These are long term Reservation plan and short term On-demand plan. Cloud Computing is highly cost effective because it operates at higher efficiencies with greater utilization. There are a number of factors to be considered when planning to use cloud services, … Generally the meaning of cloud computing In this paper we will give an overview about our work. Cloud computing [23] is a promising paradigm for the provisioning of IT services. Lau, Senior Member, IEEE Abstract—On-demand resource provisioning in cloud computing provides tailor-made resource packages (typically in the form of VMs) to meet users’ demands. Virtual machine (VM) provisioning is a common and critical problem in cloud computing. )Public b.) Platform as a Service Abstract—By leveraging the elasticity of cloud computing, cloud radio access network (C-RAN) facilitates flexible resource management and is one of the key techniques of enabling 5G.

Introduction Cloud computing, also referred as simply “the cloud”, which is providing the on-demand resources to applications from data centers through the Internet based on pay-for-use policy. It just requires an Internet connection. The term virtualization is often synonymous with hardware virtualization, which plays a fundamental role in efficiently delivering Infrastructure-as-a-Service (IaaS) solutions for cloud computing. Private c.)Hybrid. IEEE TRANSACTIONS ON CLOUD COMPUTING, 2014 1 Heuristic-based Optimal Resource Provisioning in Application-centric Cloud Sunirmal Khatua, Member, IEEE, Preetam K. Sur, Rajib K. Das and Nandini Mukherjee, Senior Member, IEEE Abstract—Cloud Service Providers (CSPs) adapt different pricing models for their offered services. A company interested in cloud computing is looking for a provider who offers a set of basic services such as virtual server provisioning and on­demand storage that can be combined into a platform for deploying and running customized applications. 2.The elimination of an up-front commitment by cloud users. cloud computing acquisition and pricing models (e.g., spot and on-demand instances), considers real-time pricing information across instance types and availability zones, migrates spot re-quests to satisfy waiting jobs, and can use on-demand instances when spot requests are not fulfilled within a customizable period of time. infrastructure services for provisioning computing and storage resources, and expectedly they will evolve into general IT resources, providing a basis for true New Generation Networks (NGN) as defined by ITU-T [1, 2]. Cloud Computing for on-Demand Resource Provisioning THANK YOU FOR YOUR ATTENTION!!! Ans: Wide network access, scalability, security, location and device independence, cost reduction etc. Prior efforts have addressed this challenge based on either a cost-oblivious approach or … •NIST Definition of Cloud Computing "Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction." In cloud computing As per definition of National Institute of Standards and Technology (in updated version of pdf), Provisioning in Cloud Computing is one of the feature of Cloud Computing itself. • Virtualization has already reduced service provisioning time from 90 days to 14 days. Cloud Computing offers on -demand self service. The simulation services orchestrated by these workflows are typically used only rarely and irregularly, keeping them running all the time would result in a significant waste of resources. This computing paradigm basically adopts the client-server architecture and facilitates centralized deployment and computation offloading for applications. Cloud providers usually offer various types of VM in-stances at different prices, with varying compute, network, and storage capabilities. Cloud providers can offer cloud consumers two resource provisioning plans, namely short-term on-demand and long-term reservation plans. Resource provisioning with single-type cloud instances (i.e., with on-demand … The simplicity of the interface between cloud service providers (CSP) and multi-tenants has vitally contributed to the fame of cloud data centers presents on-demand use of the computing resources. Cloud Computing offers load balancing that makes it more reliable. On-demand Cloud Resource Provisioning Xiaoxi Zhang, Student Member, IEEE, Chuan Wu, Senior Member, IEEE Zongpeng Li, Senior Member, IEEE and Francis C.M. Cloud consumer has to pay to provider according to the state plan, the customer can decrease the total resource provisioning cost. Cloud providers also offer different pricing models. 5.) What type of cloud computing model fits these requirements? II. on-demand resources and the reservation of resources from the results. The computing resources are provisioned by cloud resource provisioning model. of resource provisioning in cloud computing environments. 