Cloud Computing and Virtualisation
Cloud Computing Technology
Cloud Computing Technology
Cloud system is a modern technological development in the ICT sector, which provides organizations with increased capacity of handling data (Fehling et al., 2012). S-Mart is a company that intends to adopt the cloud technology as a solution for its large customer base. The organization manages to stock over 50,000 products in established supermarkets like the Woolworth, Coles, Aldi, and IGA. The nature of the workload that the organization has to deal with is so large and overwhelming for its current resources. This article will discuss the benefits and the risks in cloud technology that S-Mart is likely to face if cloud technology is adopted. The paper will also discuss the model that will suit the organizations.
Five benefits of cloud system
S-Mart stands to benefit in some ways if the top management decides to adopt the cloud system in its ICT department (Merrill, 2014). The first benefit is the reduced cost of infrastructure because the power for computing is provided infractions. The fraction implies that the cost of computing power is shared between the service provider and S-Mart. Very few companies have had the capacity to afford their computing capacity due to its capital-intensive nature. The overhead cost of management can be greatly reduced to help S-Mart reduce the total cost of operation. Another area where cost is saved is the maintenance of the computer infrastructure (Kamal, 2015). When cloud computing is adopted, the cost of maintenance of infrastructure is transferred to the service provider. The second benefit that the company stands to benefit includes capacity, scalability, and speed (Bahga and Madisetti, 2013). With cloud computing, S-Mart will no longer be required to acquire computer devices with increased capacity of storage. Cloud technology has been cited as scalable a feature the organization can benefit. The speed of sending and accessing data is greatly increased when cloud computing is used.
The third benefit is that is that S-Mart will have an opportunity to enhance its security and backup (Kamal, 2015). One feature of public cloud computing is that the data security is the main backbone and is combined with geography-based redundancies for increased availability. Cloud providers have the available resources to invest in both data and physical security (Merrill, 2014). Another benefit is that the S-Mart will improve the availability of data, geography and mobility convenience. With the increased use of the internet around the globe, the adoption of the cloud-based technology would also increase the access of data. The inconveniences of geography and mobility are also reduced. The fifth and last benefit for the S-Mart company is that it would easily comply with the regulatory requirements as far as organizational data management is concerned.
Five risks of cloud system
Despite the fact that cloud computing may have several advantages, there are five risks associated with the information system technology (Merrill, 2014). The first risk is like the contracts provided by the hosts regarding
biases. This risk requires a company to maintain a close relationship with legal departments to ensure that the nature of the contract is not fake. One of the terms to consider when negotiating terms and conditions with cloud providers are friendly terms which providers may often fail to guarantee. Unfavorable terms and conditions by the cloud providers may result to risk on the users and specifically the consumers or customers.
According to Fehling et al. (2014), another second risk of cloud, computing is a loss of control of data by the client. S-Mart stands a risk of losing control of its data despite the fact that the company wants to use the technology to control data around the world. In case a
particular set of data has been compromised, the company may find it hard to establish the exactly compromised data set. The third risk that S-Mart is likely to face is the aggregation risk (Merrill, 2014). It is clear that the aggregate wealth of the S-Mart organization is very large but this does not match to the total number of vendors sharing the same cloud. There is still a risk of aggregation of data if the organization plans to use the cloud system.
The fourth risk of the cloud computing S-Mart is likely to face is the cost of the technology (Kamal, 2015). Cloud computing has several attached costs such as transfer costs and regulatory compliance costs. The cost of service does not include the cost incurred when a risk surfaces and this keeps the service provider on a profitable ground at all the time. Lastly, S-mart is likely to face some data security concerns since the cloud may have many users. The risk is likely to be magnified in a situation where S-mart over-relies on one service provider to take care of all the data. S-Mart must consider the fact that the regulation holds the vendor responsible for any misaligned data and not the service provider.
Cloud-based system design and justification
A pattern for cloud offering would be used to explain how the cloud-based technology can be used to enable storage, accessing, updating, processing and, securing sharing and publication of data.
According to Fehling et al. (2014), the cloud environment is made up of two components, which are the elastic infrastructure and the elastic platform and can either be in the form of IaaS or PaaS cloud. Two approaches are recognized in this area, which is the node-based availability, and the environment based availability. The two approaches assure the availability of S-Mart resources and availability of the services offered. The cloud offerings that combine to create either IaaS or PaaS are of three types, processing, storage and communication offering. The function of the processing offering is to execute the S-Mart workload, which may be, executed the service provider or S-Mart using custom software. Application server platforms are hosted
in this area of the cloud system.
The storage offering has a primary function of storing S-Mart’s data in the cloud system and relies on the service model (Bahga and Madisetti, 2013). The region allows the use hard drive storage resources on the IaaS and may enable network storage capabilities on the PaaS. In the PaaS, the data may be provided as shared folders, table centric and relational models. The communication offering is essential in the exchange of information among the various applications in the cloud system. The
exchange of information may also involve the application that is not cloud-base.
The storage offering can be categorized in both the elastic infrastructure and the elastic platform. The storage system can allow S-Mart to ensure block storage for large amounts of data. The
elastic storage has the capability to handle a data type known as the binary large object (BLOB). The cloud computing offerings have several advantages that have been discussed before.
According to Mahmood and Saeed (2013), the model will be useful to A-Mart since there is an elastic load balancer that allows automatic determination of the amount of request and allocation of resources. The automation process responds to the requests and the fluctuations in the number of requests, which will be beneficial to S-Mart large market base. The behavior can also be enhanced to be real-time, and this can enhance communication. The model provides an opportunity asynchronous requests where an additional layer meant for optimization can be included. The design allows processing of non-business data or that which I s not time critical to be processed later. The shift allows extra space for processing of real-time data. Elastic can be handy in the distribution of several requests for processing by the various cloud application. The implementation of the model can be achieved using the following procedure as recommended by (Fehling et al., 2012).
Cloud-based technology is a modern development if the communication and information sector which has many benefits for an organization. The technology allows an organization to handle huge amounts of data and even offer real-time responses to several requests. S-Mart has large amounts of data, which can benefit from the technology. The model has been provided to help S-Mart deal with data across its large customer base.
