Over and above the IaaS bene ts described in the preceding are those of Software as a Service (SaaS). In the SaaS model, a vendor takes responsibility for not only infrastructure, but also for all of the processes required to manage an entire application solution (patches, upgrades, backups, database management, systems tuning, performance management, etc.). Because SaaS vendors manage many cus...

The adoption of the cloud computing paradigm is associated with increasing security concerns. Cloud computing service models (SaaS, PaaS and IaaS) are exposed to different security threats in each level of services. The Trusted Cloud Computing Platform (TCCP) proposes a security model that protects customers VMs at the IaaS level. In this paper, we investigate methodologies for the specificatio...

The focus of this paper is to develop an architecture using cloud for e-governance. Cloud computing offers an easy means of achieving the application model of e-Governance with multi-tenancy. We can use public Internet as a type of communication medium and provide a framework, which can be used by every citizen in spite of his or her diversity & location. This model combines SaaS, PaaS, IaaS an...

Cloud computing supplies software, platforms, and infrastructures as a service (abbr. SaaS, PaaS, and IaaS, respectively) over a network connection. From a user’s perspective, resource efficiency and scalability can be improved through aligning a cloud-based application with the cloud environment. Running an existing software system on a cloud computing basis usually involves extensive reengine...

We present the design and implementation of AppScale, an open source extension to the Google AppEngine (GAE) Platform-asa-Service (PaaS) cloud technology. Our extensions build upon the GAE SDK to facilitate distributed execution of GAE applications over virtualized cluster resources, including Infrastructure-as-a-Service (IaaS) cloud systems such as Amazon’s AWS/EC2 and Eucalyptus. AppScale pro...
