Introduction
Network programmability can be defined as the usage of the software in order to deploy
and manage the network elements so that the trouble shooting can be performed in a more
effective way. It is basically driven by an intelligence software stack which is an action based
program performed on the request of the business and also on the request of network events as
well. Computer networks are defined as the network of the data and the series of interconnected
notes which generally transmits and receives the exchange of data in the form of voice and video
traffic. Servers and modems are the examples of these notes and it commonly helps the end point
users to share the resources and at a good communication level. Cloud computing refers to the
technology which helps in sharing and gaining the technical resources that involve the delivery
of the hosted services with the help of the internet. It provides services in basically three types
that is the infrastructure as a service and platform as a service along with the software as a
service. It is the on demand availability of the resources of the computer system in terms of data
storage and computing power. It has a function which is distributed over more than one location
and each location has the data centre for speedily and accurate rendering of resources (Claise,
Clarke and Lindblad, 2019). The following discussion is based on the cloud computing
impacting the industries and how the job role of network professionals evolved in order to meet
the technical challenges of the cloud. Moreover the current report also provides the insight of the
restful web services to facilitate changes and why the software of networking is so heavily
adapted by the industries. The report also views the standards while considering the
interoperability of different software selected with proper conclusion.
How the shift towards cloud computing has impacted the industry
There is a positive impact of cloud computing on the industry. Cost reduction is one of
the advantages gained by the industry. This is because cloud computing is a concept which
basically works upon the pay per use methodology. This reduces the expenses of the company
which also decreases the cost of labour and maintenance as well. Scalability is another advantage
gained by the industry. The customer is benefited with the scaling up and scaling down of the
resources as per the needs and requirements and can appeal for the services anytime and
anywhere. Flexibility is also one of the advantages gained by the industry. Customers are free to
make decisions about what services they want either without pain or with payment so that the
1

security needs can also be fully filled and other goals of the business as well (Municio, Latre and
Marquez-Barja, 2020). Cloud computing provides unlimited storage is also another advantage
gained by the industry. It provides unlimited storage up to the extent that it can fulfil the needs
and requirements of each and every business but it also has the limit after which it asks for the
payment. Disaster companies are one of the advantages gained by the industry in which it
provides securities services to the big data management which ultimately helps in reducing the
data reaches and losses. Cloud computing has changed the way of doing business because there
is no infrastructure needed while using the cloud computing which further helps in the computer
networks in the organisation so that the expansion can be easy for the company with the help of
cloud computing and computer networks collaboration and integration among them. Moreover,
there is no need to maintain the current upgrade cycle because the services of cloud computing
update on their own whenever they feel that the services are getting outdated. It helps in reducing
the end products which are smarter in nature which helps the businesses and industries to
maintain stability in the market place and good reputation in the industry while having the better
competitive advantage as well. It helps industries in utilising the technical resources in an
effective and efficient manner with the help of web based applications and internet. It renders the
information technology infrastructure in an advanced manager so that the emerging technology
can be adopted by the organisation. Furthermore it helps the industry in delivering the better
customer experience with more flexibility and better communication and teamwork. It has
changed the industry's structure in the form of reliable continuity and strong security with easier
mobility and automatic updates as well (Dou, Miao, Guo and Xia, 2021).
How the job role of network professionals has evolved to meet the technical
challenges of the cloud
There are various challenges of cloud computing which are recovered by the network
professionals. Such challenges are the security concerns. This is because there are various
organisations who store their big data in cloud computing and manages their password security
accordingly. But if the passwords are not strong then the hackers can crack and the data can be
breached and lost. Therefore security is one of the major challenges of cloud computing. Cost
management is also the challenge because of the lack of the expertise and the major requirement
of the indent connectivity all the time. Moreover control or governance is not in the hands of the
user because of the compliance and more than one cloud management used by the customers.

Creating a private cloud affects the performance of the services and also the migration from one
place to another (Dang, 2019). This also results in the interoperability and portability of services
provided by cloud computing. Reliability and high availability of the services are also lacking in
cloud computing if it is not managed in a proper way by the technical expertise. Complications
in the hybrid cloud are always the problem in performing the cloud computing technologies.
Therefore, it is important to evolve the job role of network professionals so that they can
overcome the challenges of cloud computing and computer networks so that the industries can
have a more positive impact on their functioning. Changing roles includes the changing abilities
to manage the capabilities of integrations and priority services of cloud computing. Information
Technology staff has developed the broad understanding of more than one tools which is built by
the third parties instead of indexing heavily on the supported technologies of specific vendors
information Technology expertise has shifted their focus from the hardware management to the
soft skills that the end-to-end abilities can be managed instead of engineering of the individual
steps. Information Technology professionals mainly target the security requirements and create
the different relationships among the vendors and the types of skills required to manage the
security of the cloud computing services. There are areas where the change can be seen are the
vendor relationships and the focus of the businesses along with the different technical skills and
many more (Vilalta, Casellas, Martínez and Muñoz, 2019).
How RESTful Web Services have been used to facilitate these changes
Restful Web services are defined as the architecture based Web services. This service
contains resources which are lightweight and highly scalable and maintainable. It is commonly
used in order to develop the API for web based applications. These are the services which are
important to minimise the coupling among the server components and client in a distributed
application. It facilitates the change discussed in the form of providing the skill ability and
flexibility along with the portability and independence. It is simple to adapt and build in a lower
cost and low use of resources as well. It has process instances which are formulated explicitly. It
contains the initial URI where the client does not need any routing information (Nascimento,
Ordonez and Ribeiro, 2019). It provides the generic listener interface for notifications to the
client. These are the web services which are used when there is a limited bandwidth and
resources. Moreover it is used when there are the easy needs and requirements of coding and the
availability of cache as well. It facilitates the changes while integrating in an easy manner and
3

