer resources available in the cloud are highly dynamic and possibly heterogeneous. Nephele is the first data processing framework to explicitly exploit the dynamic resource alloca...

Cloud computing is quickly defining the computing paradigm in the modern networked age. Users can run their large computations online using cloud services at a fraction of the cost compared to setting their own data centers. Clearly cloud computing offers many advantages, and yet many large organizations including governments, financial sector, and health care sector are reluctant in transition...

Cloud Computing plays a vital role in IT field which develop the field of computer in fast manner. Cloud Computing is nothing but sharing of resources to their clients in efficient way. It works under the concept of virtualization and by three different types of service providers such as SaaS, IaaS and PaaS. In cloud computing we come across some problems in security and data stored in the clou...

Paradigm shift towards cloud computing offers plethora of advantages both for users and Cloud Service Provider (CSP). For users, it saving cost, scaling resources, pay per use, elastic on-demand services. On the other hand, centralized resource management provisioning operations, safety security CSP. By holding multiple virtual IT resources (CPUs, storage servers, network components software) o...

Cloud Computing provides many types of services mainly SaaS, PaaS, IaaS. Each of them have their own security challenges, but IaaS undertakes all types of challenges viz., network attack and request based attacks i.e. handling the requests from untrusted users, XSS (cross site scripting attack), DDOS and many more. These attacks are independent of each other and consequently the QoS provided by...

Spot instances are a commonly offered by IaaS cloud providers to opportunistically utilize spare capacity and meet temporary user demand for additional resources at low cost. Although the availability of service SLAs is a core paradigm of cloud computing, spot instances typically come without any service quality guarantees. We aim to extend the spot instance service to provide SLAs for eviction...

Server virtualization technology achieves ”Infrastructure as a Service (IaaS)” model services. Anyone can use virtual server resource easily without preparing computer hardware, thus IaaS environments provides multiple operational benefits to users. Therefore, today various types of users, not only personal users but also enterprise users, deploy virtual resources on IaaS cloud. On the other ha...
