WS-Policy4MASC
WS-Policy4MASC is a policy language for managing Web services and their composition. Overview WS-Policy4MASC extends a widely used industrial standard, WS-Policy, with information necessary for run-time management, including the unique support for autonomic business-driven IT management (BDIM). The specifications of diverse financial and non-financial business value metrics and business strategies that guide business-value driven selection among alternative control (adaptation) actions are the main distinctive characteristics and contributions of WS-Policy4MASC. WS-Policy4MASC also supports other management aspects, such as fault management and maximization of technical QoS metrics. It has built-in constructs for specification of a wide range of adaptations and events common in management of service-oriented systems and business process A business process, business method, or business function is a collection of related, structured activities or tasks performed by people or ...

WS-Policy
WS-Policy is a specification that allows web services to use XML to advertise their policies (on security, quality of service, etc.) and for web service consumers to specify their policy requirements. WS-Policy is a W3C recommendation as of September 2007. WS-Policy represents a set of specifications that describe the capabilities and constraints of the security (and other business) policies on intermediaries and end points (for example, required security tokens, supported encryption algorithms, and privacy rules) and how to associate policies with services and end points. Policy Assertion Assertions can either be requirements put upon a web service or an advertisement for the policies of a web service. Operator tags Two "operators" (XML tags) are used to make statements about policy combinations: *''wsp:ExactlyOne'' - asserts that only one child node must be satisfied. *''wsp:All'' - asserts that all child nodes must be satisfied. Logically, an empty ''wsp:All'' tag makes no ass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Service
A web service (WS) is either: * a service offered by an electronic device to another electronic device, communicating with each other via the Internet, or * a server running on a computer device, listening for requests at a particular port over a network, serving web documents (HTML, JSON, XML, images). In a web service, a web technology such as HTTP is used for transferring machine-readable file formats such as XML and JSON. In practice, a web service commonly provides an object-oriented web-based interface to a database server, utilized for example by another web server, or by a mobile app, that provides a user interface to the end-user. Many organizations that provide data in formatted HTML pages will also provide that data on their server as XML or JSON, often through a Web service to allow syndication. Another application offered to the end-user may be a mashup, where a Web server consumes several Web services at different machines and compiles the content into one user int ...

Information Technology Management
Information technology management (IT management) is the discipline whereby all of the information technology resources of a firm are managed in accordance with its needs and priorities. Managing the responsibility within a company entails many of the basic management functions, like budgeting, staffing, change management, and organizing and controlling, along with other aspects that are unique to technology, like software design, network planning, tech support etc. Purpose The central aim of IT management is to generate value through the use of technology. To achieve this, business strategy, business strategies and technology must be aligned. IT Management is different from management information systems. The latter refers to management methods tied to the automation or support of human decision making. IT Management refers to IT related management activities in organizations. MIS is focused mainly on the business aspect, with a strong input into the technology phase of the bus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Business Value
In management, business value is an informal term that includes all forms of Value (economics), value that determine the health and well-being of the firm in the long run. Business value expands concept of value of the firm beyond economic value (also known as economic profit, economic value added, and shareholder value) to include other forms of value such as employee value, customer value, supplier value, channel partner value, alliance partner value, managerial value, and societal value. Many of these forms of value are not directly measured in monetary terms. According to the Project Management Institute, business value is the "net quantifiable benefit derived from a business endeavor that may be tangible, intangible, or both." Business value often embraces intangible assets not necessarily attributable to any Stakeholder (corporate), stakeholder group. Examples include intellectual capital and a firm's business model. The balanced scorecard methodology is one of the most popula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fault Management
In network management, fault management is the set of functions that detect, isolate, and correct malfunctions in a telecommunications network, compensate for environmental changes, and include maintaining and examining error logs, accepting and acting on error detection notifications, tracing and identifying faults, carrying out sequences of diagnostics tests, correcting faults, reporting error conditions, and localizing and tracing faults by examining and manipulating database information. When a fault or event occurs, a network component will often send a notification to the network operator using a protocol such as SNMP. An alarm is a persistent indication of a fault that clears only when the triggering condition has been resolved. A current list of problems occurring on the network component is often kept in the form of an active alarm list such as is defined in RFC 3877, the Alarm MIB. A list of cleared faults is also maintained by most network management systems. Fault m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Service-orientation
Service-orientation is a design paradigm for computer software in the form of Service (Systems Architecture), services. The principles of service-oriented design stress the separation of concerns in the software. Applying service-orientation results in units of software partitioned into discrete, autonomous, and network-accessible units, each designed to solve an individual concern. These units qualify as services. History of service-orientation principles and tenets Service-orientation has received a lot of attention since 2003 due to the benefits it promises. These include increased return on investment, organisational agility and interoperability as well as a better alignment between business and Information technology, IT. It builds heavily on earlier design paradigms and enhances them with standardisation, loose coupling and business involvement. The paradigm lost momentum in 2009; since 2014, renewed interest can be observed under the Microservices moniker. In technology, dif ...

Business Process
A business process, business method, or business function is a collection of related, structured activities or tasks performed by people or equipment in which a specific sequence produces a service or product (that serves a particular business goal) for a particular customer or customers. Business processes occur at all organizational levels and may or may not be visible to the customers. A business process may often be visualized (modeled) as a flowchart of a sequence of activities with interleaving decision points or as a process matrix of a sequence of activities with relevance rules based on data in the process. The benefits of using business processes include improved customer satisfaction and improved agility for reacting to rapid market change. Process-oriented organizations break down the barriers of structural departments and try to avoid functional silos. Overview A business process begins with a mission objective (an external event) and ends with achievement of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
