2.0 LITERATURE REVIEW
2.1 Literature review
Important source of a secondary data collection where a previous gap lies in the study
will get fulfilled in the research study. Similar or exact studies of scholars or authors utilize
as a benchmark in performing the literature review to meet the entire objectives (Zhang,
Deng, Liu and Zheng, 2018, pp.262-277). In this research thesis, ‘A’ rated previous research
published papers taken from authentic sources such as IEEE, ACM and ELSEVIER to ensure
the validity of the information used for this study. These sources consider as an important
source to give cent per cent assurance to the client about the high quality of the information
to be used in compiling the current dissertation.
Below mention literature review chapter of this dissertation will highlight several
concepts of cloud computing and infrastructure as a service as one of a platform of this tool.
Secondly, the study also explains the scheduling technique in the Infrastructure as a service
and to test its efficiency by analysing all the techniques using several parameters to the
research. Majority of people do not know about cloud computing so this study will contribute
to adding value for all the users in getting a new learning experience about this concept
(Muhammad, Alhamid, Alsulaiman and Gupta, 2018, pp.60-65). The concept of IAAS is also

11
new for the non-technical users as this study targets the entire technical as well as the
technical users in knowing about these terms in detail.
2.1.1 Determine the concept of IAAS in cloud computing
(Stergiou, Psannis, Kim and Gupta, 2018, pp.964-975), has asserted that cloud
computing is consider as a latest IT tool to offer reliable services to all the users. The problem
of data confidentiality will get eliminated due to the emergence of this system. In this system,
a user will store its information using the internet as data will store in the clouds to avoid its
stealing and will, in turn, increases the quality of the data. With the introduction of this
concept, this has increased the recognition of the entire information technology environment
among the external market. The exciting things about this system that it is very cost efficient
as a user will only pay on a pay per click as they will not get charged for installing the
software. This allows all the users to access the software’s remotely from any locations to
complete their work in less time as compared to other modes which are very expensive and
requires more time in accessing the information.
Secondary the aspect of this research study is infrastructure as a service as one of an
important tool of cloud computing. This kind of cloud computing eliminates the biggest
problem faces by a user in installing the software such as MS The project, MS office,
Architectural suites in accomplishing their work (Varghese and Buyya, 2018, pp.849-861).
To eradicate all these issues, infrastructure as a service concept introduces as a tool of cloud
computing to provide infrastructure in the form of software. Under this concept, an individual
will pay for the infrastructure they want to use and then remotely access the software’s on
their screen without purchasing the same (Shaik and Baskiyar, 2018, pp. 202-207). This will
minimize the overall risks such as errors in the software’s faces by a user after taking the
license of a system, complicated licenses, and expensive software’s. All these risks will
overcome by this mode by introducing a unique opportunity.
Different packages offer by the cloud computing services companies consisting of a
public, private and hybrid network that differ according to the nature of work, costing and
confidentiality and the storage requirements (Khan, Rehman, Al-Khatib, Anwar and Alam,
2018, ). Companies such as Microsoft and Google offer his cloud computing in which a user
will get the login credentials to access the information along with the virtual storage drive in
the clouds server that is through the help of internet. The system requirements such as

12
software and hardware requirements will control by a user in this mode as this is a virtual
system that allows all the users in fulfilling their requirements.
2.2.2 Explore the efficient workflow scheduling in IAAS in cloud computing
According to the view of Nunes, Roque, Araújo and Pereira 2018,), that says that the
round-robin scheduling method utilizes a technique to properly allocate the time to all the
activities. This method is termed as resource allocation method helps in allocating
appropriate resources to all the users to meet the requirements in a stipulated time. To survive
in the external environment, it is essential for an entity to understand the importance of the
time for which this process is used to meet the project objectives within a given time period.
(Kadri and Boctor, 2018, pp.454-462), says that genetic Algorithm uses by an individual in
the infrastructure as a service for task scheduling as the workload gets reduces by applying
this technique. By scheduling the overall tasks, it will get easy for a user to access the
information stored from the cloud to the virtual machine. Admin department will track the
usage of the information stored on the clouds using this algorithm in knowing the
decentralization of a project into tasks. It is considered as an output of progressive growth of
artificial intelligence.
As per the viewpoint of (Li, Ge, Hu, Song, Hu and Luo, 2018, ), that observes that the
minimum execution time algorithm is a unique way of task scheduling approach whose main
motive is to reduce the execution time in the cloud computing processes. Execution strategy
develops by an entity to keep track of all the project activities to accomplish all the activities
of a project in a stipulated time period. The motive of this algorithm is to reduce the makes
pan, costs and increase the resource utilization frequency to maintain the quality of the data.
(Ziaeinejad and Mehrizi-Sani, 2019, pp.4166-4176), has asserted that the switching
algorithm allows a user to switch from the data centre to another in case of network errors or
bug lies in one virtual machine. As using this way, the loopholes lie in one machine will not
affect other virtual machines and a user will continue to access the information without any
kind of hindrances. This will allow a user to switch from one task to another without starting
the whole process from the beginning as they also easily terminate the tasks in case of no
need.
According to the view of (Rasheed, et al., 2019, pp.23990-24006), that says that the
opportunistic load balancing system under which the workload of one server will shift to the
