Introduction
The report is prepared for www.cosboa.org.au which was founded in the year 1977
and the goal of the organization is promotion and supporting small business development in
Australia. The company engages the members for providing them opportunity of influencing
outcome of the business. An essential input is provided by the members of the company for
ensuring that the representation quality is met. The company helps the small business
organization to promote their interest with changing their policy and reforming the
regulatory. It increases the awareness and help them to understand the role of small business
in Australia. For the development of the report it is assumed that the organization would open
a new branch in a new building at Sydney city centre.
1. IT infrastructure proposal
For the development of the network infrastructure an analysis is made on the floor
plan of the building and number of rooms per floor. The data points that are needed to be
available per room is analysed for the development of IP addressing plan and creating a
logical design of the network. The geographical scope of the network is discussed with the
use of the diagram and explanation is provided for the network device used as the backbone
for connecting the network with the small business organizational network. In the second part
of the report a discussion is provided on the organisation that provides cloud service and can
be used by the organization for hosting email and web server for the organization. The
techniques that can be used for virtualization of the service and support the implementation of
cloud platform is also given in the report. The support of cloud computing for supporting
dynamic scaling of the organisation application is also discussed in the report.

IT INFRASTRUCTURE
The network solution developed for Cosboa would help the organization to improve
the business operation and marketing. The satisfaction of the customer can be improved with
the improvement of the service and extending the new branch to connect with the other
branches of the organization. The network is needed to be designed such that it can be
accessed from remote location and the users of the network can securely share files and
information between themselves. For the development of the network the network is
segmented with the inclusion of repeaters, switch and other units.
A local area network is created that connects the users in the network and the multiple
LANs connects with the backbone of the network for forming a larger network. The network
is designed and evaluated for minimizing the disruption and eliminating the risk associated
with the development of the network framework. The Sydney network is needed to be
connected with the other branches and it can be accessed via VPN. For connecting the remote
site point to point, frame relay and ATM and other types of long distance connection can be
used for connecting the branch.
