INFASTRUCTURE
Components of
It
infrastructureTypically IT infrastructure is composed of the
following components:
 Hardware: Computers, data centers,
hubs, switches, routers, servers and
other parts.
 Software: Customer relationship
management or CRM, Enterprise
resource planning or ERP, productivity
applications and other software.
 Network: Internet connection, internet
security, firewall and network
enablement.
 Humans: Developers, Network
administrators, designers and end users
using an IT device.
Security
issues in cloud
computing
The top 5 cloud computing security issues include:
 There is a lack of visibility into knowing what
data is inside the cloud applications.
 Data theft from a cloud server by a hacker or
cyber criminal.
 No fixed guideline or access level for accessing
sensitive data.
 The data being transferred in and out of the
cloud server cannot be monitored.
 The level of threats against cloud computing
are getting more advanced over time.
Virtualizatio
n in IT
infrastructu
re
The main uses of virtualization and
cloud computing are:
 The security is improved due
to encryption of the stored
data and multiple security
firewalls in cloud.
 Cloud computing and
virtualization is quite
economical and saves a lot of
money for the company.
 These technologies makes the
company more agile and
efficient.
Role and
responsibility of an IT
infrastructure
manager
The main role and responsibilities of an IT infrastructure manager are:
 Staff management: The manager is responsible for overseeing
operations related to networking, physical cabling and servers.
The manager is responsible for smooth functioning of these
systems.
 The manager is responsible for building strong relationships with
third party vendors needed by the company.
 The manager is responsible for establishing proper procedures
and standards to reduce complexity in working.
 The manager is responsible looking out for and implementing
latest technologies that would benefit the company in the future.
Dynamic scaling
of applications
Scalability is an important factor to consider for the success of the
company. The maintenance of adequate requirements is costly for
meeting the peak performance. Cloud computing helps here by
providing a very powerful computing environment that allows user to
use resources on demand. This technology can be used to create
web applications that scale dynamically based on the virtualized
cloud computing environment. This helps in auto allocating resources
dynamically as and when required and save resources when the load
is low. This benefits the company in handling sudden load surges well
and maintains more resource usage thus leading to low management
and infrastructure costs.
