All the services that are included in the Information Technology are delivered by the
process of cloud computing. The services are mainly done on the tools that are web-based and
applications that are web based. The cloud system helps to keep the files safe in a remote
storage instead of keeping them in the system hardware.

The service of cloud computing provides many services to all the companies that uses
the system.
1. Cost: The cost of the overall software and hardware are decreased by the help of cloud
computing.
2. Speed: Generally the speed of all the computer services that are demanded by the
companies and businesses are fulfilled by cloud computing in a very fast way.
3. Global Scale: The cloud computing helps to increase the elasticity of the service that are
provided by the providers of cloud computing.

increasing the speed of the processes.
5. Performance: The work that is done by cloud service providers are done at a high speed.
6. Reliability: The cloud computing helps to securely store all the data that are stored in
the cloud.

PaaS is a model of cloud mainly designed for the software developers, which narrows
the process of development. PaaS is a model used by software developers, which generally
narrows the development of the shifting process. PaaS is basically used to develop the mobile
applications and the web application that are configured previously.

SaaS is a model that gives delivery of applications on-demand and also delivers
applications that are managed and hosted by service providers. There are many advantages of
cloud computing. The model of SaaS is the most effective service of cloud as only the software
is leased and the resource is not leased. Less amount of planning is required by SaaS and the
implementation is very easy. There is rapid deployment of the network as the service is
provisioned when on demand. The applications are not needed to be managed by the users a
because all things are done by the service provider. The software of SaaS is very stable.

2. Office Automation System of Regional Gardens Ltd
1. Two Different Approach of Office Automation in Regional Gardens
Two different approaches are usually there that Regional Gardens can implement. The
approaches are Integrated Office Automation System and the second one is the Cloud
Computing Approach.
Traditional Automation System:
Name-
Student Number-

14OFFICE AUTOMATION FOR REGIONAL GARDENS
The first office automation system that Regional Gardens can implement is the
traditional office automation system (Oliveira, Thomas & Espadanal, 2014). Traditional office
automation system works on the existing structure of the office. In this approach, the structure
of the office is kept same with all the processes of the offices constant of achieving the same
unchanged objective.
Integrated Automation System:
The second automation system that Regional Gardens can use is the concept of
integrated automation system. In this system, the structure of the office is totally changed or
redesigned along with all the automation process involved in the office (Rodriguez & Buyya,
2017). All the flow of information that are involved in the organization are needed to make the
office an integrated office automation system.
2. Advantages and Disadvantages of each Approach
Approaches Advantages Disadvantages
Traditional Automation
System
The main advantage of the
traditional system is that the
retention is allowed on the
present structure of the office
(Rao & Selvamani, 2015). This
retention process is helpful in
such organizations in which
The disadvantage of this
approach is all the automated
tasks that are involved in the
organization are un-

consequence may collect the

system. With redundancy,
possibility of alterating the
data increases.
Integrated Automation
System
The advantage of integrated
automation system is that the
system helps to optimize the
processing system of
information by eliminating the
redundancies and all the
unnecessary flow of the
paths. This helps to define the
structure of the organization.
Cost of reconstructing process
is comparatively higher than
the traditional method
(Sadiku, Musa & Momoh,
2014).
Table 1: Advantages and Disadvantages of Traditional model and Integrated Model
3. Recommendation for using an Approach of Office Automation
However, neither of the office automation system is appropriate for running an office
alone. To maintain the office in Regional Gardens, both the system can be combined together
to make the office automation system more stronger (Bernstein, 2014). The best example of
combination of both the systems is the Cloud Computing approach. The cloud computing is an
integrated system, which use remote network servers on Internet for the purpose of storing,
managing, and processing the data instead of personal computer.

3. Web Infrastructure of Regional Gardens
1. Difference between IaaS and PaaS Infrastructure
Features IaaS PaaS
Definition IaaS is one of the form of
cloud computing, which
generally provides computer
resource that are virtualized
on internet (Rittinghouse &
Ransome, 2016).
PaaS is a model of cloud
mainly designed for the
software developers, which
narrows the process of
development (Manvi &
Shyam, 2014).
Advantages  The customers in the
organization have full
control on their virtual
machine and all the
components inside
them.
 Simplifies the
integration with the
enterprise
infrastructure.
 In this approach,
there are improved
supports for
integration.
 The virtual machine is
not managed in PaaS.
Disadvantages  Customers are mainly
responsible for the
backups that are to be

2. Recommendation among three models for SharePoint Service
The best Cloud Computing model that Regional Gardens Ltd can use in their office to use
SharePoint services is the Infrastructure as a Service model. This service provides a wide range
of services to accompany the infrastructure of Regional Gardens Ltd (Ali, Khan & Vasilakos,
2015). This model will help to make the processes such as billing, monitoring, load balancing,
clustering, security as well as storage resiliency including replication, recovery, and backup.
Automation is provided by the IaaS implementation.

Figure 2: IaaS Structure
3. Issues with the recommended model
The recommended model for Regional gardens Ltd is the IaaS Cloud Computing model.
1) The IaaS is the most expensive model among all three cloud computing models. The service
provider of IaaS charges a lot for only a little amount of space (Botta et al., 2016).
2) The backups are to be done by the customers themselves, which can lead to some mistake.
3) The management of VM is done by the user that is an extra burden for the users.
4) There is no control on the server in IaaS.

Dealing with the issues
There are many ways to deal with the issues that arise in the IaaS model. The Regional
Gardens Ltd. should develop the strategy of information security that can include the following:
 There should be regular scheduling update of software.
 Patching the procedures included in system.
 Audit and monitors the requirements of the system.
 Vulnerability analysis and regular testing should be included.
