Application Service Provider
An application service provider (ASP) is a business providing application software generally through the. ASPs that specialize in a particular application (such as a medical billing program) may be referred to as providing software as a service. The ASP model The application software resides on the vendor's system and is accessed by users through a communication protocol. Alternatively, the vendor may provide special purpose client software. Client software may interface with these systems through an application programming interface. ASP characteristics include: * ASP hosts the application * ASP owns, operates and maintains the servers that support the application * ASP delivers the application to customers via the Internet or a thin client * ASP may bill on a per-use basis ( on-demand outsourcing), a monthly/annual fee, or a per-labor hour basis The advantages to this approach include: * Application costs are scaled over multiple customers * ASP may provide more application ex ...

Application Software
Application software is any computer program that is intended for end-user use not operating, administering or programming the computer. An application (app, application program, software application) is any program that can be categorized as application software. Common types of applications include word processor, media player and accounting software. The term ''application software'' refers to all applications collectively and can be used to differentiate from system and utility software. Applications may be bundled with the computer and its system software or published separately. Applications may be proprietary or open-source. The short term ''app'' (coined in 1981 or earlier) became popular with the 2008 introduction of the iOS App Store, to refer to applications for mobile devices such as smartphones and tablets. Later, with introduction of the Mac App Store (in 2010) and Windows Store (in 2011), the term was extended in popular use to include desktop a ...

Business Service Provider
A business service provider is one of several categories of service provider in the business world. As opposed to an application service provider which provides application components over a computer network, the services provided by a business service provider are more in the area of infrastructure: mail delivery, building security, finance, administration, and human services. Types of business service providers Back Office The back office operations are the off-site delivery of a range of non-core service functions, including routine administration tasks and technical support. Offshore back office operations involve the ongoing use of an outsourcing base in another country. Front Office The front office is the part of a company that comes in contact with clients, such as the marketing, sales, and customer service Customer service is the assistance and advice provided by a company to those who buy or use its products or services, either in person or remotely.

Web Application
A web application (or web app) is application software that is created with web technologies and runs via a web browser. Web applications emerged during the late 1990s and allowed for the server to dynamically build a response to the request, in contrast to static web pages. Web applications are commonly distributed via a web server. There are several different tier systems that web applications use to communicate between the web browsers, the client interface, and server data. Each system has its own uses as they function in different ways. However, there are many security risks that developers must be aware of during development; proper measures to protect user data are vital. Web applications are often constructed with the use of a web application framework. Single-page applications (SPAs) and progressive web apps (PWAs) are two architectural approaches to creating web applications that provide a user experience similar to native apps, including features such as smoo ...

Utility Computing
Utility computing, or computer utility, is a service provisioning model in which a service provider makes computing resources and infrastructure management available to the customer as needed, and charges them for specific usage rather than a flat rate. Like other types of on-demand computing (such as grid computing), the utility model seeks to maximize the efficient use of resources and/or minimize associated costs. Utility is the packaging of system resources, such as computation, storage and services, as a metered service. This model has the advantage of a low or no initial cost to acquire computer resources; instead, resources are essentially rented. This repackaging of computing services became the foundation of the shift to "on demand" computing, software as a service and cloud computing models that further propagated the idea of computing, application and network as a service. There was some initial skepticism about such a significant shift. However, the new model of com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Service Level Agreement
A service-level agreement (SLA) is an agreement between a service provider and a customer. Particular aspects of the service – quality, availability, responsibilities – are agreed between the service provider and the service user. The most common component of an SLA is that the services should be provided to the customer as agreed upon in the contract. As an example, Internet service providers and telcos will commonly include service level agreements within the terms of their contracts with customers to define the level(s) of service being sold in plain language terms. In this case, the SLA will typically have a technical definition of '' mean time between failures'' (MTBF), '' mean time to repair'' or '' mean time to recovery'' (MTTR); identifying which party is responsible for reporting faults or paying fees; responsibility for various data rates; throughput; jitter; or similar measurable details.

