Abstract
This paper describes about the future scope of cloud networking. It gives an overview of
the cloud networking giving the various features that come about by a device, the actual state of
the art technique that has been used in this way to achieve various possibilities. The general level
of development for a device, technique or scientific field that has achieved a lot is referred to as
state of the art. The level of development is made as a result of utilizing the available resources
and employing common methodologies to reach the expected achievement. Additionally, state of
the art implies that the particular level achieved is at a specific time. The term has been used for
so many years and has become common in some fields like advertising, marketing, and
communication.

Introduction
When something is being described as a state of the art, it means that it has been made
using the current technology and techniques and therefore, it is the best. Technology has been
advancing over the years, and this has enabled state of the art to improve in specific fields. In this
essay, some areas like cloud networking have been impacted by state of the art and it is widely
analyzed. Improved internet access enabled the pushing of net administration tasks to the cloud.
Internet-based access technologies and Wide Area Networking (WAN) are the commonly used
technologies by the network providers. The wireless LAN was the first market to make use of
cloud distributed networks. Hence, the cloud-based approach to building private networks
requires WAN and LAN connections. Cloud networking can be considered as a solution that
offers a combination of cloud computing and virtual networking. The answer to driving more
deeply the cloud computing into the network infrastructure is provided by cloud networking.
Cloud networking arguably is a type of technology that for a long time, has been in various
discussions and the introduction will make everything a little bit easier. This is a plus to the
various network vendors who, in all perspectives, require always to deliver better and better
services.
This technology shows numerous advancements that are required to be able to make
certain issues simple. This, in a way, is to be able to increase network access to different places
giving out the best in every situation. Technology as a whole is on another level making more
and more innovations to come in all aspects. In the study, there are various ways put across that
show exactly how the cloud networking technology will be able to ensure that the future of cloud
networking is safeguarded like Virtual machine migrations and so many more devices that
require advanced technology.

State of the art in cloud networking
Cloud computing services have provided the necessary software to ensure that there is
improved internet access by managing and controlling networks. Here we review the condition
of art used in the implementation of cloud computing, and therefore, the first thing is to describe
the technologies used. It can be said as a type of infrastructure where based on the demand; the
networking capabilities are available through a third-party service provider that hosts them on a
cloud platform. It is just more than cloud computing which entails a shift of even data over the
network.
Architectural scheme of the data centers
An information center is a house where computations, power, and storage take place.
Therefore, planning in an advanced way of the architecture of networks is critical because it
influences the performance of the application. The best method is using an approach that
contains layers that start of the architectural design of the network. There are three layers; access,
core, and aggregation layers. The layer used for access arrangers the servers in racks in such a
way that they connect to the network physically. There are about20-40 servers in each frame and
all are linked to control with a speed of 1 gigabyte per second. Aggregation layer provides useful
functions like location and domain services and also maintains the balancing of the servers. The
core layer provides the possibility for connectivity of sheets to man’s controls. It ensures
perfection. Additionally, a core sheet has routers that control data traffic moving through the
center.
As already established, networks are usually made up of Ethernet controls and WI-FI
devices that make up an infrastructure of networks. There are conditions to be met to design a

data center network as required by the current technology state of the art. The diagram
representing cloud networking is shown below.
Resiliency
Failures are common in the cloud network. The infrastructure must be able to tolerate
failures like connection outages and server-rack failures. Additionally, the system structure
should have the capacity to scale many giving rooms for expansion that are in continuous
increment.
Constant high capacity
The connection between servers has net border cards that limit traffic flow, and only the
required maximum rate of the connections flow is allowed. The communication of servers
depends on the topology of the network hence making it easy to allocate many servers to a task
(Guo et al. 2009).

Regressive compatibility
The state present makes it possible for the net structure to be compatible with backward switches
and routers running IPs and Ethernets. No improvements are needed to leverage commodity
Ethernet and IP in the available data centers. One of the significant technological advances that
are notable so far is the development of cloud networking; it is a way of interconnecting several
computers such that they process together and share data.
Software-defined WAN
The cloud networking uses some concepts from which few management devices are installed
where the clients want them, for instance, offices and premises. Additionally, more management
functions and routing are taken to the cloud through pushing. Cloud networks are on the look to
offer products that deal with networking.
In this era, whereby the generation is highly dependent on information, it is fortunate that we all
depend primarily on communication. Our methods of communication have been evolving over
the years; hence, changing the way data is passed. In today’s world, there is a need to stay
competitive, and information plays a vital role in ensuring that it is achieved. It is essential to
provide vast amounts of information to ensure that we progress. The great need for information
has led to advancements in technology, and this brings the world closer. That means long
distances have been made shorter and therefore, we can travel to places that are remote faster.
These advances in technology have enabled us to put the whole world at our fingertips.
History of networks
The most intriguing part is that connecting networks began 20 years ago as a test. It
began when the US Defense tried to build a communication department that would withstand
CLOUD NETWORKING
7
catastrophes, and its functioning is not interfered with, the first step was to establish a network
that they called the ARPAnet. The communication was supposed to occur between two
computers in the ARPAnet model. It was made of two parts; the source (local terminal) and
destination (remote terminal) and each end required minimum information. If any message was
supposed to be sent through the network, one was to put data into an envelope known as the IP
packet. A button was required to propel it to the target through an address.
Using the packet switching method, the tow terminals which were made of the source and
destination computers played the role of ensuring that the packet got from one end to the other.
However, people had no confidence in the network, and it was termed as unreliable. This is
because any portion of the system could disappear with no notice and computers can work
appropriately with others as pier or levee. That was the idea beyond the construction of the
network of computers. In cases where some part was unavailable between the source and the
destination computers.
For universities that did not own a standard set of computers, this was an attractive idea
for them, and they needed to adopt it as soon as possible. They could use all the sets of
computers, interconnect them and share files, data, programs, and electronic mail was possible.
As time went by, technology advanced and evolved, and the prices of computers dropped. Using
state of the art, manufacturers started putting TCP/IP protocol into the machines they
manufactured. What followed next is institutions, primarily that dealt with research began
adopting the protocol and linked their computer together. The new model was also approved by
libraries and large corporations. All institutions began taking advantage of the fact that there was
a high demand created by the communication standard. Since then, the internet has been growing
at a faster rate without stopping.

