INTRODUCTION
Medical consultancies need to upgrade their operations from a smaller site to a
larger one. In London, there is a small site where they are secured to manage the
interactions of the business in the south part of England. The head office is located in
Manchester where the operations are supported in the north side of England and
managing international clientele.
The firm consists of the following infrastructures:
 The business process is executed in digital format so the performance and the
availability will be more.
 Security is essential where the medical history about the clients are stored in
the consultancies.
 The datacenter is available at the main branch in Manchester
 Totally there are 30 consulting executives in London but there is no updation
related to technology infrastructure so it should be implemented.
It is necessary to represent the technology proposal to the chief information officer
as an infrastructural architect. This proposal contains information about the
infrastructure options that are available in the computing infrastructure for
supporting the digital services that are required in the new location. To justify the
proposed system the hardware and software related to the infrastructures that are
necessary to provide the digital services. In addition to that, the network strategy
and protocols involved in providing the digital services are described. Infrastructure

is depicted in the form of a network diagram. Assumptions are made to fulfil the
requirements of the proposed system.
INFRASTRUCTURE MODELS
Infrastructure is the framework that provides the facilities to the organization. In
computing IT infrastructure consists of physical and virtual resources that provide
storage space, processing mechanism, flow and data analysis. Infrastructure can be
centralized with a data center or decentralized so that the data can be controlled
and managed by the third-party service provider (Lupou, Dorobanţu and Fiore 2010).
On-premises
On-premises is a traditional Enterprise Resource Planning (ERP) system where it is a
software that can be customized. It is a centralized system where all the system are
connected with the data center. There are three types of ERP system that the
organization can afford. They can purchase the software license and after getting it
they can be deployed in the data center. It is considered to be the safest and reliable
system solution. With this solution, the organization can rent the complete package
and the delivery mechanism (Navaneethakrishnan 2013).
Benefits
 It can be cheap in terms of long duration
 There is no access provided to the third party services provider either full
control is within the organization.
 Physical control towards the hardware is controlled tightly

 IT experts are available at anytime
Drawbacks
 Hardware and software costs are high
 If necessary experts are not available then the organization security will be
under risk.
 In case of any demand, it should be preplanned since the required hardware
should be researched, ordered and deployed.
Necessary Hardware, software and services
 Desktop PCs
 Printers
 Data centers
 Network devices
 ERP software
On-premises vs cloud
In today’s environment, the IT infrastructure consists of various factors that the
organization has to choose it. Still, there are more companies who cannot upgrade
their organization using the cloud instead they use on-premise software and
applications for performing business operations. In on-premise computing, the data
is hosted by using software that is installed in the company’s server but in cloud

computing, the data is hosted by the third party services (Miah, Hasan and
Gammack 2017).
In on-premises, the software is installed on every server in the company where it
offers the services for a long duration and it may be continued till its needs. Also, the
applications will be reliable and secure. But in organizations, they need cloud
applications to meet their organization's goals.
Cloud
Cloud allows the users to access the resources on a measured basis using an
internet connection. Basic resources such as storage, networking, computing are
required for processing the business (Nazir 2012).
Definition of cloud computing
Cloud computing is the delivery of computing resources on measured services via
the internet. it can be scaled up and paid based on the usage (Gibson, Rondeau,
Eveleigh and Tan,2012) (Griebel & Prokosch, 2015). .
Characteristics of Cloud Computing
 On-demand services
 Broad network access
 Elasticity
 Resource pool
 On-demand services

Benefits of Cloud Computing
 It is cost-efficiency
 It provides enormous resource availability
 Backup and recovery is very simple
 Its environment is friendly and requires minimum resources to save energy
 Its scalability
 Increased storage capacity
Drawbacks of Cloud Computing
 Security is a great barrier
 Its dependency on the third-party service provider
CLOUD SERVICE MODELS
Cloud services models are as follows (Gibson, Rondeau, Eveleigh and Tan 2012),
(Zhang, Cheng and Boutaba, 2010):
 Software as a Service (SaaS)
 Platform as a Service (PaaS)
 Infrastructure as a Service (IaaS)
Software as a Service (SaaS)
The tradition model that is used in cloud computing for distributing the software,
purchasing and installing in the PCs. The applications are hosted by the third-party
service provider and they will make the customer access it via the network. the
usage of SaaS is increased since many web services and architectures are widely

used. It can also be used by on-demand services with the license. Examples of SaaS
are Gmail, instant messages from Yahoo, Google etc.
Platform as a service (PaaS)
After software, in cloud computing platforms are included for running the web
applications. This is a platform as a service. It is a growth of the software as a
service model. It provides all the requirements for services of the web applications
with no requirement for downloading and installing the software. Examples of PaaS
are Microsoft Azure, salesforce.com etc.
Infrastructure as a Service (IaaS)
It provides resources such as storage, networks, processing, servers that can make
the customer deploy and run the software where it also consists of operating
systems. Examples of IaaS is Amazon EC2.
CLOUD DEPLOYMENT MODELS
The following models are the cloud deployment models (Bojanova and Samba 2011)
(Rao, Leelarani and Kumar 2013)
 Public cloud
 Private cloud
 Hybrid cloud
 Community cloud
Public cloud
