INTRODUCTION
There are phenomenal changes and growth can be seen in Computing
services in recent years.
For many firms there was great requirement of such things to reduce their
capital, maintenance and operating cost.
Moreover, they require more comfort ability in dynamic scaling and
adopting new services without affecting the existing organizational
structure.
Though, IT resources were there for managing the organizational work,
however, after cloud computing they were able to perform more better
function and had improved performance.

Issues faced by organisations in providing
scalable, flexible, highly available computing
resources.
Firms required to integrate cloud computing into IT strategy and processes
so that they their improve their data and information governance programs.
The central part is played by Data centres where various servers are
collected and application are placed and accessed using internet.
Cloud computing has three service models these are SaaS, PaaS and IaaS.
SaaS stands for Software as a service, where there is need of network,
operating system and Software.
In organisations it is mostly used because it reduces the complexity of
networks, there is no need of software licence.

Evaluate technologies that can
address these problems
In grid system there were many problems such as they were not reliable
and does not provide quality of services (Zhang, 2016).
Moreover, those devices were unable to provide the broad network access,
measured services, on-demand self-services, resources planning, rapid
elasticity and measured services.
Cloud-based computational technology is one of the best technologies that
help people to overcome all the issues they face at the time of cloud based
computing.
Among the noteworthy benefits these are most common that makes it
greater than other software and hardware:
It is cost saving and effective method of preserving the data.
There is higher flexibility and person can have remote access to its work.
The application has more resilience and offer services without redundancy.

Propose and justify solutions using
appropriate technologies
In past as people have to use many software and hardware now technology
has changed and now people have to use the applications that are simple, cost
effective and reliable so that people can have trust over using them.
However, there are challenges faced in cloud computing when it is about the
business and its facility.
Extensibility
Security
Cost Effective
In 2015, an estimation was made for the UK businesses that many people
were using the Cloud computing or cloud services.
Collaboration, Allows To Work Remotely, Flexibility, Work from anywhere
and increased collaboration, Disaster recovery, Automatic software updates,
Capital-expenditure Free, Document control, Security.

Cloud computing
A number of characteristics define cloud data, applications services and
infrastructure:
Remotely hosted: Services or data are hosted on remote infrastructure.
Ubiquitous: Services or data are available from anywhere.
Commodified: The result is a utility computing model similar to traditional
that of traditional utilities, like gas and electricity - you pay for what you
would want.
Further, it use in Amazon is explained

Amazon Simple Storage Service
(S3)
Amazon provides Unlimited Storage.
Person has to pay for what you use: $0.20 per GByte of data transferred,
$0.15 per GByte-Month for storage used, Second Life Update: 1TBytes,
40,000 downloads in 24 hours - $200.
Further, it has Amazon Elastic Compute Cloud (EC2):Elastic, marshal 1 to
100+ PCs via WS,
Machine Specs…,
Fairly cheap!
Powered by Xen – a Virtual Machine:
Different from Vmware and VPC as uses “para-virtualization” where the guest OS is modified to use
special hyper-calls:
Hardware contributions by Intel (VT-x/Vanderpool) and AMD (AMD-V).
Supports “Live Migration” of a virtual machine between hosts.
Linux, Windows, OpenSolaris

Advantages of Cloud Computing
Lower computer costs:
High-powered and high-priced computer to run cloud computing's web-
based applications.
Since applications run in the cloud, not on the desktop PC, your desktop
PC does not need the processing power or hard disk space demanded by
traditional desktop software.
When you are using web-based applications, your PC can be less
expensive, with a smaller hard disk, less memory, more efficient
processor.

Cont.
Improved performance:
With few large programs hogging your computer's memory, you will see
better performance from your PC.
Computers in a cloud computing system boot and run faster because they
have fewer programs and processes loaded into memory.
Reduced software costs:
Instead of purchasing expensive software applications, you can get most
of what you need for free-ish!
Most cloud computing applications today, such as the Google Docs
suite.
Better than paying for similar commercial software which alone may be
justification for switching to cloud applications.
Document Page
Cont.
Instant software updates:
Another advantage to cloud computing is that you are no longer faced
with choosing between obsolete software and high upgrade costs.
When the application is web-based, updates happen automatically
available the next time you log into the cloud.
Improved document format compatibility.
You do not have to worry about the documents you create on your
machine being compatible with other users' applications or OSes
There are potentially no format incompatibilities when everyone is
sharing documents and applications in the cloud.

Critically evaluate the application of
solutions using the technologies, to the
problems
As per the Julfathna, Babu and Jayakameswaraiah (2014), critical issues
that are associated with cloud solutions is data security. There is major
issues over this topic which is based on the 4 components, these are
availability, integrity, confidentiality, and traceability.
Karadsheh and Alhawari, (2011), have stated that cloud-based service
supplier has been the major and a serious security risk issues.
Many firms have adopted that cloud services have provided them path
through which they have raised their level and standards. Such
technologies are really going to enhance the business areas and
profitability of the company.

CONCLUSION
Changes can be seen in this global world, so are changes adopted by
organization.
The use of cloud is a profound evolution that can be seen over the computing
industry.
There are are various revolutionary implications for business and society that
can be seen using the cloud computing.
It has created new possibilities and enabled more efficient, flexible and
collaborative computing models.
Now business professionals have to use the technologies that are adopt the
tendency to measure and utilize value-added cloud solutions.
