Cost issue always is one of most important issue for enterprise in building their IT platform. With the advance of various cloud environments, enterprise’s IT executive may have different consideration in constructing their IT platform. For example, constructing an own cloud environment or renting a computing platform from cloud providers. This paper the authors, based on the Net Present Value in Finance field, propose a cost model for evaluating the tradeoff between building a self-own computing platform and renting one from public provider. The cost evaluation formulas are derived based on some cost factor, such as human salary, platform purchasing cost, energy consuming, maintenance fee, and cooling cost, for evaluating required cost on building and operating of both public and private clouds. Based on the cost model, the authors applied a well-known public cloud instance, e.g. Chunghwa Telecom’s HiCloud platform in Taiwan, to compute renting cost, and make a comparison with the derived cost of private cloud for a variety of enterprises’ settings. According to the experiments, different size of enterprises could have different options in building private cloud or renting from public cloud to make optimum cost saving.

Resource provisioning is important issue in cloud computing and in the environment of heterogeneous clouds. The private cloud with confidentiality data configure according to users need. But the scalability of the private cloud limited. If the resources private clouds are busy in fulfilling other requests then new request cannot be fulfilled. The new requests are kept in waiting queue to process later. It take lot of delay to fulfill these requests and costly. In this paper Rule Based Resource Manager proposed for the Hybrid environment, which increase the scalability of private cloud on-demand and reduce the cost. Also set the time for public cloud and private cloud to fulfill the request and provide the services in time. The Evaluated the performance of Resource Manager on the basis of resource utilization and cost in hybrid cloud environment.

A case study of a U.S. manufacturer of motors and other mechanical drive systems illustrates a proposed reduction in capacity that utilizes the development and implementation of a cost model to determine the best alternatives for a company whose capacity is not synchronized with its business strategy. The cost model for each alternative is investigated and compared against the &lsquo;Do nothing&rsquo; alternative, using net present value and cash flow analysis to build a case for the most effective course of action. The findings show the benefits of merging manufacturing by separating people, non-people, and fixed costs by facility, product line and product. In addition, the paper also illustrates the benefits of modular manufacturing and outsourcing as a way to further improve costs after the reduction of capacity.<span style="mso-spacerun: yes;">&nbsp; </span></span></p>

Of late Multitenant model with In-Memory database has become prominent area for research. The paper has used advantages of multitenancy to reduce the cost for hardware, labor and make availability of storage by sharing database memory and file execution. The purpose of this paper is to give overview of proposed Supple architecture for implementing in-memory database backend and multitenancy, applicable in public and private cloud settings. Backend in-memory database uses column-oriented approach with dictionary based compression technique. We used dedicated sample benchmark for the workload processing and also adopt the SLA penalty model. In particular, we present two approximation algorithms, Multi-tenant placement (MTP) and Best-fit Greedy to show the quality of tenant placement. The experimental results show that Multi-tenant placement (MTP) algorithm is scalable and efficient in comparison with Best-fit Greedy Algorithm over proposed architecture.

Abstract. Within this work, an existing model of a Suzlon S111 2.1 MW turbine is used to estimate potential cost savings when the conventional upwind rotor concept is changed into a downwind rotor concept. A design framework is used to get realistic design updates for the upwind configuration, as well as two design updates for the downwind configuration, including a pure material cost out of the rotor blades and a new planform design. A full design load basis according to the standard has been used to evaluate the impact of the redesigns on the loads. A detailed cost model with load scaling is used to estimate the impact of the design changes on the turbine costs and the cost of energy. It is shown that generally lower blade mass of up to 5 % less than the upwind redesign can be achieved with the downwind configurations. Compared to an upwind baseline, the upwind redesign shows an estimated cost of energy reduction of 2.3 %, and the downwind designs achieve a maximum reduction of 1.3 %.

PurposeHybrid cloud composing of public and private cloud is seen as a solution for storage of health care data characterized by many private and sensitive data. In many hybrid cloud-based solutions, the data are perturbed and kept in public cloud, and the perturbation credentials are kept in private cloud.Design/methodology/approachHybrid cloud is a model combing private and public cloud. Security for the data is enforced using this distribution in hybrid clouds. However, these mechanisms are not efficient for range query and retrieval of data from cloud. In this work, a secure and efficient retrieval solution combining K-mean clustering, geometric perturbation and R-Tree indexing is proposed for hybrid clouds.FindingsCompared to existing solution, the proposed indexing on perturbed data is able to achieve 33% reduced retrieval time. The security of indexes as measured using variance of differences was 66% more than existing solutions.Originality/valueThis study is an attempt for efficient retrieval of data with range queries using R-Tree indexing approach.

Nowadays, a large number of groups choose to deploy their applications to cloud platforms, especially for the big data era. Currently, the hybrid cloud is one of the most popular computing paradigms for holding the privacy-aware applications driven by the requirements of privacy protection and cost saving. However, it is still a challenge to realize data placement considering both the energy consumption in private cloud and the cost for renting the public cloud services. In view of this challenge, a cost and energy aware data placement method, named CEDP, for privacy-aware applications over big data in hybrid cloud is proposed. Technically, formalized analysis of cost, access time, and energy consumption is conducted in the hybrid cloud environment. Then a corresponding data placement method is designed to accomplish the cost saving for renting the public cloud services and energy savings for task execution within the private cloud platforms. Experimental evaluations validate the efficiency and effectiveness of our proposed method.

Effective Assessment

In this paper, a generic comparison between the Enterprise Public and Private Cloud is analyzed based on its features and service provided. Cloud computing technology is widely adopted in today's industry where large database applications are deployed. Every organization moving towards cloud will have to consider many factors such as security, portability, database size, platform independence, multi-tenancy, customer requirements and other related resources. The detailed study focuses on essential cloud characteristics, service models, and cloud operation models such as Integrated (Hybrid), Public, Internal (Private) and Community clouds. The outcome is an effective assessment of leading two Enterprise cloud technology service providers – ownCloud© and HP Public Cloud® and its implications on the organizations which used them for cloud based applications. ownCloud© is the preferred open source file system for organizations to access for solutions across the world. HP Cloud offered by Hewlett-Packard (HP) provides public, private, hybrid and community cloud based services for various enterprise and other large-scale business organizations. Both the Private Cloud and Public Cloud can be enhanced to protect the data from intrusion with various security features where multiple users share the same cloud for storing and retrieving data
