ENTERPRISE SERVER MANAGEMENT
Introduction
In modern times, with the increase of services demand and information requirement,
majority of the conventional services are not being able to provide efficient services. The
multi-million pound business has shifted from their conventional sales in person to the e-
commerce system. The main issue that is faced in the company is the failure of one IT device
that led to the failure of entire system of the company. This report intends to analyse the
services that needs modernisation and improved hardware for ensuring that IT system failure
is not experienced by the company. The services that are required to be improved has been
analysed through the in-house setup and cloud options for determining the most appropriate
solution for the company.
Discussion
In-house options
The required infrastructure for the company could be created in-house or created in
the cloud. The in-house setup of the services could be done using the virtual windows server
and the identification of the services that are required to be installed is done. The primary
requirement of the configuring such a network is the identification of number of departments
as well as the services requirements. Then the server could be connected with organisational
network for fulfilling the requirements of all users. Identification of the present problems has
to be done and then configuration of the server with the services and roles is done for
mitigating the problem as well as increase the efficiency of present business functions. The
file server has is required to be configured and there is a requirement of creation of group of
users for managing the permission as well as allow the access and the restriction of users for
files. Space is required to be provided to the users for storing the files and therefore the
utilisation of the configuration of the file server is done. IIS service could be used for

configuring with the server to allow the hosting of the service of internal website for this
company and allow the communication among all users of each department as well as the
branches. Print server is required to be configured with the server as well as provide the
facility of printing the files as well as the documents for the users using remote printer.
Sharing of the network printer is done with each of the users to enable the access to the
printer. Enabling of the DHCP service could be done to eliminate problems of the manual
configuration of IP as well as automatically assign the IP address to device that has been
connected in network.
Print servers for the users: Enabling of the print service is done for the users for
allowing the sharing of the network printer in the organisations with each department as well
as allowing the access to printer among each department. It could be considered that the
utilisation of the printing service could help in eliminating the requirement of printers for
each department by introducing a sole printer for the management of printer jobs.
Cloud options
When the consideration of cloud is done for designing any network that efficiently
supports all required applications, services as well as data, the unique challenge that is faced
by the organisations is the selection of the most appropriate cloud architecture (Choi et al.
2018). As the business frequently do not own their respective cloud components, there are
limited options available. The technologies of cloud networking have advanced in the modern
times where there are several options that offers varying levels of the network design based
on the requirements (Illsley 2016). The concept of the cloud networks mainly emphasises on
ability of the cloud customer of designing, configuring as well as managing their respective
network in any private or even the public cloud (Baker et al. 2019). With the introduction of
any private cloud, the network architect of the company gains significant flexibility when the
consideration of complete design is done due to the fact that the cloud provider completely

ENTERPRISE SERVER MANAGEMENT
manages the respective software as well as the hardware of the company on which cloud has
been developed (Wang et al. 2018). For the public clouds, the customers could control as well
as manage the networking only in the deployments that are IaaS. With the PaaS and the SaaS
services, the customers are not provided with the overall control over the network functions
as the network is completely handled and monitored by service provider (Madhuri and
Sowjanya 2016). For this particular reason, for gaining the ability configuring aspects of the
network in the public cloud, the sole option is the IaaS services (Villamizar et al. 2016). For
the considered company, the most appropriate cloud architecture is the hybrid cloud. The
hybrid architecture mainly denotes that the applications, services as well as the data resides in
the corporate-owned as well as managed data centres, while the others have shifted to any
infrastructure of IaaS provider. For the customers with the hybrid model, the most
appropriate scenario is the mimicking network IP space, the procedures as well as the policies
that are already been implemented in the data centres (McGrath et al. 2016). The replication
of the similar processes as well as the settings in the cloud environment allows the creation of
significantly more uniform experience of the administration and end-user (Nair 2018).
The evaluation of the available cloud network architecture could be done for
determining the most appropriate network architecture for the company. The business could
use the following cloud network architecture that is Amazon virtual private cloud service.
The company could use the Amazon virtual private cloud service and then it could gain the
control over basics like the assigning of the private IP addresses of choice, segregation of the
virtual network into several subnets, as well as creation along with applying various security
policies to each of the subnet (Snyder and Jones 2019). The company could have their control
over route table, the supplemental network services as well as the internal gateways.

