Understanding Cloud Computing: Advantages, Disadvantages & Security Issues Essay.

The focus is also on providing a scalable infrastructure for the application, data and the file storage where the advent of this technology is based on the cost of computation, application hosting and handling the storage of the content through a proper delivery of the data as well (Harris, 2013 pp.

Bad Effects on Employees

The cloud computing has been promising for the ease of use and cost-effectiveness. It has been able to focus on the realities and the risks of the model, components and the characteristics. The focus is also on providing a scalable infrastructure for the application, data and the file storage where the advent of this technology is based on the cost of computation, application hosting and handling the storage of the content through a proper delivery of the data as well (Harris, 2013 pp. 1-2). Cloud computing has made it easy to handle the different types of direct cost benefits with the potential to transform the data from a capital intensive to a variable priced environment. The idea is mainly about the reusability of IT capabilities and handle the software data centres through the self-service management and pay-per-use feature. One needs to understand the enterprise which choose to deploy the applications on the public, private and the hybrid clouds, where the cloud integrators tend to play a major role in handling the superior economies of scale to customers. The model aims to address on data security and greater control that lacks in a public cloud.

Cloud computing has a major disadvantage when it comes to handling the economic standards. It has been seen that there is a major move from the capital expenditure to the operating procedures, where the considerable implications are related to accounting and other investment practices (Rangendran, 2013). The shifting in the work will have a major effect on the labour market with displacement of the employees and their skills.

The major impact can be the failure of communication, the deterioration of the quality of service with ceasing all the operations (Devasena, 2014). The employees will be handling the sending of data with the tapping of communication line and corrupting the data or stealing it from the disk storage.  

The impact of cloud computing on employees also include the scalability to store and handle the large amount of data. It has been critical and there is no proper availability of the data. One of the pressing demands is to serve the needs of the mobile user in a short time. There is a major security breach and issues when related to the addressing and delivering the high-quality services of data (Hashem et al., 2015). Along with this, the major impact is on the data processing where the employees have to handle the growth of data from multiple sources and then take hold of semi-structured data formats only to a certain extent.

The major issue is also related to the software and the hardware architecture, where problems are related to the reliability and the barriers of pricing, capacity and the lack of query processing techniques (Diakaiokos et al., 2009). There is a need to handle the input output operations per second to work with a greater capacity at a faster pace. The issues of how the hackers can use the virtualised infrastructure is also a major problem for the people.

Security

The security is an issue for the cloud provider and the client. For IaaS model, the physical security, environment and the virtualisation software security need to be acknowledged with proper applications and data (Ogigau, 2012 pp., 144-145). The issue also arises with the security and confidentiality where one can access or modify the data, check what happens to the data when it is deleted, or about the security lifecycle.

The security issues involve the identification of selected security controls with major effect on handling the reliability, maintainability and supportability (Zissis et al., 2012).  The software confidentiality is considered important and needs to be handled to maintain the integrity of information and preventing the loss or modification due to any unauthorised access or component failure.

There is a need to take hold of how management of hosting companies or colocation services are set. With this, the cloud also has to focus on compelling value proposition in terms of cost, perimeter wall and load balancing (Subhashini et al., 2011). The focus is on portability of application, with issues related to web application security and data breach.

The traditional risks were mainly about the confidentiality, integrity and the availability of the system (Asma et al., 2012). There are other issues related to the management of entity admittances and the rights to specific enterprise resources that ensure the valuable data and services, misappropriated or stolen.

The cloud computing is mainly to handle the sharing of configurable resources which includes the network, servers, storage and the applications (Mell et al., 2011). They are mainly for handling the three service models with the broad network access and rapid elasticity that could handle the capability to match the monitoring and control for the provider and the consumer of utilised service.

The storage includes the data integrity verification for the different untrusted servers. The experience of the failure is mainly to decide and hide any data errors from the client for the benefit of the company (Wang et al., 2011). The major issue is about the verification and high scheme efficiency, stateless standards and public verifiability to challenge the correctness of the data storage.  

The cloud storage is mainly to handle the data and work on the high-quality cloud applications without any burden of the local hardware and the software management. Here, the distributed storage integrity auditing mechanism is set to utilise the distributed coded data. Along with this, the internet based online services also provide a huge amount of computing resources with local machines set for data maintenance (Wang et al., 2012). The supporting dynamic data operations are based on working with limited attention in data possession applications.

The capability is mainly based on deploying the cloud consumer created with applications through using different programming languages (Zhang et al., 2010). In order to work with the proper on-demand data correctness, there is a need to be updated by the users through insertion, deletion, modification and appending.

The cloud computing is able to handle the data effectively and in a much faster process, where the manual process could be mainly for cloud computing that is not integrate into digital forensics (Martini et al., 2013). This will be a very time-consuming process along with which it will be difficult to decrypt the files manually which will be an effort.

Storage

The manual calculation of the solution will lead to higher estimated costs and less accuracy. The cloud computing helps in handling the cloud storage services with proper estimation of cost savings, using Azure and local clouds under different data requirements (Ruiz et al., 2011). Here, cloud computing will help in easily storing the different range of devices and handle the different understanding of artefacts which focus on client and server.

The manual storage is lessened, and cloud computing need to focus on self-services with resource flexibility and pricing is determined on the level of usage (Govinda et al., 2012). The cloud allows a proper investigations and auditing of outsourcing the data to ensure the data security as well.

The cloud computing has been helpful in handling the elimination of up-front by cloud users and allowing the companies to start with the increased hardware resources (Armbrust et al., 2010). The ability to pay for the use of computing resources with the short-term basis helps in handling the automatic scalability and failover mainly because of the semantics because they are set with the state management issues that are highly application dependent.

Conclusion:

The cloud computing has been able to work on the business strategy formulation and accomplishment of the near future. The SMEs are working over improved security and privacy so that there is an effective cost reduction and finding easy use, convenient and secured business forms. The cloud computing focus on the cloud consolidation and aggregation of resources where a proper support for change in business model is important for the IT governance arrangement. The outsourcing is set with the upskills of the employees which is based on the IT shared services, virtualisation and using the multiple technology platforms (Devasena, 2014 pp.,5-6). The backup and storage are important for collaboration which indicates that there is a preference of face-to-face meetings, possessing physical devices and working on sharing and collaboration. Along with this, the cloud computing helps in handling the security and privacy to monitor the activities and tracking the transactions, providing a selective access to the users and utilising a strong password. The reliability is also important with built-in factors so that one can easily match to the downtime of various commercial cloud solutions like Amazon, Gmail and Google Docs.
