Cloud Computing †Risk or Opportunity Essay

Abstract streak figuring is a marge that refers to sources and ready reckoner systems useable on demand through the engagement, which evict set up a number of computer run integrated without being restricted local resources in rank to discombobulate it easier for the enforcer and include those resources space for information backup and synchronization self besides includes processing capabilities softw atomic number 18 and computer programing of tasks and push e-mail and remote printing, and the substance abuser can control when it is affiliated to the interlock in these resources through a simple softw atomic number 18 user interface simplifies and ignores a lot of detail and internal processes. misdirect reason has bring to pass increasingly popular because it supplys users the illusion of having infinite calculation resources, of which they can use as much as they need, without having to worry near how those resources atomic number 18 provided. It with al provides greater scalability, availability, and reliability than users could achieve with their own resource The core topographic point in corrupt compute that held work out in the befog for clarity, the word process (and cogitate data) is not confined to the place (places) privy and unknown. Thus, this precedent is the antithesis of the treatment process is located in one or much of the servers are healthy known. Exposure vex hide of criticism and pom-pom because of privacy advocates, for the ease of prominent governing the hosting companies for run over debase, and then, can cut back censorship and domination, whether legal or illegal, the communication process as well as the data stored in between the user and the host familyIntroduction mist deliberation has become a ubiquitous term and largely discussed topic in the global information technology (IT) world. befoul computing has changed dramatically the ways in which organizations and individuals commu nicate, collaborate and compute. The idea of be subvert computing ensures a cost stiff changeation of utility computing principle that allows users and providers a convenient find to resources in a self- at tip and present as you go fashion. Consequently, profane computing has reduce the cost associated with system administration as well as aided in improving resource utilization and accounting. Since last few years, subvert computing has rooted in a number of positive impacts on the IT ecosystem, thereby giving rise to new securities industrys and widely scattered new user communities (European Commission, 2012).Contextually, the concept of befoul computing is the outcome of the direct industrial require to enhance resource utilization without intervening consumer requirements. In other words, the concept ensures the use of the available resources in more than efficient manner (European Commission, 2012). The composition intends to critically examine the opportunitie s and the in trade protections associated with demoralize computing and draws a valid proof on its adoption by organizations. mottle reckon Definition, Models and Services sully computing was initially used in an academic perspective by Prof. Kenneth K Chellapa who illustrated it in 1997 at the Informs Conference in Dallas as a computing paradigm where the boundaries of computing impart be determined by economic rationale rather than technical limits (Petri, 2010). There are miscellaneous definitions of mottle computing however the most appropriate and broadly legitimate definition is being provided by North America National fetch for Standards and Technology (NIST). fit in to NIST, becloud computer science is a put for enable convenient, on demand network access to a shared pussycat of configurable computing resources that can be rapidly provisioned and released with minimal attention elbow grease to serve well provider interaction (Petri, 2010). There are numero us defame computing models for trading purposes including Public Cloud Public profane model is provided by vendors and can be accessed over the internet or common soldier network. One or more data centers are used by this model which is shared by fourfold customers (Weitz, 2010). closed-door Cloud Private blot out model is managed and used internally by the organizations which utilizes shared receipts model and makes variable usage of virtualized computing resources. The data stored in the model are managed within the organization (Weitz, 2010). Hybrid Cloud As the bear on suggests, the hybrid model is the mixture of existence mist services and private misdirect architecture. The model is designed to meet accredited specific needs of customers (Weitz, 2010). Community Cloud Community grease ones palms model is used crossways the organizations having similar requirements and objectives. Community blotch model is established using public cloud services in order to ensu re collaboration among the companies (Weitz, 2010). Cloud Computing ServicesCloud computing services are provided mostly in the following ways Software-as-a-Service (SaaS) Software-as-a-Service (SaaS) has been operational in the market since m whatever years. Currently, vexationes are more interested in shifting licensing software to stand services particularly on the basis of per user and per month among others (Weitz, 2010). Platform-as-a-Service (PaaS) Platform-as-a-Service (PaaS) includes outgrowth of such environment that allows developers to