Implementation time and difficulty
The recommended architecture of Web could be considered as the client-server model
where as the result, the main concern is the communication among the client as well as the
server. The system of client server is analysed to have minimised application development
time as the development is done by segregating the functions of sharing the information
among client as well as the server whereas the development of the service in the cloud could
take significantly high time. The cloud computing architecture of Amazon virtual private
cloud service is the conceptual model that includes all sub-components as well as the
components that are needed for the cloud computing in any cloud space (Kurniawan 2018).
Cloud offers the on-demand access to the networked pool of the shared resources such as the
applications, servers, networks as well as the storage in spite of the location of the cloud
(Ryan and Lucifredi 2018). For implementing the cloud architecture, it is required to setup
each module of the architecture that takes significantly huge time (Bhatt, Patwa and Sandhu
2017).
Initial and ongoing costs
The main issues with the client server model is the unanticipated additional costs that
could be faced by the organisation. Even though the initial setup of the client server model is
significantly low than the cloud option, the additional costs could be considered as
significantly high. AWS provides significantly low-cost, on-demand IT solutions that could
help in developing as well as launching the applications easily at the minimum costs. Minus
the requirement of minimum upfront investments as well as pay-as-you-go models, the
company would be required to pay for the instances that are used by then and when the
company uses this instance for developing the minimum viable product, iterate as well as
experiment, at the lowest cost possible (Sarkar and Shah 2018). The company could monitor
the usage patterns of IT so that the appropriate cloud instances could be used. It is required by

6
ENTERPRISE SERVER MANAGEMENT
the company to monitor the use of AWS cloud resources with the help of Amazon
cloudWatch that could help in gaining significantly actionable insights as well as the metrics
for helping with the management of usage in highly cost-effective manner. The company
could use auto scaling for scaling the capacity of the cloud during any demand spikes, or
down when there is lulling of demand for minimising costs. The infrastructure could be easily
automated and the peaks could be easily handled in the workloads or traffic for further
reducing the costs. The company could take significant advantage of the multiple models of
pricing for the computation services that offers the resizable capacity of computing in cloud.
Based on utilisation of the cloud resources, either heavy, medium or even light, the company
could invest in the ensured reserved capacity as well as pay the low upfront fee for gaining
significantly minimised hourly rate. The pricing model of AWS cloud service significantly
complements the pricing models of On-demand as well as the reserved instance allowing the
potential cost-effective solution for gaining the compute capacity, based on the requirement.
The spot instances could help in significantly lowering the costs of computing for the time-
flexible, interruption-accepting tasks and could be frequently less costly than the on-demand
instances.
Ongoing maintenance
The company could face significant issues in the aspect of the maintenance of the in-
house solution but with the introduction of the cloud, the cloud service provider has the sole
responsibility of maintenance of the model and the company is not required to worry
regarding the maintenance. In the proposed AWS cloud, the cloud service provider frequently
updates the fleet of AWS with several upgrades as well as fleets that are applied in the
instances transparently. Recent release of the scheduled events offers significantly higher
visibility into timing of the reboots (Poornalinga and Rajkumar 2016). Additionally along
with the integrated visibility, the scheduled events could be used by the company for

7
ENTERPRISE SERVER MANAGEMENT
managing the reboots on preferred schedule. The upcoming scheduled events of maintenance
could be easily viewed by the company for the instances in the management console of AWS
or by utilising the command line or the API tools (Mossucca et al. 2015). The reboots like
these are required to be significantly infrequent, but it might be significantly necessary from
significantly time to time for applying the upgrades that could help in strengthening the
security, operational performance as well as the reliability (Villamizar et al. 2017). The cloud
service provider provides two kinds of reboots for the scheduled maintenance, namely the
system reboots as well as instance reboots. The instance reboots could be described as the
reboots that are executed on the virtual instances, and these are equal to the operating system
reboot. The system reboots could be described as the reboots that needs reboots of any
underlying physical server hosting any instance. If any action is not taken, then the impact on
the instance is similar in both the cases, during the scheduled maintenance window, the
instance would experience the reboot that takes significantly less minutes to complete.
Conclusion
From the above discussion, it could be concluded that the company could introduce
the cloud computing technology for gaining several benefits that might not be available in the
in-house option. The in-house setup of the services could be done using the virtual windows
server and the identification of the services that are required to be installed is done. The
primary requirement of the configuring such a network is the identification of number of
departments as well as the services requirements. The company could use the Amazon virtual
private cloud service and then it could gain the control over basics like the assigning of the
private IP addresses of choice, segregation of the virtual network into several subnets. For
implementing the cloud architecture, it is required to setup each module of the architecture
that takes significantly huge time.
