CLOUD COMPUTING (ASSESSMENT 1)

Abstract
This research paper provides a literature review on the use of cloud computing in information
technology. Cloud computing is becoming the adaptable technology in the present scenario. It
provides the proper dynamic stability along with the use of services based on the resources
which are linking with the help of the internet. This paper includes the role of cloud computing
in the field which is based on the services of information technology. Cloud computing uses
some strategies that are internet or the servers based on the central remoting which can easily
maintain the security of the data and their applications. Cloud computing is computing
technology which generates IT resources by using technology based on internet technology. This
paper at the last provides the proper results which can be used in showing the cloud services or
the IT services.
Technologies involved in cloud computing

Cloud computing plays a critical role in the field of information technology. By using this
technology, the user can easily communicate with the multiple servers at a time and exchange
specific information to each other. Cloud computing exists with many technologies. They are
named as the:
 Virtualization easily
 Distributed storage
 Model for parallel programming
 Data management
 Services offered by cloud computing
1.Virtualization
It is the type of method which can be used to deploying the resources based on the computer. It
can easily separate the various levels based on the application system. Resources involved in the
application system are software, data, hardware, networking, server, physical devices, the
realization of the dynamic architecture or to achieving the goals to manage the centralization and
the involvement of the physical and virtual type of resources. This technology is used to improve
the system flexibility, decrement in the cost, many services are improved and the involvement of
the risk management in an easy manner.
Virtualization in the computing system is an away which can create the virtual version based on
the resources and the resources. For example, server, devices for storage, networks or the
operating system in which the entire framework can be divided into the one or more the
portioning for the one environment execution. The virtualization may be considered as hard
devices or derives. It is so because the portioning can be taken in the two different-different
drives. The virtual resources give allowance to the interaction with the devices, several
applications or the human users because they are the resources based on the real single logic.
2. Distribution storage
Cloud computing uses the technology which is commonly based on the distributing storage to
saving several amounts of data. This can be done to achieve and maintain the high economy
along with the credibility. It can easily provide ensure for the store data reliability and using the
software which is based on the high credibility of the hardware. That’s why it is known to
provide the cheap or the mass distribution to the storage or the computing system. The Hadoop
team develop the storage team which works on cloud computing are the GFS or the HDFS. GFS
stands for the system based on the Google file or HDFS stands for the system based on the
Hadoop distributed file system. GFS is considered as the system for file distribution and HDFS is
considered as the system for the file distribution which can run on the hardware commodity. It is
same as the existing system of the distributed file along with some significant difference.

3. Model for parallel programming
To provide the best facilities to users following the use of the resources based on the cloud
computing, it uses the model for map reducing programming. This model decomposes the single
task into several tasks. At large node scale, it uses two steps that are the map and reducing for
the realization of the scheduling. The map-reduce system is developed by Google which is the
parallel programming. It is used to put down the parallelism or the fault tolerance in the database
along with providing the load balance in the database. This system includes the three parts that
are defined as a master, worker or the client. In three of them, the client is mainly responsible for
the submission of the assignments based on parallel programming. This assignment is commonly
composed of the master nodes by the user. The one common feature of this task scheduling is the
scheduling priority which belongs to the data (A. M. Mansuri and P. Singh).
4. Data management
Data management technology is used for management of the data effectively. It is so because
cloud computing requires the processes and analysing the mass data. All the data items arranged
in the sequential order according to the keywords based on the dictionary. The data is arranged
dynamically in the row and then traverse to the tablets. There are mainly three ways which can
be used to store the information of the high locality to attain a high amount of scalability based
on the structure of the data. The proper management of the data based on cloud computing is
required due to managing the data from losing and taken its backup on a timely basis. Data
management saves the high-quality data in the storage part which can be used when servers are
not working properly.
Services offered in the cloud computing
Several services bed on cloud computing can exist with the different fields that are sector based
on IT education, online marketing, E-Commerce, the government organization, etc. The services
based on cloud computing can be generated in the several layers which starts from the hardware
system and moves to the applications based on the software. The responsibilities of the cloud can
be shifting several times to maintain the installation of the hardware systems along with the
instalment of the computational services which can be away from the customers and moves
towards the cloud vendor. These services can be provided to the make the better use of the cloud
computing in the Information technology or in the other networks. It provides the several
services which can used in proper functioning of the storage of the data and which provides the
proper requirement in maintain the data at the perfect level.

Recommendation
Some organizations are willing to implement the cloud computing. There are certain
recommendations which should be followed by the company.
Sign the contract yourself- Do not make the cloud providers directly interact with the clients.
Instead of direct interaction, the company should sign the contact themselves. By doing this, the
client will be using the certain cloud provider after the company’s recommendation.
Define your own requirements for technical and legal security- a company should make sure that
the customer needs and wants are satisfied; therefore, it is important to know that the following
points a company should consider-
Legal constraints- legal constraint contains location of data, guarantee of security and
confidentiality, specification for the different type of data.
A practical constraint- practical constraint considers the availability, reversibility and
profitability.
Technical constraints- technical constraints consider the interoperability with existing system.
The main risks identified in cloud computing are- loss of guidance regarding processing, highly
dependent on the supplier, error in the isolation of data.
These should be a proper solution for the above-mentioned risks. Once the solution is found,
cloud computing would be very easy to install for the companies.

Conclusion
This paper provides a brief description of cloud computing and the main services which are
offered by cloud in the field of the information technology field. It can be shown in this paper
that this technology is considered as the key technology for data storage or data management.
This paper provides the characteristics of the programming model. Cloud computing mainly
provides services like the calculation, services and their applications. This paper presents the
technologies based on cloud computing and its services. Cloud computing is like the computing
paradigm which can easily provide the services for the customers that are based on the server,
network, etc. These services demand less management. The success of cloud computing
commonly depends on the ability through which the promises of the cloud provides can be
effectively fulfilled to the users. This paper provides a proper description of the use of
technologies based on cloud computing in the information technology sector. The technologies
involve the programming models, data management, virtualization or the distributed storage
which show that how efficiently the cloud computing makes the applications perfect.
