A TQM PROCESS FOR SYSTEMS INTEGRATION Getting the Most from COTS Software

Many companies are shopping for commercial off-the-shelf software to avoid the high costs and lengthy development time associated with building their own systems. This article discusses how methods of total quality management (TQM) can be used to better integrate large-scale commercial software purchases.     

A TQM PROCESS FOR SYSTEMS INTEGRATION Getting the Most from COTS Software

Abstract

A few corporations and government agencies have begun applying artificial intelligence (AI) technology to business and logistical problems. If and when AI is incorporated into information processing systems, significant competitive opportunities may present themselves, but the return on an early AI investment can't be known yet. The six-stage model outlined in this article not only helps calculate the value of individual AI functions but also enables MIS management to anticipate AI's strategic potential.

Hierarchical aggregation of Service Level Agreements

IT-based Service Economy requires Service Markets to flourish for the trade of services. A market does not represent a simple buyer-seller relationship, rather it is the culmination point of a complex chain of stake-holders with a hierarchical integration of value along each point in the chain. To enable a Service Economy, Service Markets must be practically realized, which in turn requires an enabling infrastructure to support service value chains and service choreographies resulting from service composition scenarios. In such scenarios, services compose together hierarchically in a producer-consumer manner to form service supply-chains of added value. Service Level Agreements (SLAs) are defined at various levels in this hierarchy to ensure the expected quality of service for different stakeholders. Automation of service composition directly implies the aggregation of their corresponding SLAs.In this paper we elaborate on the requirements of hierarchical aggregation of SLAs corresponding to service choreographies leading to business models such as Business Value Networks. During the hierarchical aggregation of SLAs, certain SLA information pertaining to different stakeholders is meant to be restricted and can be only partially revealed to a subset of their business partners. We introduce the concept of SLA-Views to protect such privacy concerns. We then formalize the notion of SLA Choreography and define an aggregation model based on SLA-Views to enable the automation of hierarchical aggregation of Service Level Agreements. The aggregation model has been designed to comply with the WS-Agreement standard.

Getting on Board the Enterprise Service Bus

One of the biggest challenges facing businesses today is getting their diverse applications, often built on different platforms, to work together when necessary. To accomplish this, companies must implement effective application integration flexibly, quickly, and easily. Businesses initially turned to manual integration and then enterprise application integration (EAI) but subsequently have focused on service-oriented architectures. To leverage SOAs' benefits effectively, companies are beginning to use an approach known as the enterprise service bus, offered by a growing number of large and small vendors. ESB is the middleware glue that holds an SOA together and enables communication between Web-based enterprise applications. However, ESB also faces challenges, such as implementation costs and complex migration and management     

从安全的角度分析数据中心建设

作为基础网络资源的一部分,数据中心因为其高效性、规模效应、高处理性能等,得到目前各行业的广泛认可,数据中心的快速发展也为新的业务和模式的运行提供了可能性。但数据集中之后的信息安全问题也日益突显出来并更受到关注。本文将主要从网络的角度来分析数据中心的安全问题,按照威胁类型的不同分成4类,并对不同的安全威胁提出基于相应网络技术的解决方案,以此来加强数据中心的安全建设。     

With Service Level Agreements, Less is More

Service level agreements (SLAs) are formal negotiated agreements that enable IT organizations and their customers to collaboratively identify, discuss, and manage IT service expectations. Despite their potential, however, not all SLAs are successful. Based on experiences with numerous companies, the author argues that a tendency to “overcomplexify” is a major cause for SLA efforts to fail.     

Energy Efficient Cloud Service Provisioning: Keeping Data Center Granularity in Perspective

The cost of power and its associated delivery are becoming significant factors in the total expenditure of large-scale data centers. Numerous techniques have been proposed to address the energy efficiency issue in cloud systems. Recently, some efforts have been made to decentralize the cloud via distributing data centers in diverse geographical positions, at different scales. In this paper, we elaborate on the energy effectiveness of service provisioning on different cloud architectures, from a mega-data center to a nano data center, which provides the extreme decentralization in terms of cloud architecture, as well as P2P-clouds or community network clouds. We study the energy consumption through an analytical and simulation framework for video streaming and MapReduce applications.

Specification of Service Level Agreements: Problems, Principles and Practices

Software intensive systems (SIS) increasingly influence the ability of enterprises to be competitive in continuously changing market situations. The integration of these systems into organizations, and in particular the subsequent exploitation, maintenance and service activities, have become of utmost importance. Unfortunately the area of exploitation and operation, also known as service management, is still rather immature. Service management covers services such as performance and availability support, end-user and help desk support, education, and maintenance. One of the main concepts of service management is the Service Level Agreement (SLA). The goal of an SLA is to bridge the gap between service provider and users or customers. However, there exist many problems and unsolved questions regarding the specification and the quantification of SLAs. This paper addresses the specification of SLAs on the basis of three well-founded service management principles, respectively: 'continuity in service management, the pit/shell principle of a service, and the principle of specifying the quality of both a service process and a service object. Finally, the paper addresses the validation of these principles in practice.
