Section 2
Approach to Automation
Automation has been a technology that has been ever growing since the last decade. The
global acceptance of the technology has forced increase the growth in usage of automation. Two
strategic approaches that are technically efficient for testing the automation are as follows: -
 Keyword Driven Testing Framework.
 Hybrid Testing Framework.
Keyword Driven Testing Framework
Keyword-driven testing is a standardized automation technique used for functional
testing of the automation framework or specific word accessed testing. In Keyword-driven
testing, a table format is being used. Spreadsheets are mainly used to approach the testing of the
automation infrastructure and the specific function is used to perform actions that are to be
executed (Lewis, 2016).
Benefits of using the Keyword Driven Testing Framework
The advantages of Keyword driven testing framework are it is easy to create a Key word
driven test, applying key word driven test to the testing of the automation is faster and easier than
the testing of the entire scripts, providing efficiency to the testing approach. The other
advantages are creating automated tests are much easier with the key word driven testing
infrastructure and creating test batches that are automated in nature utilizing the logic generated
during the key word driven test.

Issues related to Key word driven test
The main issues of Keyword driven test are that different result are viewed in case of
accessing of the automation through different browsers.
Hybrid testing framework
Hybrid testing of the automated infrastructure is a type of testing that increases the
efficiency of the framework over the time (Peng, Huang&Husain, 2017). This proficiency of the
testing methodology gains importance as the information are checked using the referenced
information that are previously stored in the system.
Benefits
The main benefits of Hybrid testing framework are reusability of the framework,
adaptability of the hybrid testing framework has been used as its speciality as usage of this kind
of framework is easier than other frameworks (Wu & Wang, 2014).
Issues
The main issues of Hybrid testing framework are high infrastructure complexity is the
only major issue of the hybrid testing framework, the testing of the framework requires skilled
and educated stuffs which is difficult to find as a labourer.
Recommendation
Hybrid Testing Infrastructure is the recommended way for automation in Regional
Gardening ltd as this automation testing framework is most successful in nature has the
ac1commodation of testing of the grammatical error as well as the perfection level of the
spellings being used in the project including the information unit. Another reason to recommend
hybrid testing framework is the readability of the framework is easier than the other networking

frameworks, the maintenance of the entire system is easier than most of the testing frameworks.
This framework does not face issues like Selenium tests often fails, no alteration in the process
can be implemented in case of Keyword testing process, and in case of open system sources
documentation of the project poses least accuracy in the automated.
Section 3
Difference between IaaS and PaaS
Cloud Computing has been gaining global acceptance in today’s society.
The differences between the infrastructure of IaaS and PaaS are as follows: -
 IaaS is claimed to be a built it yourself infrastructural approach. With the aspect of
infrastructural approach makes the list of Amazon web services and the platform oriented
application, each personnel might have access to the integrated and specific set of tools.
These tools helps in developing applications and helps in managing the procedural
application. Whereas in case of Platform as a Service, it provides the complete
development package that is the specific platform oriented application (Yamato, 2017).
 Information at a Service is considered to be a low level infrastructure, whereas in case of
Platform as a Service is considered to be a medium to high level infrastructure.
 Infrastructure as a Service is considered to be a tool that is required for developing an
service oriented application that will be dependent on the cloud computing platform
where as in case of Platform as a Service is considered to be a tool that is utilized for
maintaining and supporting the preconfigured tool that is dependent on the cloud
computing platform (Kavis, 2014).

 During the usage of Infrastructure as a Service the developer who has been linked with
the managing of the infrastructure of IaaS needs to manage the execution of the entire
process and maintain the entire data base of the operating system of the cloud based
platform, whereas in case of Platform as a Service can be automatically connected with
the fully serviced gas stations relayed with the application development managing
services.
 In case of Infrastructure as a Service the entire infrastructure needs to be built and no
instance of previously built infrastructure can be used, leading to the fact that the
infrastructure is built specifically for the distinct infrastructure and is configured to its
specific configuration, whereas in case of Platform as a Service the quadrature of the
infrastructure is assembled together in order to get the infrastructure getting completely
structured. The assembling of the quadrants are the way of creating a PaaS infrastructure.
 The basic layers of cloud computing is useful for the administration of the Infrastructure
as a Service whereas in case of Platform as a Service middle layer of the cloud computing
enables the development of the infrastructure of the cloud computing platform.
 Access to the IaaS requires a lot of knowledge regarding the performance of the IaaS
infrastructure as due to the lack of robustness in the platform, the infrastructure is able to
support further development in the infrastructure for specified task whereas in case of
PaaS the knowledge of coding must be present in the core requirment of the employment
of the aspired employees (Crago & Walters, 2015).
 Ciska, Metapod are the few examples of IaaS where as Apperanda and Heroku are few
examples of PaaS

Model Selection
Cloud Computing has been gaining global acceptance and the technology has been ever
evolving in nature. The cloud computing infrastructure is subdivided into 3 broad categories
namely: -
 IaaS
 PaaS
 SaaS

Recommendations
Infrastructure as a Service is the most recommended infrastructure for the Regional
Gardening Limited.
Advantages of Infrastructure as a Service for Regional Gardening limited
 Cost saving
The most exciting benefit of Infrastructure as a Service is the fact that the setting up of the
infrastructure is very low and the lowest among the other infrastructures of the cloud computing
systems including the likes of the Platform as a Service and Software as a Service (Ferrer &
Lastra, 2017).

9CLOUD COMPUTING
 Scalability and flexibility
Ability of scaling up of the IaaS is one of the most exciting feature of this cloud based
infrastructure. IaaS is powered with the largest storage system and powerful servers and
networking which acts decisive in completing the needs of the clients (Zhang, et al 2017).
Issues and recommendations
Privacy of the infrastructure is not robust as it should be. To overcome this issue one must
ensure the infrastructure is not needed for the Infrastructure as a Service for the Regional
Gardening ltd. Technically very complex in nature incase of IaaS. To overcome this issue one
must install the IaaS the company is free from maintaining the infrastructure and the
infrastructure of the previous set up is no longer the liability of the organization. High
dependency on vendor lock in. To overcome this problem ne must provides the infrastructure
related to the flexibility which provides greater agility to the product, leading to the ability of
responding to the ever changing technology that is constantly evolving.
