IT Service and website development

IT as a Service (ITaaS) is a technology-delivery method that treats IT (information technology) as a commodity, providing an enterprise with exactly the amount of hardware, software, and support that it needs for an agreed-on monthly fee. In this context, IT encompasses all of the technologies for creating, storing, exchanging, and using business data.

According to its proponents, ITaaS has numerous and diverse benefits including:

 * Minimal upfront IT investment
 * Regular, predictable expenses
 * Financial transparency
 * Tax advantages
 * Continuous monitoring of services
 * Expert technical support
 * Scalability
 * Regular software upgrades and patches
 * Guarantee of up-to-date hardware

information technology (IT)
information technology (IT) a general term applied to all computer-based technologies of human communication. It can be viewed as a broad sub-type of NEW TECHNOLOGY. Office automation is the most widely implemented form of information technology and has had major implications for the organization and experience of clerical work. This development has stimulated much sociological research and commentary on the issues of DESKILLING and PROLETARIANIZATION as well as the feminization of clerical work (Crompton and Jones, 1984; Webster, 1996). Information technology underpins the flow of information (i.e. information systems) within and between organizations and societies giving rise to increasing dependency on global networks including the Internet (CASTELLS, 1996). The increasing reliance on computer-based information systems has also given rise to concerns over the electronic power of the state (Lyons, 1988) and the possibility that information technology turns work organizations into the new panopticans in which everyone is under continual surveillance and control, an interpretation that draws directly on the work of FOUCAULT.

Information technology can be said to have begun in 1943, with the building of the Colossus computing machine in the UK in order to break the German Enigma code. By the late 1950s computers had been introduced into the major British banks, and were being used within accounts departments a little later (Mumford and Banks, 1967). At this point, the technology was limited to routine activities, involving the computation of data rather than the communication of information. However, with the development of more powerful interactive (i.e. ‘real time’ computer systems), and of smaller computers (minis and micros) coupled with ‘off the shelf programs (generally known as ‘software packages’), information technology has spread throughout industry, and has now extended into people's homes and leisure activity. The main development in information technology in recent years has been the digital integration of information and telecommunications technologies, such as fax machines and electronic mail and currently between cell phones and ‘palm top’ computers. The divide between information and communication technologies has now been virtually eroded; they are now common technologies of communication.

What is website development?
Website development refers to the work that goes into building a website. This could apply to anything from creating a single plain-text webpage to developing a complex web application or social network.

While web development typically refers to web markup and coding, it includes all related development tasks, such as client-side scripting, server-side scripting, server and network security configuration, ecommerce development, and content management system (CMS) development.

Why is web development important?
You might be a business owner hiring a freelance developer to build your website, a marketer pitching a vision to your development team, or a student learning about development as a career. Regardless of who you are or why you’re reading this guide, understanding the basics of website development can be helpful in this technology-driven world.

The internet isn’t going away anytime soon. In fact, it’s become a portal and primary method of research, connection, education, and entertainment in the world. As of 2019, there are 4.2 billion global internet users. That’s more than half the world’s population, and these folks are using the internet for a vast variety of reasons.

What’s the one thing those reasons have in common? They require a website, and each website requires a skilled web developer.

Web development is also a rapidly expanding industry. Between now and 2028, the employment of web developers is expected to grow by 13%. That’s much faster than most other technology careers.

The field of engineering
The field of engineering involving computer-based hardware and software systems, and communication systems, to enable the acquisition, representation, storage, transmission, and use of information. Successful implementation of information technology (IT) is dependent upon being able to cope with the overall architecture of systems, their interfaces with humans and organizations, and their relationships with external environments. It is also critically dependent on the ability to successfully convert information into knowledge.

Information technology is concerned with improvements in a variety of human and organizational problem-solving endeavors through the design, development, and use of technologically based systems and processes that enhance the efficiency and effectiveness of information in a variety of strategic, tactical, and operational situations. Ideally, this is accomplished through critical attention to the information needs of humans in problem-solving tasks and in the provision of technological aids, including electronic communication and computer-based systems of hardware and software and associated processes. Information technology complements and enhances traditional engineering through emphasis on the information basis for engineering.

The knowledge and skills required in information technology
The knowledge and skills required in information technology come from the applied engineering sciences, especially information, computer, and systems engineering sciences, and from professional practice. Professional activities in information technology and in the acquisition of information technology systems range from requirements definition or specification, to conceptual and functional design and development of communication and computer-based systems for information support. They are concerned with such topics as architectural definition and evaluation. These activities include integration of new systems into functionally operational existing systems and maintenance of the result as user needs change over time. This human interaction with systems and processes, and the associated information processing activities, may take several diverse forms. See engineering, Systems architecture, Systems engineering

The hardware and software of computing and communications form the basic tools for information technology. These are implemented as information technology systems through use of systems engineering processes. While information technology and information systems engineering does indeed enable better designs of systems and existing organizations, it also enables the design of fundamentally new organizations and systems such as virtual corporations. Thus, efforts in this area include not only interactivity in working with clients to satisfy present needs but also awareness of future technological, organizational, and human concerns so as to support transition over time to new information technology-based services.
