IT Infrastructure: Components, Security Issues, and Role of IT Infrastructure Manager

 Computer hardware platforms: It
includes server machines and
client machines
 Operating System platform: OS are
the software that manages the
activities and resources of
computers.
 Software applications: It is used to
link the existing application
systems of a firm.
 Data management: Data
management software handles the
data of a firm (Alsabawy, Cater-
Steel and Soar 2013).
 Server: It is the centre of
connection for all the components.
 Network switch: It creates a
network on which the entire system
operates.
 Data centre: It is a physical storage
facility that houses entire system
The above discussion concludes
that IT infrastructure is a set up of
systems that are required for
operating an IT environment. The
cloud computing and virtualisation
provide various solutions to the IT
infrastructure.

IT infrastructure is a composition of
software, hardware, services and
network resources that are required
for existence, management and
operation of an enterprise Information
Technology environment. It allows the
organisations to provide solutions and
services to their employees and
customers.
Virtualisation is a system in IT
infrastructure that allows the firm to
run several OS and applications on
same server and at the same time.
There are several security issues
for the data of a firm due to the
use of cloud services as an IT
infrastructure solution.
 Data breach may take place.
 The service provider will have
the access to the confidential
data of the organisation.
 A malware injection can
compromise the entire data of
the firm.

Dynamic scaling
Dynamic scaling allows the IT
firms to use the resources on
demand. It provides the ability to
the organisations to handle
growing or diminishing resources
in order to reach the business
demands in an efficient way.
