2CLOUD COMPUTING: CONCEPTS AND MODEL
There are various gardening enterprise related to the company of Regional Gardens Ltd.
It sells the plants and garden supplies to public. The Regional Gardens Ltd data center is located
in Bathurst with the infrastructure of the server. The workflow tool of cloud provides flexibility
to their design. The existing process has been changed into the cloud-based infrastructure. The
employees were able to get access control with limited entry into the office premises. The
integral part of the automation system understands the requirement. Employees and public can
access cloud-based workflow from anywhere. This study will provide the information about the
approaches made to Office automation with its benefits and issues. It will also recommend with
the best feature that can be used as a Service provider by understanding the basic difference
between the PaaS and IaaS model. The benefits that the model provide and the issue arises with
the use of such model. The study will also give the reason for selecting the appropriate model
and provide with solution to the issue if arise any during the implementation of such model.
1. a. Office automation approaches
The Regional Garden provide access to office automation namely spreadsheet, word
processing, email, online file storage at home, in the office, or deployed in the field on the
customer’s site (Alam, Pandey & Rautaray, 2015). Two of the different approaches of Office
automation that can be provided to the staff are:
Report and analytic
To know the results yield by the office automation, the ultimate decision-maker is the
data that is important for the company to compare the outcome of the quality, process history and
the cost made for selling the plant and supplies of garden to the public. It would be time-
consuming if the company adopts any other software to measure the data of workflow

unnecessarily. As it involves multiple teams if the process has other software dependencies
(Demirkan et al., 2015). Thus, a single piece of software has embedded with the feature of
Report and analytic would be a better approach for them.
Mobile Compatibility
It is not possible for the manager to always be around the employees checking through
their work. There is a simple solution to this in today’s evolving technology. The employees
have to just pick a workflow of the automation system that is cloud-based (Gai et al., 2016). This
will enable the employee to access the office automation from anywhere. Thus, this feature
comes with the feature of great mobile compatibility that has a Cloud-based workflow.
1. b. Benefits and Issue
Office automation provides efficiency to the workflow (Deelman et al., 2015). The
benefits of automation in the office workflows are:
 Cutting down the manual error and intervention of the human
 Completing a mundane tasks and reduces the effort that was made manually
 Some of the invaluable resources and time has save
 Identifying and gaining process visibility
 Based on the change and process demand, the business decisions have made
 The metrics performance process are known
1. c. Summary and Recommendation
Cloud computing is a service assortment that meet the IT needs of Regional Garden Ltd.
In conclusion, it is just a concern about the time consumption, cost and security that the

4CLOUD COMPUTING: CONCEPTS AND MODEL
employees were facing trouble. Cloud has brought substantial technical and economic benefits fo
the company. One such IT need that has been recommended is the infrastructure-as-a-service
(IaaS), as it will deliver a virtualized resource of computing for the company through internet
(Almorsy, Grundy & Müller, 2016). The company can self-provision the service infrastructure
and pay per-use on monthly, weekly or hourly basis. This model can be an appropriate one and it
can approach to the need of the user of cloud computing service as the Service Provider and
Service Orientation of the business model offer complete business services.
2. a. Difference between IaaS & PaaS model
Regional Garden has to decide whether to use IaaS model or PaaS model that provides
cloud services as their infrastructure deployment to their employee. The difference has discussed
below, as they initially wanted to move their Web infrastructure to public Cloud. These
differences will let them identify which platform would be better for them.
PaaS refers to “Platform-as-a- Service”. PaaS provides a platform where the software has
to developed and deployed. A PaaS provider mostly deals with servers that take care of the
environment of the operating system, server software, server hardware and the infrastructure of
the network (Puthal et al., 2015). The providers of PaaS include Red Hat’s, Google App Engine,
Heroku and OpenShift.
IaaS stands for “Infrastructure-as-a-Service”. An IaaS provider provides scalable
compute resources and the highly automated cloud storage through API and dashboard (Botta e
al., 2016). It is the most flexible model for the storage, servers, networking and processing power
automated deployment. The clients that use IaaS infrastructure have better control than the PaaS

5CLOUD COMPUTING: CONCEPTS AND MODEL
and SaaS services. IaaS is mainly use for web-scale applications and actual deployment and
development of SaaS and PaaS.
2. b. Benefits & issues
The benefit that has to achieve by the use of PaaS are (Paraiso, Merle & Seinturier, 2016):
 Developing and deploying a simple application with cost effective
 Availability will be high
 Is scalable
 Without any proper maintenance of the software, developers will have the ability to
create an app with customization
 Coding get reduces
 Policy of the business get automate
 Easily migrate to hybrid model
The benefit that has to achieve by the use of IaaS are (Iosup, Prodan & Epema, 2014):
 It is the most flexible model of cloud computing
 Highly scalable
 The deployment of network servers, processing powers and storage get automated easily.
 Purchasing of hardware through better consumption
 Clients have complete control over their infrastructure
 As per the requirement resources has to be purchased

3. a. Model Selection
It is recommended to the Regional Garden to migrate their Web infrastructure and choose
IaaS service provider. The reason to choose IaaS is that it has the capability to purchase
resources for the business that are on-demand and when needed rather than buying a hardware
outright. Through Virtualization Technology IaaS would be able to deliver infrastructure of
Cloud Computing in which storage, network, servers and operating systems are included (Manvi
& Shyam, 2014). They would have complete control over the entire infrastructure, as it would
provide virtual data center that can access the storage and server directly.
3. b. Discuss Model appropriateness
The IaaS model is appropriate to use for the characteristic that it provide. Today it is the
modern data center platform. The purpose of this model being presented is to provide with best
solutions for the formation of cloud model for the company that are appropriate as per the need
of the employee. It has available resources for the services that are highly scalable
(Abdelmaboud et al., 2015). The virtualization technology of IaaS manages the resources such as
network technology, server, media storage and lot more. Cloud provider is dynamic for IaaS, it
can either enlarge or reduce the infrastructure depending on the need of the employee and the
public. As per the consumption, the cost varies. It provides a complete control of their
infrastructure as it is flexible and dynamic.
3. c. Model issues and solutions
The major issue of IaaS is that employees can have direct access to hardware and the
networks (Ali, Khan & Vasilakos, 2015). They can even have access to systems provision,
hypervisors and infrastructure that need authentication. Due to the amount of data being large, it

7CLOUD COMPUTING: CONCEPTS AND MODEL
become easier for attackers to target the platform that have IaaS provider. This risk can be reduce
by minimizing the drivers of virtualization and the supported features of hypervisor and tools of
intrusion detection. It already have an advance security features. It require regular software
updates, vulnerabilities analysis, regular testing, monitoring and auditing.
