Cloud Computing Now and the Future Essay

The determination of vitiate calculate creates a growing interdependence among both public and private sector entities and the individuals served by these entities. This musical composition provides a snapshot of the advantages of fog computation and the risk areas specific to debauch advantage which clients of asperse services should be aware of. The coming(prenominal) of buy computing is certainly exciting, but moving more of our lives online mover we will inevitably be in possession of to consider the consequences. be confuse computing means dependence on others and that could designate our privacy because of policies to access our entropy, aegis could be a big issue and large companies like virago and Google could monopolize the market. The cloud is a metaphor for the space on the internet that after part store your teaching, as well as applications to manipulate data. It is not clear when the term cloud computing was first coined. For example, Bartholomew (200 9), Bogatin (2006) and some(prenominal) others suggested that cloud computing terminology was perhaps first coined by Google Chief Executive Eric Schmidt in 2006. Kaufman (2009 61) suggests that cloud computing terminology originates from the tele communions world of the 1990s, when providers began using virtual private network (VPN) services for data communication.There is however, agreement on the definition of cloud computing. The National Institute of Standards and Technology defines cloud computing as a model for enabling convenient, on-demand network access to a divided up pool of configurable computing resources (e.g. networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider fundamental interaction (Mell 2009 9). A information processing systems operating system, data and applications are typically installed and stored in the traditional computer purlieu. In a cloud computing envi ronment, individuals and product linees work with applications and data stored and/or maintained on shared machines in a web-based environment rather than somaticly located in the home of a exploiter or a corporate environment.Lew Tucker, Vice President and Chief Technology Officer of pervert reckoning at Sun Microsystems, explained that cloud computing is the movement of application services onto the internet and the increased use of the internet to access a wide variety of services traditionally originating from within a lodges data center (Creeger 2009 52). For example, web-based applications such as Googles Gmail can be accessed in authorized period from an Internet-connected machine anywhere in the world. Cloud computing provides an online environment that is scalable which facilitates the ability to hatch an increased volume of work without impacting on the performance of the system. The Cloud in any case offers significant computing capableness and economy of scale that might not otherwise be affordable to businesses, especially small and spiritualist size companies that whitethorn not have the financial and human resources to invest in IT infrastructure.Advantages include pileus costs and running costs. Companies can leverage the use of large scale resources from cloud service providers and summarize or remove capacity from their IT infrastructure to meet peak or fluctuating service demands eyepatch paying besides for the substantial capacity used (Sotomayor et. Al. 2009 14) on a pay-as-you-go economic model. It can also be significantly cheaper to rent added server space for a few hours at a time rather than maintain your own servers. Rental prices for Amazon E goic Compute Cloud (EC2), for example, are surrounded by US$0.020 and $2.970 per hour in Oregon as an example. Pay only for what you use. There is no stripped-down fee. On-Demand Instances let you pay for compute capacity by the hour with no long-term commitments.As you can se e in the above example the selected usage is 100 hours per month of On-Demand Instances, 10 reserved instances and molarity GB of storage for 50 IOPS and 100 Snapshot storages. The monthly cost for this company would be $1449.41 per month. This could be much more cost affective for a company than buying the hardware and storing the information themselves. The only question is, how unspoiled is this information that is being stored?The risk of cloud computing could be the security of the information being stored by a large company like Amazon. It is still unclear how safe out-sourced data is and when using these services ownership of data is not always clear. In a study do in 2009, a team of computer scientists from the University of California, San Diego and Massachusetts Institute of Technology examined the widely-used Amazon EC2 services. They found that it is practicable to map the internal cloud infrastructure, identify where a circumstance target VM is likely to reside, an d then instantiate new VMs until one is placed co-resident with the target (Ristenpart et al. 2009 199).This demonstrated that the research team was able to load their eavesdropping software onto the same servers hosting targeted websites (Hardesty 2009). By identifying the target VMs, attackers can potentially monitor the cache (a small allotment of fast memory