This document discusses the key components of IT infrastructure, including computer hardware platforms, operating system platforms, enterprise software applications, data management and storage, networking and telecommunications platforms, internet platforms, and consulting and system integration services. It provides details on each of the seven major components that make up an organization's overall IT infrastructure. The infrastructure refers to all the hardware, software, networks and related equipment necessary to develop, operate and support IT services.

IT:
Information technology (IT) is the use of any computers, storage, networking and other physical
devices, infrastructure and processes to create, process, store, secure and exchange all forms of
electronic data.
Infrastructure:
Infrastructure is the fundamental facilities and systems serving a country, city, or other area,
including the services and facilities necessary for its economy to function.
Introduction:
The term infrastructure in an IT context refers to an enterprise entire collection of hardware,
software, networks, data centers, facilities and related equipment used to develop, test, operate,
monitor, manage or support information technology services.
IT infrastructure consists of all components that play a role in
overall IT. It can be used for internal business operations or developing customer IT or business
solutions.
Infrastructure Components:
IT infrastructure
Computer hardware platforms
Operating system platform
Enterprise and other
software applications
Data management
and storage
Networking and
telecommunications
platforms
Internet platforms
Consulting and system
integration services

3. Seven major components of IT infrastructure are as follows:
1. Computer hardware platforms
2. Operating system platforms
3. Enterprise and othersoftware applications
4. Data management and storage
5. Networking and telecommunications platforms
6. Internet platforms
7. Consulting and system integration services
Computer hardware platforms:
computer hardware platform included client and server machines, as well as modern
mainframes produced by IBM. Blade servers are ultrathin servers, intended for a single
dedicated application, and are mounted in space-saving racks.
Operating system platforms:
It include platforms for client computers, dominated by Windows operating systems, and servers, dominated by the
various forms of the UNIX operating system or Linux. Operating systems are software that manage the resources
and activities of the computer and act as an interface for the user.
Enterprise and other software applications:
It include SAP, Oracle, and PeopleSoft, and middleware software that are used to link a firm's existing
application systems.
Data management and storage:
Data management and storage is handled by database management software and storage devices include
traditional storage methods, such as disk arrays and tape libraries, and newer network-based storage
technologies such as storage area networks (SANs). SANs connect multiple storage devices on dedicated
high-speed networks.
Networking and telecommunications platforms:
Networking and telecommunication platform include Windows server operating systems, Novell, Linux, and
UNIX. Nearly all LAN and many wide area networks (WANs) use the TCP/IP standards for networking.
Internet platforms:
Internet platform overlap with, and must relate to, the firm's general networking
infrastructure and hardware and software platforms. Internet-related infrastructure
includes the hardware, software and services to maintain corporate Web sites, intranets,
and extranets, including Web hosting services and Web software application development

4. tools. A Web hosting service maintains a large Web server, or series of servers, and
provides fee-paying subscribers with space to maintain their Web sites.
Consulting and system integration services:
Consulting and system integration services are relied on for integrating a firm's legacy
systems with new technology and infrastructure and providing expertise in implementing
new infrastructure along with relevant changes in business processes, training, and
software integration. Legacy systems are generally older transaction processing systems
created for mainframe computers that continue to be used to avoid the high cost of
replacing or redesigning them.
