    Monitoring solutions for virtualizedinfrastructure (VI) should evolve to collect, analyze andprovide configuration recommendation based on a broaderrange of operational metrics. A virtualized infrastructureis a complex interaction of hardware (servers, network andstorage), hosting variety of multi-tier application with specificservice level requirements and governed by their security andcompliance policies. Most existing solutions of today monitorand analyze only a subset of these interactions. The analysis andrecommendation obtained tend to optimize only particular aspectsof the infrastructure and can potentially introduce violations forthe others. A virtualized infrastructure is dynamic in nature,providing immense opportunities to automate configurationchanges to virtual machines, networks and storage. It deliversthe capability to administer the whole of infrastructure as a largeresource pool shared by multiple workloads. Monitoring solutionsthat look at only few aspects end up forcing administrators tocreate silos within the infrastructure that are specially designedto ensure that business service requirements are met for thespecific applications running there. A monitoring solution thatcan collect and analyze multiple aspects for assisting in decisionmaking and process automation can deliver greater efficiency tothe virtualized infrastructure.In this paper we argue the importance of having amonitoring solution that provides a holistic view of thevirtualized infrastructure. We discuss the need for solutions tobe capable of monitoring and analyzing a broader set of metricssuch as health of infrastructure components; performance ofoperating environment such as hypervisors, operating systemsand application running on them; capacity utilization indicatorsfor server, networks and storages; information available withconfiguration and change management database containingpolicies including security and compliance policies. We also takea look at what these broader set of metrics are and who wouldbe interested in them. The paper further proposes a monitoringframework for collecting and analyzing the above mentionedaspects of a virtual infrastructure to develop a more completesolution

    Cost Driver Based Internal IT Cost Allocation: A Case of a Medium-Sized Austrian Financial Service Provider

    Get PDF
    IT has a high share of the total costs at information processing companies. Though not only minimal IT costs are relevant, but also effective use of IT from the long term business perspective. Decisions on IT investments are made based on information about costs and benefits commonly provided by controlling in-struments. To identify direct and indirect costs of IT services, an internal IT cost allocation (IT activity allocation or IT chargeback) is being used by the vast ma-jority of companies, especially in IT-related industries. The allocation of shared IT infrastructures and overhead costs to IT services, as well as of IT services to service recipients, is based on simplified allocation keys. Allocation keys are commonly built use-based, per revenue share or per employee. For example allo-cation per CPU or RAM for servers and per Gigabyte of disk space for central storage systems is commonly being used. Nowadays those rarely are relevant cost drivers, except for extreme increases in usage intensity, which raise jump-fixed costs to a higher level. As a consequence service recipients lack the possi-bility and incentive to control the real costs and to optimize the cost/benefit ratio. Furthermore allocated costs, especially for shared services, do not represent cor-rectly the real cost situation and product pricing and business cases based on those costs are not accurate. As a constraint information cost to gain data to build allocation keys have be reasonable. The question is, how to build allocation keys as accurate as possible to apportion ‘real’ IT costs with reasonable effort. The pa-per at hand describes the internal IT cost allocation and its allocation keys based on main actual cost drivers by means of a case study at a typical medium-sized Austrian financial service provider. This approach yields a more accurate alloca-tion of actual IT costs

    Data centers are continuously expanding, so does the energy consumed to power their infrastructure. Server is the major component of data center’s computer rooms, which runs the most intensive computational workloads and stores the data. Server is responsible for more than a quarter of the total energy consumption of data center. This thesis is focused on analyzing and predicting the energy consumption of the server. Three major components are considered in our study; the processor, the access memory and the network interface controller. We collect data from these components and analyze them using linear regression Lasso model with non-negative coefficients. A power model is proposed for predicting energy consumption at the system-level. The model takes as input CPU cycles and data Translation Lookaside Buffer loads, and predicts the energy consumption of the server with 5.33% median error regardless of its workload

    Cross-border e-commerce becomes more and more popular and general. The foci of researches in e-commerce have moved from domestic towards to global market. Yet, most of extant literatures are from buyer’s perspective, whereas sellers are also important in the success of cross-border e-commerce. In this study, we are aiming to identify the elements of the success of cross-border e-commerce and the relationship with trust and intention to use from seller’s perspective. To do so, we apply a mixed method to accomplish this research. We have identified the key factors which sellers are concerned about, and why they engage in cross-border e-commerce. In addition, we have developed new dimensions with associated items for system quality, service quality, perceived benefit and perceived cost in the context of cross-border e-commerce. The theoretical contributions and practical contributions have been discussed lastly

    There\u27s an App for That: Developing Online Dispute Resolution to Empower Economic Development

    Traditionally, litigation has been the norm for resolving disputes. It takes place in a public forum and face-to-face. In a global economy, however, such public and face-to-face dispute resolution is not feasible. This is especially true with cross-border purchases through e-commerce. E-commerce requires more efficient and less litigious remedy systems that allow consumers to obtain remedies on their purchases without the cost and travel associated with traditional face-to-face procedures. This has led to development of online dispute resolution (“ODR”) processes, especially with respect to business-to-consumer contracts. Accordingly, scholarship and policy papers have advanced ODR for the benefit of consumers. What deserves emphasis, however, is promotion of ODR to empower businesses that seek to attract customers globally. Establishment of trusted ODR systems incentivizes consumers to make cross-border purchases because it provides them with the comfort of knowing there is a cheap and easy means for obtaining a remedy if the purchase goes awry. This is especially important to assist businesses in developing nations, where Internet access is expanding through use of smartphones and similar mobile devices. Such mobile access is narrowing the so-called “digital divide” and fostering enthusiasm for building e-commerce, which is imperative for economic development and global integration. ODR can further these efforts by catalyzing consumer trust, and consequently cross-border sales. This article, therefore, encourages growth of global ODR that is accessible through mobile devices as means for increasing access to remedies and trustworthy e-commerce for companies and consumers in developing nations