used to store frequently-used information) in order to steal data hosted on the same physical machine (Hardesty 2009). Such an attack is also known as side-channel attack. The findings of this research may only be a proof-of-concept at this stage, but it raises concerns about the possibility of cloud computing servers being a primaeval point of vulnerability that can be viciously exploited.The cloud service providers establish the privacy policies to the companies that do business with them. The businesses are faced with their own privacy and confidentiality being determined by the terms of the cloud service providers. F ailure to comply with data protection legislation may lead to administrative, civil and criminal sanctions. Data confidentiality and privacy risks may be magnified when the cloud provider has reserved the right to interchange its terms at will (Gellman 2009 6).Some cloud service providers argue that such juridical issues may be capable of resolution contractually via SLAs (Service Level Agreements) and the like. Clients using cloud services could include clauses in their SLAs that indicate the law ranking the SLA, the choice of the competent court in case of disputes arising from the interpretation and the accomplishment of the contract. The Cloud Security Alliance (2009 28) also suggested that clients of cloud services should require their providers to deliver a door-to-door list of the regulations and statutes that govern the site and associated services and how compliance with these items is executed.Businesses should control that SLAs and other legally-binding contractual arrangements with cloud service providers comply with the applicable regulatory obligations (eg privacy laws) and industry standards, as the may be apt for breaching these regulations even when the data being breached is held or processed by the cloud service provider. Determining the law of the jurisdiction in which the SLA is held is an important issue. It may not, however, be as simple as examining the contractual laws that govern the operations of cloud service providers to determine which jurisdictions laws apply in any particular case. Gellman (2009 19) pointed out that the user may be unaware of the existence of a second-degree provider or the actual location of the users dataand it may be impossible for a casual user to know in advance or with certainty which jurisdictions law actually applies to information entrusted to a cloud provider.Businesses should continue to conduct payable diligence on cloud service providers, have a comprehensive compliance framework and ensure that protocols are in place to ceaselessly monitor and manage cloud service providers, offshore vendors and their associated outsourcing relationships. This would ensure businesses have a detailed brain of the data storage information to maintain some degree of oversight and ensure that an acceptable earmark and access mechanism is in place to meet their privacy and confidentiality needs. This would also ensure a high consumer confidence level in the entire cloud computing industry. The future looks bright for cloud computing. subsist summer Google made a very large investment in bringing Google Fiber to Kansas City, wideband internet that is 100 times faster than what we currently have today. Faster internet speeds means bigger files can be stored and downloaded from the cloud.Netflix says, Its the most consistently fast ISP in America. Analysts from BTIG Research visited Kansas City last month and were blown away, by the service (Jeff Saginor 2012 1). But at its heart, Googl es attempt at being its own ISP is much more about forcing the entrenched service providers the Verizons and Time Warners and AT&Ts of this world to step up their games than it is about making this particular business a raving financial success. Saginor goes on to say, When I asked the Google spokeswoman what the ultimate goal of all this was, she replied that Google wants to fix the web better and faster for all users. The implication is that they dont want to just do it all themselves. Cloud computing means dependence on others and that could limit our privacy because of policies to access our information, security could be a big issue and large companies like Amazon and Google could monopolize the market.The Cloud provides an online environment that is scalable which facilitates the ability to handle an increased volume of work without impacting on the performance of the system. The risk of the cloud could be the security of the information being stored by a large company. It i s still unclear how safe out-sourced data is and when using these services ownership of data is not always clear. Businesses should continue to conduct due diligence on cloud service providers, have a comprehensive compliance framework and ensure that protocols are in place to continuously monitor and manage cloud service providers, offshore vendors and their associated outsourcing relationships. The future of cloud computing is certainly exciting, but moving more of our lives online means we will inevitably have to consider privacy, security and ownership of the information.ReferencesAmazon Web Services http//aws.amazon.com/ec2/pricing/Creeger M 2009.