also uses the hypertext transfer protocol in terms of scale ability and independence so that the
uniform interface can be used and rendering the layout system as well. These are the web
services which help in supporting all types of data formats and helps in working with web
browsers which also use less bandwidth and do not need to be designed from scratch which
makes it easy for most of the developers. It helps in simple binary application design and uses
the hypertext transfer protocol as a statelessness protocol and maintains the previous interactions
among the clients. It is based on the client server architecture with no conditions and catchy
enabled information as well. It has a consistent interface and the resources can be accessed by
name. All such features and advantages of restful Web services help in the change management
within the industry (Munoz, 2020).
Why software defined networking has become so heavily adapted by industry,
despite meaning an adaptation to the job role of network engineers.
Software defined networking refers to the approach of network management which
supports in the programmatically and dynamic networking in an efficient manner so that the
configuration can be done in order to improve the performance of network and monitoring of it
as well. It is similar to cloud computing. It is basically the approach of networking which uses
the controllers which are based on the software and the application programming interfaces in
order to communicate with the hardware infrastructure and also to manage the direct traffic on
the network. Software defined networking is highly and heavily adopted by the industry because
it has several advantages which are gained by the companies. It provides greater reliability with
the help of automation in complicated networks. It is time and cost efficient which helps the
company in creatively performing the activities in no errors (Atanasov, Trifonov, Vladislavov
and Pencheva, 2021). It provides more efficiency in network management because it offers a real
time visibility of the network performance so that it can be optimised at that point of time only
which helps in efficiency and effectiveness of the performance of the network used by the
organisation. Italy contributes to the cost savings and faster scalability in the company's
functioning and working. It provides rich customer experience by automatic and scaling up the
employee activities and productivity of the company. It has a major contribution in the content
delivery and that is why many industries have adopted the software defined networking because
nowadays attractive content attracts the customers towards the brand which helps in large sales
and revenue generations and loyalty from the customers towards the brand. It helps in
4

maintaining the long term relationship with customers with high productivity in the marketplace.
It helps in reducing the capital expenditure and provides centralisation management so that the
data server installed in the organisation can have the better security concerns with frequent
updates and password management. These are the reasons that software-defined networking has
become so heavily adopted by the industry despite adapting the job role of network engineer
(Rehman, Aguiar and Barraca, 2019).
Why standards, such as json and REST have been selected and utilised.
Specifically consider interoperability
JavaScript object notation is defined as the open standard file format which interchange is
the data format so that the human can read the text which is told and transmit the data objects
which contains the attribute and arrays. It is a widely used data format in terms of electronic data
interchange which basically uses the web applications with servers. It is generally used for the
text based format in order to represent the structure data based on JavaScript object syntax. It
provides the facilities to transmit the data in web applications in the form of sending some data
from the server to the client and it is displayed on the web page and vice versa. Representational
state transfer is an internet protocol which has a software architectural style introduced to direct
the design and development of the architecture over the internet. It basically defines the set of
constraints that states how the architecture is distributed among the hypermedia system and the
internet scale for example that how the web must behave (Cerroni, Galis, Shiomoto and Zhani,
2019. It is a server which transfers the representation into the requested resource the client.
JavaScript object notation is selected and utilised by several industries because it is a self
describing language. It helps in the interpretation of the applications and exactly represents the
data expected. It is selected and utilised because it is a simple text and compact in nature which
is also easy to learn and easy to understand along with the easy to read feature in it. It can be
expanded in the form of XML which has substantially lower character count which reduces the
overhead in the data transfers. It is easier to paraphrase and relevant in writing. It is a language
which is platform Independent and has the unified format which has the cause based on the data
volume. Its process is simple and takes up the least space which can be transferred in the text file
from the data structure. Another language which is text based formatting represents the
JavaScript object syntax. It is light weighted as compared to examine and passes the data quicker
with better ratio of data mark-up. Representational stage transfer provides a great deal of
5

flexibility that is why it is selected and utilised in various industries because it handles more than
one type of calls and different data formats. Moreover it manages the change in a structured
manner so that the correct implementation of hypermedia can be performed (Zhu, Wang, Xu and
Yang, 2021).
Conclusion
It is concluded that Network programmability is an important concept to learn and study
so that its applications can be applied in real world organisations. This is because it connects the
large range of computers with the help of modes and networks so that the information and
communication Technology can be adopted by the organisation for good interaction level within
the companies. Computer networking is highly necessary in today's world because it is
impossible for the organisations to survive without having the electronic communication as it
results in the expansion and multinational company’s growth as well. Therefore, it is important
to analyse the cloud computing which has impacted the industries and the job role of network
professionals in order to meet the technical challenges of the cloud. It is essential to examine the
web services which facilitate the changes. It is necessary to determine the reason behind software
networking being heavily adopted by the industry. It is significant to gain the knowledge about
different standards of different software’s used by the companies. Hence the above discussion
covers all such areas in order to better understand the conception of network programmability
and computer networks along with the cloud computing technologies.