Outsourcing
Outsourcing is a business practice in which companies use external providers to carry out business processes that would otherwise be handled internally. Outsourcing sometimes involves transferring employees and assets from one firm to another. The term ''outsourcing'', which came from the phrase ''outside resourcing'', originated no later than 1981 at a time when industrial jobs in the United States were being moved overseas, contributing to the economic and cultural collapse of small, industrial towns. In some contexts, the term smartsourcing is also used. The concept, which ''The Economist'' says has "made its presence felt since the time of the Second World War", often involves the contracting out of a business process (e.g., payroll processing, claims processing), operational, and/or non-core functions, such as manufacturing, facility management, call center/call center support. The practice of handing over control of public services to private enterprises ( privatiz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multitenancy
Software multitenancy is a software architecture in which a single instance of software runs on a server and serves multiple tenants. Systems designed in such manner are "shared" (rather than "dedicated" or "isolated"). A tenant is a group of users who share a common access with specific privileges to the software instance. With a multitenant architecture, a software application is designed to provide every tenant a dedicated share of the instance—including its data, configuration, user management, tenant individual functionality and non-functional properties. Multitenancy contrasts with multi-instance architectures, where separate software instances operate on behalf of different tenants. Some commentators regard multitenancy as an important feature of cloud computing. Adoption History of multitenant applications Multitenant applications have evolved from—and combine some characteristics of—three types of services: # Timesharing: From the 1960s companies rented spac ...

Hosted Service Provider
A hosted service provider (xSP) is a business that delivers a combination of traditional IT functions such as infrastructure, applications (software as a service), security, monitoring, storage, web development, website hosting and email, over the Internet or other wide area networks (WAN). An xSP combines the abilities of an application service provider (ASP) and an Internet service provider (ISP). This approach enables customers to consolidate and outsource much of their IT needs for a predictable recurring fee. xSPs that integrate web publishing give customers a central repository to rapidly and efficiently distribute information and resources among employees, customers, partners and the general public. Hosted Service Providers benefit from economies of scale and operate on a one-to-many business model, delivering the same software and services to many customers at once. Customers are charged on a subscription basis. Services offered As defined by analyst Ovum. * Repeatable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Communication As A Service
Cloud computing is "a paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on-demand," according to ISO. Essential characteristics In 2011, the National Institute of Standards and Technology (NIST) identified five "essential characteristics" for cloud systems. Below are the exact definitions according to NIST: * On-demand self-service: "A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider." * Broad network access: "Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations)." * Resource pooling: " The provider's computing resources are pooled to serve multiple consumers using a multi-ten ...

Application Server
An application server is a server that hosts applications or software that delivers a business application through a communication protocol. For a typical web application, the application server sits behind the web servers. An application server framework is a service layer model. It includes software components available to a software developer through an application programming interface. An application server may have features such as clustering, fail-over, and load-balancing. The goal is for developers to focus on the business logic. Java application servers Jakarta EE (formerly Java EE or J2EE) defines the core set of API and features of Java application servers. The Jakarta EE infrastructure is partitioned into logical containers. *EJB container: Enterprise Beans are used to manage transactions. According to the Java BluePrints, the business logic of an application resides in Enterprise Beans—a modular server component providing many features, including dec ...

Http
HTTP (Hypertext Transfer Protocol) is an application layer protocol in the Internet protocol suite model for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources that the user can easily access, for example by a Computer mouse, mouse click or by tapping the screen in a web browser. Development of HTTP was initiated by Tim Berners-Lee at CERN in 1989 and summarized in a simple document describing the behavior of a client and a server using the first HTTP version, named 0.9. That version was subsequently developed, eventually becoming the public 1.0. Development of early HTTP Requests for Comments (RFCs) started a few years later in a coordinated effort by the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C), with work later moving to the IETF. HTTP/1 was finalized and fully documented (as version 1.0) in 1996 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
On-demand Outsourcing
On-demand outsourcing is a trend in outsourcing wherein major internal operations processes of a company are being shifted to a provider that is paid for by the number of transactions involved. The business transferring the services pays for the quality, special skills and the competence of the service provider's employees. There has been an expansion of the outsourcing concept to include on-demand outsourcing. This refers to the process undertaken by business managers to adopt an outsourcing policy that ensures that the specific business and supplies including technical manpower are accessed as the need arises. It focuses a business strategy to improve its goods and services and to drive a business towards quality improvement. Background The reasons for general outsourcing can be summarized in following factors: the rising wages of the domestic worker, or companies wish to gain access to the exceptional capability. The risk of outsourcing service is normally assumed by the outsour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
