Part 1: PowerPoint Presentation on Cloud Architecture
Slide 1: Title Slide
Slide 2: Major Concepts of Cloud Computing
Slide Note: Cloud computing is the secured transfer of data on the Internet.
The main concepts of this cloud computing are as follows:
i) Infrastructure as a Service or IaaS

ii) Platform as a Service or PaaS
iii) Software as a Service or SaaS (Hashizume et al., 2013).
Slide 3: Selection of Cloud Infrastructure
Slide Note: The IaaS or the Infrastructure as a Service would be the best solution for the
organization of Regional Gardens Ltd.
There are various important advantages of this IaaS. They are as follows:
i) Scalability and Elasticity: It is scalable and provides elasticity.
ii) Flexibility: It is flexible enough to manage all types of problems (Dinh et al., 2013).
iii) Cost Effective: IaaS is extremely cost effective in terms of infrastructure costs.
iv) DR Plan: IaaS comprises of DR or disaster recovery plan within it.

Slide 4: Cloud Deployment
Slide Note: The organization of Regional Gardens Ltd. is using an obsolete infrastructure in
their business. Windows Server 2008 and Linux 2008 are utilized as their infrastructure
(Kavis, 2014).
Thus, IaaS would be the best solution in this purpose. They should migrate to Infrastructure
as a Service for getting all the advantages of this particular cloud architecture model. this
would reduce all of their issues related to infrastructure.

Part 2: Office Automation for Regional Gardens Ltd.
Two types of approaches are possible for office automation of Regional Gardens Ltd.
They are structured approach and ad hoc approach.
Structured Approach with its Benefits as well as Disadvantages
This is the first important approach for the office automation system of Regional
Gardens Ltd. There are various advantages as well as disadvantages of this particular
approach. The main advantages of the structured approach include following of significant
processes and user friendliness. Since it follows a series of processes for completing the
office automation system there are several important phenomenon of this approach. It is
well accepted by all the enterprises, who want a structured approach for their office
automation. The second benefit is the user friendliness. Every organization can easily utilize
this approach as it is extremely simple.
Several disadvantages are also present in the structured approach. The most
significant disadvantage of the structured approach is providing erroneous data. The output
is often inaccurate and thus many organizations do not want to take up this approach. The
second disadvantage of the structured approach is that it is very slow in comparison to
other approaches.
Ad Hoc Approach with its Benefits as well as Disadvantages
This is the second approach for the office automation system of Regional Gardens
Ltd. The most significant benefits of this ad hoc approach mainly involve the easy and
simplified application and the excess speed. Since, this is an extremely easy and simple
application; it could be easily utilized by all small and medium sized organizations. The

second advantage of this ad hoc approach is that it is extremely fast than all the other
approaches and thus many organizations utilize this particular approach for their office
automation in business. The third significant advantage of the ad hoc approach is that it is
cost effective and do not involve much costs for automating the system.
There is only one major disadvantage present within the approach of ad hoc. The
approach of ad hoc does not follow any specific procedure. Since, this does not follow any
specific procedure; the ad hoc approach is often considered as not suitable for the
organizations who deal with bulk amount of data.
Recommendation regarding the Approach
The most suitable approach for the organization of Regional Gardens Ltd. would be
Ad hoc approach. This particular approach is cost effective, simplified application, easy
application and without documentation. For all these advantages, this approach would be
very effective and efficient for office automation system.

Part 3: Migration to IaaS or PaaS
The organization of Regional Gardens Ltd. should migrate their obsolete web
infrastructure to either IaaS or PaaS.
Differences between IaaS and PaaS
The differences amongst IaaS and PaaS are as follows:
Important Factors IaaS PaaS
Definition Infrastructure as a Service is the
virtualized infrastructure that is
provided to the users for
various online services.
Platform as a Service is the
online platform that is provided
to the users for helping with
various platforms related
functions.
Benefits i) Diminishing costs in
infrastructure.
ii) Scalability.
iii) Flexibility.
Iv) Agility.
i) Cheaper than IaaS.
ii) High developing speed.
iii) High deploying speed.
Iv) Easy application
management.
Issues i) Very costly.
ii) Client Backup required.
i) No data security.
ii) No control on platforms.
Examples Amazon Web Services. Google App Engine.
After taking into consideration, the major issue in the Infrastructure as a service is
the expenses. It is very expensive and thus could not be afforded by the small and medium
organizations. In case of Platform as a Service, there is almost no security in data and thus
8

the many organizations avoid this cloud architecture. If there is no backup taken for the
data, it is better to avoid Platform as a service.
After considering all the merits and demerits of Infrastructure as a service and
Platform as a service, it would be the best for the Regional Gardens Ltd. to select
Infrastructure as a service for their organization.

Part 4: Recommendation about Cloud Models for Regional Gardens Ltd.
Three options are present for cloud model architecture for the organization of
Regional Gardens Ltd: IaaS, PaaS and SaaS.
Differences between IaaS, PaaS and SaaS
The major differences between Infrastructure as a service, Platform as a Service and
Software as a service are as follows:
Important
Factors
Infrastructure as a
Service (IaaS)
Platform as a Service
(PaaS)
Software as a Service
(SaaS)
Definition Infrastructure as a Service
is the virtualized
infrastructure that is
provided to the users for
various online services.
Platform as a Service is
the online platform that is
provided to the users for
helping with various

functions.
Software as a Service is
software delivery model
that is utilized for
providing on demand
services.
Benefits i) Diminishing costs in
infrastructure.
ii) Scalability.
iii) Flexibility.
Iv) Agility.
i) Cheaper than IaaS.
ii) High developing speed.
iii) High deploying speed.
Iv) Easy application
management.
i) Cheapest.
ii) Without Complexity.
iii) Flexibility and
Scalability.
iv) Easy Accessibility.

Recommendation about Cloud Model in Regional Gardens Ltd.
Regional Gardens Ltd. is unsure about the migration to cloud. The selection of their
cloud should be done by taking into consideration of various advantages of the three.
Amongst the three cloud architecture models, the recommended model for this particular
organization is the Infrastructure as a Service. There are various benefits of this architecture
and since all the benefits are present in the cloud service model, they should select this.
The most significant advantages of the Infrastructure as a Service mainly include its
security, safety, reduced infrastructure costs, flexibility, scalability and speed. It is very safe
as well as secured and thus data migration is easier. It is extremely flexible and scalable.
Moreover, it helps to reduce the infrastructure expenses and can be afforded by Regional
Gardens Ltd. The next advantage of this particular cloud model of Infrastructure as a Service
is the speed. It is extremely fast and thus all organizations adopt this model.
Issues with Recommended Model with their Solutions
However, there are few issues or problems present within the cloud model of
Infrastructure as a Service. The most important issue is the vendor dependency. It is
completely dependent on the vendors and thus often security issues arise with this model.
The only solution to this particular model is that only trustworthy vendors should be
involved in the process. The second problem is that it very costly and often small enterprises
cannot afford them. The only solution to this problem is that a comparatively cheaper cloud
vendor should be selected.