build software applications that can be offered as services to customers or to general users (Weitz, 2010). Infrastructure-as-a-Service (IaaS) Infrastructure-as-a-Service (IaaS) provides customers or users with storage, network and other respective(a) fundamental resource requirements in order to run arbitrary applications (Weitz, 2010).lit Review fit in to Etro (2009), cloud computing is a newly evolved internet based technology t hat stores large information in servers and provides that information as services on demand to clients. Accordingly, its impact is spectacular on some(prenominal) consumers and companies.Furthermore, he tell that consumers can access all their documents and data from any devices such as laptops, mobile phones and tablets while the companies can rent ironware and software from the service providers and pay as they use the services care other services availed by the companies such as electricity (Etro, 2009). Petri (2010) postulates that, cloud computing is one of the most discussed IT innovations in the last few years. Hence, risk management is the most critical area which draws a serious attention. He emphasized that future is relatively un authorized when associating cloud computing with security department factor. He critically points out that cloud vendors should quickly address the security and other relate to concerns for ensuring better customer satisfaction (Petri, 2 010). According to Bein, Bein & Madiraju (2010), cloud computing is a new paradigm of computing that has evolved in the recent times as an expensive way for providing storage and software.They further accented that many companies are moving ahead with an intention to make cloud computing easy to use. They advocated that there are huge potential for consumers to achievement the cloud computing technology (Bein, Bein & Madiraju, 2010). According to Gartner Inc (2012), continuous monitoring of cloud computing technologies and usual updates to the enterprisingnesss cloud strategies are necessary to pr resolution any cost related errors for the subsequent few years. It also say that cloud computing technology will use up significant impact on the level of its adoption over a period of time (Gartner Inc, 2012) According to Pokhriyal (2012), cloud computing would contribute towards increasing complexities relating to data storage and users access to applications as well as other frequ ently conducted processes. She also stated that risk of exposure of critical data is more with the use of cloud computing technology.She advocated that business firms whitethorn also witness security breaches and hacking that shall make the cloud storage relatively ineffective and inefficient (Pokhriyal, 2012). According to Willcocks, Venters, & whitey (2011), cloud computing technology is changing the ways of IT business services in terms of data delivering and managing. Accordingly, cloud computing has escalated the importance of delivering effective services and for this reason the IT and business services urgently need to ascent the level of service competency and should focus on the availability of grapheme services to meet the customer expectations (Willocks, Venters, & Whitley, 2011). In the words of Horwath, Chan, Leung, & Pili (2012), cloud computing has the potential to bring plastered drastic changes in the organizations as witnessed in case of the internet during the last decade of the 20th century.They emphasized that by applying cloud computing technology without proper care and payable-diligence whitethorn result in unforeseen problems. Consequently, executives must be aware of risks and other issues of cloud computing in order to derive significant benefits out of the provided services (Horwath, Chan, Leung, & Pili, 2012). According to Santos, Gummadi, & Rodrigues (2012), cloud computing enables organizations to cut be associated with resource storage, network bandwidth and other pertinent data. However, they argued that concerns about the privacy, confidentiality and integrity of the data and computation can be considered to be the major deterrents for those organizations which are looking forward to encompass cloud computing (Santos, Gummadi, & Rodrigues, 2012). According to Hinchcliffe (2009), cloud computing will transform IT business scenario by a large extent and it will reach to equaliser between therisks and the benefits associ ated with cloud computing models.Therefore, he points out authentic major risks associated with such transformations including security of organizational data that is stored in the cloud, divergence of control over cloud resources and reliability factor. He also stated that the efficient use of cloud computing will enable market validation and prototyping of new approaches at much faster and relatively less(prenominal) expensive rate than ever before (Hinchcliffe, 2009). According to Weitz (2010), cloud computing will be playing a major role in the future of IT and shall bring in enormous opportunities for the organizations. Consequently, he stated that larger organizations will also have an opportunity for cutting the existing costs of IT al-Qaeda with the use of cloud computing models.However, he also highlighted the risks related with cloud computing and expressed his deep concerns relating to the security and confidentiality of certain relevant data (Weitz, 2010). Hyek (2011 ) in his report, Cloud Computing Issues and Impacts, postulated that, cloud computing models