This report is designed to develop understanding about the cloud computing software. Its name is derived from the idiom of “cloud”, which originated from the world of telecommunication. It offers usage of VPN (virtual private network) services for data connection to people. This report will focus on the impact of the cloud computing on business sectors. This report also focuses on the characteristics of the cloud computing software. At the same time, this report also focuses on the advantages or disadvantages of the cloud computing hardware and software. This report also focuses on the importance of the cloud computing for the business. This report also provides discussion on the different types of a model of cloud computing such as IAAS, PAAS and the SAAS.
According to Marston et al. (2011), the cloud computing is the example of a new computational method, which presents the inventive company’s model for industries to accept the information technology. Although, the prospective benefits accomplished through the cloud computing and the security of model are still questionable that affects the adoption of the cloud model. On the other hand, Low et al. (2011) explains that under the cloud model, the problem of security has become further complicated issue. The scopes of cloud computing covers different concepts such as multi-tendency, elasticity, and model architecture or layers dependency stack.
There are five types of characteristics, which are associated with the cloud computing such as network access in the broader manner, rapid elasticity, on-demand self-service, resource pooling and measured services. The detail of these characteristics is as below:
Network Access in Broader Manner: According to Zissis and Lekkas (2012), the cloud computing has offered various kinds of networks, which could be accessed by using standards mechanisms and encourages the custom with heterogeneous wide and thin client platforms such as mobile phones, PDAs, laptops etc.
Rapid Elasticity: As per the views of Armbrust et al. (2010), business clients have provisions to utilize unconstrained computing sources that could be obtained by anytime and in any number. At the same time, Marston et al. (2011) exclaim that the consumers have provisioned to use the unconstrained computing resources that have been obtained by few places.
On-demand Self-service: According to Foster et al. (2008), business clients and consumer on one-sided origin have capability of computing such as server time or network storage that have automatically vital devoid the human communication with each of the service contributors.
Resource Pooling: The cloud computing has pooled resources, which give the services towards the numerous consumers. It helps various models by physical or virtual team that have assigned and reassigned the factors like demands of clients and consumers.
Measured Services: In views of Foster et al. (2008), the cloud computing mostly controls and renovates the sources as per the given services or leverage capabilities. The features of cloud computing also consist of bandwidths, storage, and processing.
According to Xu (2012), Cloud computing refers to a way in the companies, in which board or management manages the online computing sources. Idiom of cloud computing has merged and developed in more advanced manner in current years. The cloud computing can be utilized in order to allow multiple persons to use the same database, and computing features at same time. The ‘cloud’ computing requires the internet for operating ‘in the cloud’ that explains the method of the store and approaches its data from internet connection. On the other hand, Foster et al. (2008) assert that cloud computing permits the organizations to access their information virtually and building the elastic or global key of accessing the company data anytime and anywhere.
Cloud computing is the computing of network, which works on the large scale. The cloud computing offers different benefits to the business firms such as faster communication, ease of access and secure collaboration.
Faster Communication: Zhang et al. (2010) say that cloud computing technology recommends improved or reasonable communication to business entities. The faster communication can help business firms in more ways like decentralizing of business, that becoming growly famous for a lot of organizations. In faster communication, the cloud computing tool offers exploited tendency in providing reliable as well as cost-effective IP-based connections.
In an organization, the faster communication is the important part of the cloud computing. Company’s managers and employees can easily process, communicate and coordinate key business database. As per the views of Armbrust et al. (2010), there are different parts of cloud computing model such as caller ID, forwarding, parking, blocking, and free calling between staff members and built- in call screening etc.
Ease of Access: Cloud computing provides the faster internet connection for all the business. Cloud computing provides the easy access of data, crucial business software as well as projects from any location into the whole world. Business professionals do not need to install and keep the software and any kind of special application for a long time in the laptop and tablet, as the cloud computing has replaced this need.
Secure Collaboration: According to Armbrust et al. (2009), secure collaboration is the biggest feature of cloud computing. The cloud computing provides the faster, dependable and easy collaboration for company’s group members from everywhere in the whole world. Cloud files could be accessed at any time, and by any group member of the company.
Benefits of Webb’s Stores:
The cloud computing offers different types of benefits to Webb’s store such as:
Reduced Costs: This technology attributes to reduction in overall costs for the companies. This way, the adoption of cloud computing in business can maximize profitability of company.
Flexibility: Flexibility is another feature of cloud based computer networks. Cloud computing has enabled the companies to inter-link their different offices to work on same platform irrespective of geographical distances.
Increased Storage: The high level of storage capacity is another feature of the cloud computing platforms. There is no need for the company to purchase storage devices for storage of their business database. The companies can simply keep their raw and processed database on cloud storage platform. This way, key company data are safe from unfortunate incidents like computer corrupt problem, virus problem, hacking and malware practices etc.
AWS/ Azure used for the business integration of Webb’s Stores:
AWS (Amazon service of Web): It offers cloud computing services on demand from clients.
Azure Webb’s store: It gives different kinds of service like PAAS, ASSA or IAAS.
