Cloud computing is a new era in computing paradigm. It helps Information Technology (IT) companies to cut the cost by outsourcing data and computation on-demand. Cloud computing provides different kind of services which includes Hardware as a Service, Software as a Service (SaaS), Infrastructure as a Service (IaaS) etc. Despite these potential benefits, many IT companies are reluctant to do clo...

Validating a new application over a Cloud is not an easy task and it can be costly over public Clouds. Simulation is a good solution if the simulator is accurate enough and if it provides all the features of the target Cloud. In this report, we propose an extension of the SimGrid simulation toolkit to simulate the Amazon IaaS Cloud. Based on an extensive study of the Amazon platform and previou...

This paper is about deploying Honeyd, a virtual honeypot that simulates different operating system on Eucalyptus Iaas cloud and usage of proposed encryption methodology on data to make data access secure. The data collected in capture mode is analyzed to prevent further exploitation of system. KeywordsHoneypot; Honeyd; Virtual Honeypot; Iaas; Low interaction honeypot

The success of the Cloud computing paradigm, together with the increase of Cloud providers and optimized Infrastructure-as-a-Service (IaaS) offerings have contributed to a raise in the number of research and industry communities that are strong supporters of migrating and running their applications in the Cloud. Focusing on eScience simulation-based applications, scientific workflows have been ...

Cloud Computing is becoming more and more popular, and various cloud services have appeared to make our lives easier. Mobile devices can also benefit from Cloud services: the huge data users produce with these devices are continuously posted to online services, which may require the modification of these data. Using cloud storage services together with computation-intensive infrastructure servi...

The ability to measure the energy consumed by cloud infrastructure is a crucial step towards the development of energy efficiency policies in the cloud infrastructure. There are hardware-based and software-based methods of measuring energy usage in cloud infrastructure. However, most hardware-based energy measurement methods measure the energy consumed system-wide - including the energy lost in...

Users of cloud computing are overwhelmed with choice, even within the services offered by one provider. As such, many users select cloud services based on description alone. We investigate the degree to which such strategy is optimal. In this quantitative study, we investigate the services of 2 of major IaaS providers. We use 2 representative applications to obtain longitudinal observations ove...

Cloud computing and Infrastructure-as-a-Service (IaaS) are emerging and promising technologies, however their adoption is hampered by data security concerns. At the same time, Trusted Computing (TC) is experiencing an increasing interest as a security mechanism for IaaS. In this paper we present a protocol to ensure the launch of a virtual machine (VM) instance on a trusted remote compute host....

Recently, a growing development and use of Cloud computing services has been observed. Especially modeling cross-organizational cooperation and the respective provider comparison are gaining importance. Despite initial positive results, it is challenging in theory and practice to find an appropriate provider matching the individual requirements. Moreover, the comparison process is complicated b...
