huge garden that opens for show and open investigation couple of time in a year. They have a
few garden undertaking under their watch. This undertaking incorporates the Regional Gardens
Nursery which offers plants and garden supplies to people in general, and Regional Garden
Planners which gives plant guidance, outline and consultancy administrations. The greater part of
their choices and administration orders originate from Bathurst that work as the principle office
where all information are put away in a little database.
Section A: Automation Approach
Nowadays Automation in office not only concerns about the process of mechanizing the
task it also been used as a technology for automate almost every procedures such as storing and
managing staffs resources and lessen the effort of manual managing activities.
Record and Playback
Organizations are constantly called upon for exhortation on planning and conveying
testing computerization apparatuses and structures. Picking the correct mechanization approach
is imperative for guaranteeing appropriate testing, limiting improvement cost and conveying the
most minimal conceivable continuous upkeep costs. Record and Playback is one of the basic
automation approach that provides long term utility with limited flexibility. It functionalities
enables the permits to record user activity and replay them back any number of times and
comparing actual results to those expected. These techniques engage with only hard-coded
information and the functions are highly rely on the automation tool used. Record & Playback
can also be utilized by non-coders while kept customization at a minimum level and sing

graphical verification points. Record & Playback is highly beneficial for basic automation
developments of short period like automated exploratory testing that feature re-record from
scratch or data entry have short test flows and automated data entry.
Benefits: Record & playback is an efficient way for automation approach. This approach has a
number of advantages including ease of deployment, simple design and low development price.
Issues: The basic functions of Record & Playback approaches with a functional price. This
technique has robustness like can break on build and flexibility, restricted performance such as
minimal test flow coverage. Ongoing preservation costs can be high especially when manual
intervention is required.
Data-Driven Frameworks
Data-Driven techniques contain the construction of test scripts to work together with their
associate data sets within a framework. The test environment controls and settings are not hard-
coded. An ideal Data-Driven framework can be utilized when the workflow is monotonous but
the data input is large that means several arrangements of data are essential to effectively test the
application. For implementing this approach an expert team is essential.
Benefits: There are certain benefits using this approach including re-usability of test scripts,
reproducible test results, solid test flow coverage and very good usability.
Disadvantage: There are certain aspects to focus when using this approach. Automation
performance highly depends on automation skills of the user undertaking the implementation.
Regular maintenance also needed to maintain to gain proper efficiency that also increasing costs
and manual intervention upon failure.

IAAS
Infrastructure as a service is recommended for highly automated and scalable resources.
It also has the ability of metered, available on demand service and self -provision. IAAS offers
cloud services via Dashboard or API that allows straight access over storage and servers with a
higher level of scalability.
Advantage:
 The core benefit is Regional Garden can automate their resource handling process as all
the resources and aspects will be managed and monitored by the service provider.
 Users have complete control over Virtual Machine and have the ability to construct their
personalized Virtual Machine.
 There is no need of any complicated setup and precarious planning to construct this
service as its applications are effective and simple in use.
Disadvantage:
 Regional garden has dissimilar systems and servers, it is challenging to coordinate IAAS
with different systems that also lead to unsynchronized server in maximum cases with
combination of different systems.
 It offers slight regulator over testing, deployment and upgrade methodology.
 Cloud provider will gain full access to customer’s data unless cryptography is used

PAAS
Platform as a Service provided automation functions are slightly different than IAAS that
mainly provides a platform to deploy and develop software. It enables the functional access over
the server interface and fundamental server hardware, which can assists the organization to
concentrate on more in organization’s side of scalability.
Benefits
 Very less management skills are required to use Virtual Machine as the service provider
will manage and monitor all the aspects and resources.
 While using PAAS, Integration will not lead to any conflict situation as different systems
are widely supported and can be customized.
 Clients can fully control and run its own virtual infrastructure without the maintenance
and invest in external hardware.
Issues
 The disadvantage is there will be less control over processing of data and on virtual
machine. Basically, organization will have no control and consciousness about their
resources and the processing methodology of data.
 In PAAS managing tasks could be time consuming and tedious also organization is in
charge to update and upgrade of new applications.

Difference
Infrastructure as a service comes with pre-configured systems as hypervisor hardware
however no optimal software interface is provided as operating system. While PAAS provides
high level applications which consist operating environment services (Kumar, Adlakha &
Mukherjee, 2016).
Database: IAAS allows the selections to select the necessary database as desired for high-,
distinct client information, security data or private code packing. While in PAAS this choices are
hard to customize.
Security: Using Infrastructure as a service third party security needs to implemented efficient
secure interface that also increase the cost investment. While in Platform as a service no third
party security applications are required as they provide optimal secure infrastructure.

PAAS
PAAS utilizes share point services in a hosted environment so staffs of Regional Garden Ltd. can
have their required configuration and will be not responsible for monitor and managing systems
they use. SSL technologies are suggested with SharePoint sites with a PAAS model. Typically
the SharePoint servers extensively situated exterior of the network boundaries and traffic must
pass over the internet. A third party hacker can easily gain access to the systems that could be
prohibit by using PAAS without minimal cost investment.
Advantage of PAAS
One of the main advantage of utilizing SharePoint in a PAAS platform is price efficiency.
Garden Regional Ltd. can have the choices to consume huge amount of functionality for a low
per-user monthly fee and there is no need of in-housing staff SharePoint in a PAAS. Maintaining
and update new patch is crucial for desktop and laptop servers. While using PAAS the
organization can maintain and update patches by their own that will surely save cost investment.
Problems that Regional Gardens may encounter
PAAS can be beneficial for Cost optimization and SharePoint deployment however there are
certain disadvantage to consider. PAAS clients uses multi tenancy as several customer shares
same application and that could leads to data loss, bad performance and possibility of open
server. By utilizing PAAS SharePoint services following types of information could be
compromised.
