Service-oriented Infrastructure
Service Oriented Infrastructure or SOI provides a system for describing information technology (IT) infrastructure as a service. The underlying principles go back to, among others, Mainframe and LDAP technologies; SOI provides a framework or mindset for making business benefits measurable. Overview A service-oriented infrastructure provides a foundation for IT services. A concept initially developed by Intel discussed three domains for service-orientation: # the enterprise # the application architecture # the infrastructure This article covers the infrastructure domain of service-orientation. Key aspects of service-oriented infrastructure include industrialisation and virtualisation, providing IT infrastructure services via a pool of resources (web servers, application servers, database servers, servers, storage instances) instead of through discrete instances. While the IT industry has widely adopted service-oriented architecture (SOA), service-oriented infrastructure or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Information Technology
Information technology (IT) is the use of computers to create, process, store, retrieve, and exchange all kinds of data . and information. IT forms part of information and communications technology (ICT). An information technology system (IT system) is generally an information system, a communications system, or, more specifically speaking, a computer system — including all hardware, software, and peripheral equipment — operated by a limited group of IT users. Although humans have been storing, retrieving, manipulating, and communicating information since the earliest writing systems were developed, the term ''information technology'' in its modern sense first appeared in a 1958 article published in the ''Harvard Business Review''; authors Harold J. Leavitt and Thomas L. Whisler commented that "the new technology does not yet have a single established name. We shall call it information technology (IT)." Their definition consists of three categories: techniques for pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storage Virtualization
In computer science, storage virtualization is "the process of presenting a logical view of the physical storage resources to" a host computer system, "treating all storage media (hard disk, optical disk, tape, etc.) in the enterprise as a single pool of storage." A "storage system" is also known as a storage array, disk array, or ''filer''. Storage systems typically use special hardware and software along with disk drives in order to provide very fast and reliable storage for computing and data processing. Storage systems are complex, and may be thought of as a special purpose computer designed to provide storage capacity along with advanced data protection features. Disk drives are only one element within a storage system, along with hardware and special purpose embedded software within the system. Storage systems can provide either block accessed storage, or file accessed storage. Block access is typically delivered over Fibre Channel, iSCSI, SAS, FICON or other protocol ...

Grid Computing
Grid computing is the use of widely distributed computer resources to reach a common goal. A computing grid can be thought of as a distributed system with non-interactive workloads that involve many files. Grid computing is distinguished from conventional high-performance computing systems such as cluster computing in that grid computers have each node set to perform a different task/application. Grid computers also tend to be more heterogeneous and geographically dispersed (thus not physically coupled) than cluster computers. Although a single grid can be dedicated to a particular application, commonly a grid is used for a variety of purposes. Grids are often constructed with general-purpose grid middleware software libraries. Grid sizes can be quite large. Grids are a form of distributed computing composed of many networked loosely coupled computers acting together to perform large tasks. For certain applications, distributed or grid computing can be seen as a special type of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Service Oriented Architecture
In software engineering, service-oriented architecture (SOA) is an architectural style that focuses on discrete services instead of a monolithic design. By consequence, it is also applied in the field of software design where services are provided to the other components by application components, through a communication protocol over a network. A service is a discrete unit of functionality that can be accessed remotely and acted upon and updated independently, such as retrieving a credit card statement online. SOA is also intended to be independent of vendors, products and technologies. Service orientation is a way of thinking in terms of services and service-based development and the outcomes of services. A service has four properties according to one of many definitions of SOA: # It logically represents a repeatable business activity with a specified outcome. # It is self-contained. # It is a black box for its consumers, meaning the consumer does not have to be aware of the se ...

Total Cost Of Ownership
Total cost of ownership (TCO) is a financial estimate intended to help buyers and owners determine the direct and indirect costs of a product or service. It is a management accounting concept that can be used in full cost accounting or even ecological economics where it includes social costs. For manufacturing, as TCO is typically compared with doing business overseas, it goes beyond the initial manufacturing cycle time and cost to make parts. TCO includes a variety of cost of doing business items, for example, ship and re-ship, and opportunity costs, while it also considers incentives developed for an alternative approach. Incentives and other variables include tax credits, common language, expedited delivery, and customer-oriented supplier visits. Use of concept TCO, when incorporated in any financial benefit analysis, provides a cost basis for determining the total economic value of an investment. Examples include: return on investment, internal rate of return, economic value ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SOI Service
''Soi'' ( th, ซอย ) is the term used in Thailand for a side-street branching off a major street (''thanon'', th, ถนน). An alley is called a ''trok'' ( th, ตรอก). Overview Sois are usually numbered, and are referred to by the name of the major street and the number, as in "Soi Sukhumvit 4", "Sukhumvit Soi 4", or "Sukhumvit 4", all referring to the fourth soi of Sukhumvit Road in Bangkok. When walking on the major street towards increasing soi numbers, all the even-numbered sois are on the right side and the odd-numbered ones on the left side of the street. If for instance a new soi is added between soi 7 and soi 9 it will get the number soi 7/1, the next one soi 7/2, etc. It is also possible that soi 20 is far away from soi 21 if there are more sois on one side of the street than on the other. While sois are commonly referred to by number, almost all sois in Bangkok also have a name. On lower Sukhumvit road in Bangkok, for instance, the sois are named after i ...
