The Garch Model

Cloud Computing offers significant cost benefits for SMEs that often do not manage internal IT infrastructure and start-up companies that do not have their own IT infrastructure. This paper presents a total cost of ownership (TCO) approach for cloud computing services with an emphasis on the infrastructure as a service (IaaS) model. Also, the paper presents a methodology for estimating total cost of ownership (TCO) when running computer instances in the IaaS cloud using the GARCH model to predict transaction volatility. The research results show that it is possible to successfully use GARCH models when there is historical data on the number of transactions. In addition, simulation shows that, when there are large oscillations in the number of transactions, the best choice is to reserve instances according to the Partial-Upfront price model. In contrast, if the transaction number is relatively stable, the best choice is the All-Upfront model.

This paper consists of four major sections: The first section is a literature review of cloud computing and a cost model. The next section focuses on detailed overviews of cloud computing and its levels of services: SaaS, PaaS, and IaaS. Major cloud computing providers are introduced, including Amazon Web Services (AWS),<br />Microsoft Azure, and Google App Engine. Finally, case studies of implementing web applications on IaaS and PaaS using AWS, Linode and Google AppEngine are demonstrated. Justifications of running on an IaaS provider (AWS) and running on a PaaS provider (Google AppEngine) are described. The last section discusses costs and technology analysis comparing cloud computing with local managed storage and servers. The total costs of ownership (TCO) of an AWS small instance are significantly<br />lower, but the TCO of a typical 10TB space in Amazon S3 are<br />significantly higher. Since Amazon offers lower storage pricing for huge amounts of data, the TCO might be lower. Readers should do their own analysis on the TCOs.

Cloud computing services are nowadays advertised as an emerging business model. Moreover, these services bring innovative solutions in a more sophisticated competitive market. But, the decision for their adoption could be significantly reduced due to organizations’ concerns related to security, privacy, and trust. The challenge involves such questions as where to start, which provider should the company choose or whether it is even worthwhile. Thus, this paper proposes an improved unified framework, based on a previous study where a 6 step process framework was introduced. This improved framework add one new step for security and control after the migration process. At the end, a 7 processes framework is proposed aimed to fulfill organizations’ concerns when decide to adopt cloud computing services with a follow-up step. This additional step intends to help IT directors to make sure everything is working properly in a methodological way, in order to achieve a successful cloud computing migration process. An effective solution that is gaining momentum and popularity for competitive organizations.

Structured abstract Rendering digital services have taken centerstage in the current ICT for development discourse. E-Government services are mostly under this discourse with the aim to provide citizen centric services in the public domain. Business and development organizations alike are also investing in developing their own digital infrastructure for rendering services to its stakeholders. This case describes scenario in which a cooperative organization wishes to use digital infrastructure and provide digital services to its farmer members. The cooperative continued investing in ICT since the last couple of decades and constantly upgraded it to ease the transaction and bring efficiency and reduce information asymmetry. This had greatly benefitted the members. However, the cooperative is aware that its communication network built on the wireless medium has its own limitations in introducing new services and integrating its databases and applications. The cooperative took note of “Digital India (DI)” initiatives to provide digital services to rural areas and build an ecosystem to empower the citizens in its governance set up. This DI policy has implicit provisions of better networking protocols with improved bandwidth. The organization has a dilemma to continue with investing its own resources or explore possibility of piggybacking on the DI initiative. The cooperative wished to examine the total cost of ownership in either case and assess the feasibility of converging with the infrastructure created by the government. Case synopsis The Government Information Technology Policies are increasingly favouring citizens and in favour of shared infrastructure and services. It is worth the examination to evaluate strategies to deploy IT infrastructure and services with optimized cost and better returns in an enterprise. This is far more important for a social enterprise like AMALSAD cooperative (user-owned firm) that has deployed its own IT infrastructure and ITeS. AMALSAD cooperative deployed its IT assets long back and in the meanwhile, the Government policy is in favour of providing services over the internet. Leaning objectives The case serves to help students to understand the theoretical concept of Enterprise information systems infrastructure and services. It brings to the students understanding: the drivers of IT infrastructure to provide digital services; challenges that would make the social enterprise (in this case user-owned firm) to understand the opportunities and challenges of deploying the right digital infrastructure and get services on demand. The case presents the scenarios for the students to deliberate and find answers to the right approach for estimating the total cost of ownership (TCO). Social implications The case situation presents a scenario for digital government services. Most of the customer-facing enterprises including social enterprises are also providing digital services. It is important that such services converge at an optimized TCO. Complexity academic level Masters in Business Administration with a concentration in Information Systems.

Cloud computing is a technique for supplying computer facilities and providing access to software via the Internet.  Cloud computing represents a contextual shift in how computers are provisioned and accessed.  One of the defining characteristics of cloud software service is the transfer of control from the client domain to the service provider.  Another is that the client benefits from economy of scale on the part of the provider.  Cloud computing is particularly attractive to small and medium-sized educational institutions, because it represents a lower total cost of ownership (TCO) than alternative modalities.

Cloud Computing Services

Cloud computing is a type of computing where computing services such as applications, storage, infrastructure, processing power are hosted by some vendors (cloud vendors) over the Internet and delivered to users on on-demand basis. A company can benefit from cloud computing in the sense that they can rent access to anything from applications to storage to processing power rather than owning their own IT infrastructure. By using cloud-computing services, companies can avoid the various costs and complexities associated with owning and maintaining their own IT infrastructure as everything is taken care of by the service providers. Cloud computing is a paradigm in which both the users and the service providers are benefited. Service providers are greatly benefited from cloud computing by providing cloud services to a wide range of customers. The primary objective of this paper is to give an overview on cloud computing encompassing its features, the pros and cons of cloud computing and the challenges that comes with it. Furthermore, this paper also presents a list of security concerns in cloud computing which stands in the way of wide spread adoption of cloud computing thereby motivating researchers to devise competent solutions to tackle these ongoing security issues.