The internet has advanced over the years again, thanks to state of the art. Unlike the networks
used before, whereby the information was moved from one computer to another with no
organization, there has been the introduction of routers.
After that, the data is sent to other routers in repetitive processes until it reaches the final
destination. State of the art has also ensured that the router can know the specific computer from
which the data is being transferred to, just like in the old network model, where the data was put
in a particular packet, addressed and send, the internet assigns a unique address to each computer
in a network. The future of state of the art has a lot of hopes, especially with the continuously
changing technology.
People are already taking advantage of the lifelong network to learn through interaction
with other people from all over the world. The learning platform will continue to increase, and a
strong bond will be created between different learners in different parts of the world. The
learning platform has built opportunities for collaborative project work that will see learners
unleash their full potentials. While people realize what they are capable of harnessing and
learning new skills will be achieved through the knowledge gained from the global cohort.
State of the art is not the same in all countries. Some nations are blessed to have more skills
and improved technology than others. Cloud networking makes it possible for people from
different countries to learn from each other. Hence, this increases the cultural diversity, and
people can learn a new culture from others. The transfer of learning can result in the emergence
of a bunch of professionals from diverse countries, industries, and functions. The already
growing network enables interested learners to interact with corporate partners and to rank
academicians who can enrich a person both personally and professionally. As people become

more knowledgeable, new skills are developed that will be used to improve the state of the art.
New computers will be manufactured with improvements that will make internet access easier.
Cloud networking also has a bright future, as many countries are adopting improved network
models. Sometimes back, people could only access the internet using computers just. As already
established, technology is the platform behind every state of art improvements. Another
development in cloud networking is the automated service provisioning. In this feature, cloud
networks can release inadequate resources. The primary function of the service supplier is
resource allocation, then de-allocation from the cloud to satisfy its (SLOs). However, the
operating costs have to be reduced even though there are resource requirements for the type of
computers involved. However, it is hard to predict how to plot SLOs like memory and CPU
necessities and that is an improvement that has to be performed soon. Since the automatic service
provisioning is a known problem, solutions are underway and some of the propositions are:

Construction of an application presentation model which will be predicting occurrences
that require to manage demand given levels as far as the application is concerned

Since technology changes every day, it is essential to predict future demand and
determine the resources required using the performance model (Zhang Q et al. 2007).
This should be done periodically

Allocating resources by use of the predicted resource requirements which should be done
automatically
There are ways that will ensure that the future of cloud networking is safeguarded like
Virtual machine migrations (VMs). There is a system of live migration of VMs, which was
developed by Xen and VMware and has already been implemented (Mysore R et al. 2009). The
new VMs involve downtimes that are extremely short and range from milliseconds to a second.

Many difficulties faced by process level migration can be solved through migrating the whole
operating systems (OS’s) and all of its applications both as a common unit. The major
importance of VM is avoiding hotspots. However, during the OS migration, the memory of all
machines has to be efficiently and consistently transferred, considering that the application
resources and physical servers remain constant.
However, there is the old generation that has not yet familiarized itself with the current cloud
systems. As the world is becoming digital and the past age is being replaced by the digital one,
the new generation will be in total familiarization with the internet. Nonetheless, for
improvement in cloud networking, then state of the art will need development through
advancement in technology.
Technology affects the choices a person makes when making purchase recommendations
for a customer. In recent years, most companies and organizations provided customer services
through emails. Unfortunately, the client queries by the clients were ignored and failed to receive
immediate replies and calls. (Musso & Druica, 2014). The available communication channels
had challenges, and they only favored the company more. They were discrete with the
information given out about their products.
Things have been refreshed in this age, whereby social media platforms have reduced the
distance between the customer and the producers. It is not possible to sacrifice a customer to
maintain a brand position. Things are different now because failure to respond to a customer’s
query will jeopardize the reputation of the brand. The conversations and information are
available to millions of people courtesy of the cloud network (internet).

So many things around the world will change and so many narratives will change in the
introduction of the technology. What used to happen before will change for the better as the
technology will prove so much more powerful capabilities as compared to many previous ones.
The technology will influence the choice of purchase because the consumer expectations about
goods and services have changed. This is because the company had set that all the clients were
set for business. However, technology has changed everything, especially after the invention of
electronic business and phones. People can reach the products of the company anytime. As an
organization, you must be racing with consumer behavior changes or fail in business (Musso &
Druica, 2014).
In my opinion, cloud networking has been improved by technology improvements that
influence connectivity, bringing people from all over the world together. The trend is not
anywhere near changing since from the introduction of smartphones to the use of fast data, small
children as young as five years can use and access the internet.
