Infrastructure as services (IaaS) in Cloud computing offers the features of increasing the hardware resources (CPU cores, RAM, hard disk or storage space, and network bandwidth) on-demand in no time or utilizing the additional configured VMs to execute the business applications in a shortest time as possible by utilizing the dynamic scaling. The scheduling algorithm in the IaaS allows the appli...

Infrastructure as a Service (IaaS) operators need to balance multiple adversarial goals, such as data center performance and energy efficiency. Automated resource management policies implemented in IaaS Cloud middleware allow the operators to automate trade-off decisions. Simulation-based analyses are viable means to validate that the utilized policies achieve the goals of the operator. For an ...

The cloud computing model transforming the IT landscape. Cloud computing is a new computing paradigm that delivers computing resources as a set of reliable and scalable internet allowing customers to remotely run and manage these services. Infrastructure-as-a-service (IaaS) is one of the popular cloud computing services. IaaS allows customers to increase their computing resources on the fly wit...

Cloud Computing is an emerging area for accessing computing resources. In general, Cloud service providers offer services that can be clustered into three categories: SaaS, PaaS and IaaS. This paper discusses the Cloud workload analysis. The efficient Cloud workload resource mapping technique is proposed. This paper aims to provide a means of understanding and investigating IaaS Cloud workloads...

Infrastructure as a Service (IaaS) is a delivery model of cloud computing, which provides the ability to users to acquire and release resources according to their demand and pay according to their usage. Resources are provisioned from the cloud as Virtual Machines (VMs), many of which can be deployed on a single computing node, realizing a multi-tenancy model. While virtualization and multitena...

Services computing is penetrating IT and computing technology at every level, encompassing the Web, the cloud, big data, business process modeling, and more. One feature that distinguishes cloud computing from conventional distributed computing is its hierarchical organization of computing capabilities as services, represented by infrastructure as a service (IaaS), platform as a service (PaaS),...

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...

Different cloud platforms offer similar services with different characteristics, names, and functionalities. Therefore, describing cloud platform entities in such a way that they can be mapped to each other is critical to enable a smooth migration across platforms. In this paper, we present a DSL that uses a common cloud vocabulary for describing cloud entities covering a wide variety of cloud ...

In IaaS services of cloud the customers demand for hardware resources as a service like memory, processor cycles, disk storage even software. IaaS services of cloud rely heavily on virtualization. The service is provided by means of virtual machine. It is not easy task for cloud users to store their valuable data over cloud because of matter of trust over cloud. Data integrity in cloud environm...