There are various types of combinations such as:
According to Zhang et al. (2010), Azure and AWS both are important services of cloud computing which gives the different types of model for computing such as IAAS, SAAS or IAAS. These have provided the fast processes or placement services in order to integrate the new stores by the operation of existing features. These also enabled all business firms to increase the retry, feedback, and test functions according to company requirements. It is not dependent on the locations as well as can transform presentations according to the use and performance changes. The application of studio Visual has also given the adequate business environment, which helps in order to integrate facts and information according to tasks. It has given the disaster recovery or in-built failover capabilities towards the business, which provides the numerous replacements in order to organize the processes. On the other hand, Calheiros et al. (2011) also observed that the organizational privacy, as well as the privacy of key users is protected by cloud computing platforms. Apart from this, companies are also capable of organizing data centers from any location. A cloud computing platform uses the single model by efficient source allocation.
Software- as – a- services (SAAS): Highly scalable application, which is based on the internet. It offers the services to various ends consumers.
Platform – as – a- services (PAAS): On cloud infrastructure, the development, test or design, Test that is based on it.
Infrastructure – as- a – services (IAAS): It makes availability of the different types of services such as storage, database management and computing capability.
(Source: Candrlic, 2013)
According to Armbrust et al. (2009), SAAS model of cloud computing has provided an application based on the demand of various clients. It has made available the application and services in such a way, which could recommend the services and its relevance to different consumers. It has single application to reduce the costs. On the other hand, Xu (2012) has provided that the PAAS provides the location feature also so that huge level and services could be simply assembled. In PAAS model, companies are provided the freedom to create their own application, which could be, offering services running for infrastructure. It has also given the mutual platform of application server or Os, which helps in order to supervise or scale requirements for the operation of organization. At the same time, IAAS has given the storage or computing capabilities as per standards of sustained services in network. The IAAS has given the servers, storage system, networking equipments or data centers that have assembled mutually to handle the workload of organization. In this, clients have capability of organizing their personal applications and software in more effective manner.
Easy Management: As per the views of Rimal (2009), the infrastructure has to be maintained to use the cloud computing software. In the views of Foster et al. (2008), it is also an application, which has quit storage extensive, is huge easier when individuals uses business. For the client’s level, it is mainly required to the simple web browser by the connectivity of the internet.
Uninterrupted Services: The cloud computing services offers the inferior outages. Hence, it has offered the uninterrupted towards the clients. Through, the few occurrences of outages are arising during the previous such the Gmail outage in the year of 2009.
Cost Reducing: According to Zissis, and Lekkas, (2012), Cost reduction is one of the major advantages of cloud computing as well as it is main advantage for SMEs. The cloud computing has significantly decreased the informational technology spending for SMEs. Most of the times, it has also given the quite reliability during the terms of availability that is a clear winner.
Green Computing: According to Rimal et al. (2009), in business, the harmful emission is faced due to extensive use of the cloud computing system. On the other hand Armbrust (2009) has exclaimed that the e-waste has become the negative side of cloud based computing mechanism.
Disaster Management: As per the views of Zhang et al. (2010), in case of disaster management, the outside backup of software is always helpful for the consumers. For most of the businesses, maintaining the data of crucial backed up, is very important, which is provided by cloud service providers. The cloud storage services have not only maintained the offside data but also have ensured the system within the place for recover of data from disaster.
There are six main disadvantages of cloud computing. These disadvantages are:
Downtime: According to Zissis and Lekkas (2012), downtime is the worst disadvantage of cloud computing. No one can immune the best services to the system, as the cloud computing is fully based on internet connection, which implies fully dependency on the internet connection. Any of the reason, technical failure or internet failure can be held responsible for the failure of cloud platforms.
Security and Privacy: Managing the data must involve addressing the security and privacy needs in business. Expectation of managing the safeguarding of the database and infrastructure or hardware is done by cloud service providers. In case of remote areas, it becomes impossible to manage.
Vulnerability to Attack: In the opinions of Low et al. (2011), it is essential for the cloud computing firms to have proper assessment to the components. Connecting to the network does not ensure proper security and system. So, it suffers from the severe attacks and the breeches in security.
Limited control and flexibility: Users of cloud computing have limited control on operations and executing the infrastructure of host companies’. Certain limits can be imposed on the customers, who are engaged in the business for deployment by cloud provider like EULAs and management.
Platform Dependencies: As per the view Foster et al. (2008), platform dependency is also known as vendor lock-in system in case of cloud computing. Sometimes, it becomes impossible to move from one platform to another in case of differentiated deep-rooted vendor system.
Costs: In case of small and medium sized projects, cloud computing becomes costlier. Reducing staff level and hardware costs can be allowed through cloud computing, but it also results in raising the cost.
Conclusion:
On the basis of this report, it can be analyzed that the cloud computing is the most important part of the today’s business entities. The cloud computing is the cloud based software of computing systems as well as it is an online processing system. In this report, it can be analyzed that there are the five types of features of the cloud computing, which affect the computing systems. On the other hand, it can also be concluded that there are different kinds of benefits for Webb’s stores such as reduced costs, Flexibility, Increased storage. At the same time, it is also evaluated that there are different types of models of cloud computing systems like SAAS, IAAS, and PAAS.