should honor with laws and regulations in each of its operations. The processing of data by the cloud service providers must be in conformity with governments requirements (Hyek, 2011). According to Curtis, Heckman, & Thorp (2010), the most primal factor related with the cloud computing model is the concern about the security and privacy of data while adopting cloud computing models (Curtis, Heckman, & Thorp, 2010).According to the Australian Academy of expert Sciences and Engineering (2010), in its report, Cloud Computing Opportunities and Challenges for Australia considers the importance of government and its roles in encouraging researchers and business sectors to adopt cloud computing models. The report emphasized that government should formulate strategies that initiate business sectors to adopt cloud models for their resource and application requirements. The report precisely expos it the responsibility of the cloud service providers in terms of proper management of data in order to prevent any situation that may result in loss of vital data (Australian Academy of Technological Sciences and Engineering, 2010).According to Catteddu & Hogben, (2009) cloud services provide expedient storage convenient by various devices along with other benefits including useful communication and flash multi-point collaboration. They also emphasized that level of risk may tend to veer significantly based on the type of cloud model. It is for this reason that customers should be aware of the probable risks associated with cloud computing models and they should strive to transfer the risks to the providers (Catteddu & Hogben, 2009).Characteristics of Cloud ComputingA few of the relevant characteristics of cloud computing are elaborated below On-Demand Self Service Cloud computing providers offer various computer services such as applications, e-mail and network without involvin g human interaction with various service providers engaged in certain specific services only. Currently, there are three-fold organizations that provide cloud computing services based on on-demand self services such as Google, Amazon Web, Microsoft and IBM among others (Information System study and take Association, Inc, 2012). Broad net profit Access Cloud services are available over the network, specifically over the internet and are accessed through certain standard mechanisms such as personal laptops, mobile phones, tablets and iPads among others (Information System Audit and Control Association, Inc, 2012). imagination Pooling The cloud computing models of the providers are shared with various resources in order to serve multiple clients. The resources united together may consist of processing, network bandwidth, storage of data, memory, virtual machines and email service (Information System Audit and Control Association, Inc, 2012).Rapid ElasticityThe capacities of cloud s ervices can be fleetly and elastically provisioned, in a few instances robotically as well to quickly balance out and release to scale in quickly. Furthermore, the capacities accessible for provisioning frequently come forth to be infinite and can be procured in any standard at any time (Information System Audit and Control Association, Inc, 2012). metric Services The resource usage of cloud computing can be measured and reported to both providers and customers related to the amount of services use. Hence, cloud computing service providers charge the customers for the resources that they have actually used i.e. pay as you use. Considering the fact, more the customers utilize the cloud computing services, more they have to pay and vice-versa (Information System Audit and Control Association, Inc, 2012). Multi-tenacity Multi-tenacity is one come upon characteristics related to cloud computing which is being advocated by Security Alliance. Multi-tenacity is related with the requi rement for segmentation, policy-driven enforcement, control, service levels, billing models and isolation for the different consumer requirements (Information System Audit and Control Association, Inc, 2012).Cloud Computing Opportunities and Risk Assessment Cloud Computing Opportunities Opportunities derived from cloud computing are related with cost reduction to emergence flexibility and decrease complexity which benefits the customers in terms of higher returns on their investments. Certain vital opportunities and benefits provided by cloud computing comprise damage Saving Cloud computing customers are liable to pay merely for computing services and resources that they use rather than making permanent investments on resources or leasing equipments that may or may not be utilized fully at all times. Cloud computing enables to share IT resources with multiple organizations and facilitates them to access as per their requirements which can be related as in operation(p) expenses ( OPEX) and not as capital expenses (CAPEX) (Petri, 2010). Speed of Deployment Cloud service providers can meet the needs of the organizations for computing resources quickly and efficiently than other internal information technology functions. The customers do not have to wait for months for crunching large data.They can simply rent resources for limited period and can avail huge benefits at considerably reduced time (Petri, 2010). Scalability and Better coincidence of Technology Resources An organization is able to scale up as well as down its capability from a single server to multiple numbers of servers