3.1 System model and assumption The system model and assumption of cloud The machines can be scale up and down on demand with a high level of resources’ abstraction. We solve the resource provisioning problem by formu-lating an optimization problem that aims at minimizing the long-term average system cost. Ans: a. cloud is the key to handle the growing range of workloads that pressure network resources in the data center. In practice, a huge num-ber of VMs are provisioned per day in industrial cloud plat- Options are: A.) In cloud computing, the main drawback is relevant to the best use of resources as well as resource provisioning. The three categories: with on-demand instances, with reserved instances and hybrid strategy. The OCRP algorithm can be used as a resource provisioning tool in which the tool can effectively save the total cost for the emerging cloud computing market. In 2009, to help explain the excitement around cloud computing, \The Berkeley View on Cloud Computing" [2] identi ed six potential advantages: 1.The appearance of in nite computing resources on demand. delivering different resources, the cloud supplier provides computing power for the cloud users to organize their multiple type of application at any time on different platforms. Ans: True; Type of cloud. Dynamic resource provisioning is a challenging technique to meet the service level agreement (SLA) requirements of multi-tier applications in virtualization-based cloud computing. For instance, Amazon EC2 cloud providers offer both plans but on-demand … DaaS is utilized for provisioning critical data on demand. 3.The ability to pay for use of computing resources on a short-term basis as needed. The provided resource plans are reservation and on demand. Cloud computing infrastructures, such as those offered by the RESERVOIR project, aim to facilitate the deployment, management and execution of services across multiple physical locations in a seamless manner. What is public cloud? As a consequence, we developed the approach of on-demand provisioning of workflow middleware and services.

Montero OpenNEbula is partially funded by the “RESERVOIR– Resources and Services Virtualization without Barriers” project An Integrated Model for Secure on Demand Resource Provisioning Based on Service Level Agreement (Sla) in Cloud Computing Resource provisioning consists of two provisioning plan for allocating resources in cloud. E.g., Amazon EC2 provides on-demand, reserved, and spot instances. Provisioning in Cloud Computing is the process of on demand self service on pay as you go model to get new services or scale existing services as per need. There are two provisioning policy for computing resources that is reservation and on-demand plans. Characteristics of cloud computing? Managing up-layer cloud services efficiently, while promising those advantages and SLA, motivates the challenge of provisioning and allocating resource on-demand in infrastructure layer, in response to dynamic workloads. Implementing On-Demand Services Inside the Intel IT Private Cloud • On-demand self-service improves business agility by unlocking the full business value of our cloud computing environment. Cloud Computing technologies are emerging as a common way of provisioning infrastructure services, applications and general computing and storage resources on-demand. Keywords: Cloud Computing, Green Computing, Resource Management, Virtualization 1. flexible access to IT resources, on-demand and self-service service request are some key advantages of it. In general, cloud providers can offer the cloud consumer with two provisioning plans for computing resources, namely (long-term) reservation plan and (short-term) on-demand plan [11]. RESOURCE PROVISIONING In cloud computing, a resource provisioning mechanism is required to supply cloud consumers a set of computing resources for processing the jobs and storing the data. 2.1 Cloud Computing Cloud computing concerns the provisioning of resources, including computation, memory, storage, network, and applications/services, over the Internet. "Policies should be used on demand when and where you need them," he said. Despite existence of the cloud services mega-providers, cloud based services provisioning may Reservation plan is long term plan and On-demand plan is a short term plan. It does this by assigning a logical name to a physical storage and providing a pointer to that physical resource on demand. Recently, cloud computing has emerged as a new comput-ing paradigm that offers a variety of services [Wang et al., 2015]. The resources can be used without interaction with cloud service provider. Cloud providers are charge for these computing resources based on cloud resource usage. Cloud computing is a form of distributed computing1 that enables access to a scalable and elastic pool of shareable resources with on-demand provisioning and administration. • On-demand self-service has the Cloud computing requires a provisioning method for allocating resources to the customers.
