This segment of the market for it outsourcing is actively growing in the Russian market, despite increasing competition, largely that risk depending on the customer's company from a service provider in this case is minimal, as a fairly standard set of services. At the same time, the market segment of it outsourcing services offered to larger organizations in addition to basic services should include a range of services and support hardware operated large-scale business systems. Outsourcing the support of it hardware infrastructure is usually in demand it service, which itself must be sufficiently well developed to provide a full cycle of development and operation of business-critical information systems. Moreover, apart from the hardware necessary to support the applications that enhance the functionality of systems that interact with the business divisions of the company. These functions are most noticeable for the "internal customers" of it services, and that their performance determines the overall perception of service quality. Customary to distinguish the following components of it outsourcing: – support services users (Desktop Services, Help Desk Services); – asset management (Asset Management Services); – support services for business continuity (Business Continuity Services); – Services data centers (Data Center Services, Storage Services); – Management Services Network (Managed and Professional Network Services, Networking and Communications Services); – Management Services security (Security Management Services); – Outsourcing of applications (Applications Outsourcing): – support services for ERP-and CRM-systems – application hosting (ASP); – database support – marketing and sales.

Often, the company bought consulting services from it companies. Data services are in demand where large price errors that require the original or quickly implemented solutions. At the heart of the relationship with the customer, an it consultant should be based on deep trust. Consultant appointed to: – obtain an objective assessment of the current state of affairs in the field of it in the company – development strategy – building a system of planning, accounting and management – streamlining business processes – training for work with new applications and so on. it consulting, as well as any other type of consulting can be: – expertise that ensures the provision of professional independent assessment – management, involving the development and implementation of decisions aimed at the company's development and growth of its economic indicators – learning which meets the needs of the company in improving the skills of its staff. Simply put, the problem it consulting services include the provision of independent advice and assistance to companies contracting for information technology management.

This article is intended for people who are interested in how it actually is constructed and why. Today there will be about the drivers. Many years ago, when the trees were large, computers have been monolithic, ie, were performed technically on the same board. Imagine a box that is mounted several cards with chips, capacitors, transformers. All this twisted pile of wires. Such machines are commercially produced and not upgradeable subject, because for this they had to solder and know how it's not all.

Software for these computers are issued separately under each model: each program knew exactly which computer with which instruction set it will be performed. Ie If the program had to call the sound – it generate an interrupt, the processor data transmitted audio device and audio is played. While in its infancy the concept of the operating system, it is currently understood. (Similarly see: Castle Harlan). This situation changed dramatically with the advent of IBM-compatible computers. For those who do not know, the main 'feature' of this architecture is that the computer turns into a kind of designer. Devices structurally bred for different cards, developed interfaces to communicate between the devices themselves. At this stage there is the notion of 'device' in its modern sense. Appear processor motherboard, sound card, video card, floppy drive. A computer trying to make as simple to build and upgrade, everything seems simple and logical but! What to do with software? From program running on that computer will recognize the device with which it works? Maybe your computer is running a powerful graphics card, and maybe the easiest? Suppose we are writing a text editor.