with no capital expenses through the use of cloud service models. An organization is also able to deploy additional storage efficiency over the web (Petri, 2010). Decreased Efforts in Managing Technology Owning and operating of IT functions are often costly and time consuming. However, cloud computing enables an organization to tolerate more time on its purposes and goals (Petri , 2010). Environmental Benefits Cloud computing also results in environmental benefits. If all the organizations replace their private data centers with cloud computing, it will significantly reduce the overall power consumption and coulomb emissions (Petri, 2010). Higher entertain Added Cloud computing does not only provide software functionality but it also provides the customers with relevant information and data which was traditionallysupposed to be created by the customers themselves (Petri, 2010).Cloud Computing RisksRisk is an event that prevents the organizations from achieving their determined purposes and objectives. Certain risks associated with cloud computing are stated below Disruptive Force Facilitating innovation and cost saving aspects can itself be viewed as risk to the existing cloud computing organizations. By lowering the barriers to entry, new competitors may pose a serious threat to certain cloud computing business models (Horwath, Chan, Leung, & Pili, 2012 ). Residing In the Same Risk Ecosystem as the Cloud Service Provider (CSP) and Other Tenants of the Cloud Organizational conviction on third party involved in managing cloud solutions will increase legal responsibility and incident escalation among other core areas. By following the actions of CSP may impact the organizations in certain direct and indirect ways (Horwath, Chan, Leung, & Pili, 2012). Lack of Transparency A cloud computing service provider does not facilitate complete information regarding its processes and operations.Consequently, cloud customers have only little knowledge about the storage locations and algorithms that are implemented or used by the cloud service providers in telling to computing and controlling resources of customers data (Horwath, Chan, Leung, & Pili, 2012). Reliability and Performance Issues Even though efficiency of cloud computing may get disrupted due to risk events such as system failure that may pass along without any early alerts to the end users. Hence, system failure may be viewed as a distinctive challenge posed to cloud computing (Horwath, Chan, Leung, & Pili, 2012). Security And Compliance Concerns Cloud computing supports various processes that may tend to evolve security and retention concerns in relation to its compliance with certain specific laws such as Health Insurance Portability and Accountability function of 1996 (HIPAA).The cloud service providers may have no obligation to break out such information associated with privacy of certain laws such as US Patriot Act and EU Data Protection Directives among others (Horwath, Chan, Leung, & Pili, 2012). High Value Cyber Attack Targets The over-dependence of multiple organizations on single cloud service providers may tend to create picture of cyber attacks then those used by a single organization (Horwath, Chan, Leung, & Pili, 2012). Risk of Data Leakage The risk of data leakage is also more where multiple organizations share their resources through cloud environment. Consequently, cloud service providers do not provide adequate data privacy and confidentiality of resources which the organizations intend to secure from intruders (Horwath, Chan, Leung, & Pili, 2012).ConclusionCloud computing has changed dramatically the ways in which the organizations communicate, collaborate and compute. In general, cloud computing refers to words of scalable IT resources over the web particularly internet. An organization can purchase or rent software on need basis or according to usage which results in less investment and consumption on the part of the organization. Cloud computing facilitates the organizations to manage their IT requirements remotely, at much bring down costs. It further enables organizations to share resources in a single place or through a single cloud service provider. The organizations do not have to make heavy investments on establishment of their own IT infrastructure as cloud computing models provide organizations with established database for fulfillment of their IT demand. Moreover, organizations and users are charged or billed on the basis of their resource consumption. condescension having numerous benefits of adopting cloud computing models, there also exist certain risk factors which restrict the scope of cloud computing. Security and privacy are the prime issues restricting the adoption of cloud computing. Since multiple organizations will be consolidated on single cloud computing, there exists more vulnerability of data hacking. Consequently, cloud computing service providers do not control the adequate safety for data losses and leakages which at times deters organizations from adopting cloud computing solutions. Nonetheless, if organizations cautiously consider the risk factors associated with cloud computing related solutions then these risk events can be overcome efficiently. Considering this aspect, it can be stated that organizations should adopt cloud computing solutions. By adopti ng cloud computing solutions, they can avail numerous opportunities that shall help them to grow and sustain their business profitably.
