Cloud computing not feasible – security hurdles

Virtualization brings new risks mainly in the virtual machine being abused, the virtual machine escape, and multi-tenant isolation between the failures of security policy migration of virtual machines.

Shared Data Security Environment

Under the cloud service model, users are very worried about whether the data stored in the service provider will be compromised, tampered, or lost. Man-made threats facing the user data mainly come from service providers, hackers, malicious neighboring tenants, and subsequent tenants.

Cloud Platform Application Security

There are some application security problems existing in Cloud Computing Services, no matter Saas, Paas or Iaas, mainly including three categories. The first one is the malicious program review. The second one is the application interface security. The third one is code and test safety.

Authentication and Access Control in the Cloud Service Model

Under the cloud service model, user authentication and access control face new challenges, for example, the authentication and authorization of massive users, the rational division of access rights, and the management of accounts, passwords, and keys. In dealing with massive users’ changeable business and their identification, the cloud service providers need to fully automate users’ authentication and access management.

Turn: Warming

The cloud uniquely makes warming worse

Matthews 2013 (Richard; How environmentally sustainable is cloud computing and storage?; Sep 12; globalwarmingisreal.com/2013/09/12/sustainable-cloud-computing/; kdf)

Critique The cloud industry has also been called secretive, slow to change its practices, and overly optimistic in its environmental assessments. The massive energy requirement of cloud computing can create environmental problems. According to a 2012 report in the New York Times, data centers use 30 billion watts of electricity per year globally and the U.S. is responsible for one-third of that amount (10 billion watts). A Gartner report indicated that the IT industry is responsible for as much greenhouse gas generation as the aviation industry (2 percent of the world’s carbon emissions). Just one of these massive server farms can consume the energy equivalent of 180 000 homes. According to a McKinsey & Company report commissioned by the Times, between 6 and 12 percent of that energy powers actual computations; the rest keeps servers running in case of a surge or crash. “This is an industry dirty secret,” an anonymous executive told the Times. However, cloud supporters counter that this may be better understood as a necessary evil if data companies are to ensure that they are able to provide reliable service at all times. Greenpeace has published a report, “A Clean Energy Road Map for Apple,” that follows up on the organization’s April “How Clean is Your Cloud?” report. These studies indicate that many cloud providers use energy sources that are neither clean nor sustainable. The Greenpeace analysis showed that tech companies like Akamai and Yahoo! are the most environment-friendly while companies like Amazon, Apple and Microsoft each rely heavily on power from fossil fuels. Cloud computing is almost directly responsible for the carbon intensity increase at Apple, which gets 60 percent of its power from coal. Although Apple is increasing the amount of renewable energy used to power its cloud computing, the company has been criticized by Greenpeace for moving slowly. In May 2013, Apple said that its North Carolina data center will be exclusively reliant on renewable power by year’s end, and that all three of its major data centers will be coal-free by the end of this year. Solutions Despite all of this convincing data, it is important to understand that saving energy does not always mean that you are reducing your GHG emissions. To be environmentally sustainable these centers must draw their power from renewable sources of energy. The location of cloud servers is the key issue that determines whether this is a truly sustainable option. Ideally, cloud computing centers should be located in places where the grid portfolio is clean. (It would be even better if these data centers generated power themselves from renewable sources.)

Climate Change is a threat magnifier—policy making must focus on finding the best avenue to avert disaster

Pascual and Elkind 2010 (Carlos [US Ambassador to Mexico, Served as VP of foreign policy @ Brookings]; Jonathan [principal dep ass sec for policy and int energy @ DOE]; Energy Security; p 5; kdf)

Climate change is arguably the greatest challenge facing the human race.¶ It poses profound risks to the natural systems that sustain life on Earth and¶ consequently creates great challenges for human lives, national economies,¶ nations' security, and international governance. New scientific reports¶ emerging from one year to the next detail ever more alarming potential¶ impacts and risks.¶ It is increasingly common for analysts and policymakers to refer to¶ climate change as a threat multiplier, a destructive force that will exacerbate¶ existing social, environmental, economic, and humanitarian stresses.¶ The warming climate is predicted to bring about prolonged droughts¶ in already dry regions, flooding along coasts and even inland rivers, an¶ overall increase in severe weather events, rising seas, and the spread of¶ disease, to cite just a few examples. Such impacts may spark conflict in¶ weak states, lead to the displacement of millions of people, create environmental¶ refugees, and intensify competition over increasingly scarce¶ resources.¶ One of the great challenges of climate change is, indeed, the scope of¶ the phenomenon. The ongoing warming of the globe results chiefly from¶ one of the most ubiquitous of human practices, the conversion of fossil fuels¶ into energy through simple combustion. Halting and reversing climate¶ change, however, will require both unproven-perhaps even unimaginedtechnology¶ and sustained political commitment. We must change living¶ habits in all corners of the globe over the course of the next several decades.¶ We must resist the impulse to leave the problem for those who follow us¶ or to relax our efforts if we achieve a few years of promising progress. The¶ profound challenge will lie in the need for successive rounds of sustained¶ policymaking, successive waves of technological innovation, and ongoing¶ evolution of the ways in which we live our lives.

Cloud Computing – Bad

Cloud computing capabilities are all hype

Marks 13 - Publisher of six best-selling books on small business management (Gene, 10/21/13, "The Embarrassing Truth about the hybrid cloud" www.forbes.com/sites/quickerbettertech/2013/10/21/the-embarrassing-truth-about-the-hybrid-cloud/)

Why the growth in hybrid cloud technology? Well, that’s the embarrassing secret no one wants to admit. Some may say it’s validation of the cloud’s role in a company’s infrastructure. I’m not so sure. In my opinion, it actually represents the limitations of the cloud. The cloud has received a lot of hype over the past few years. But now smarter people are starting to better understand its reality. “IT departments are starting to rationalize the cloud as just part of an infrastructure,” says Mike Maples, managing partner at Palo Alto-based FLOODGATE Fund. “You can’t just let all the bits of your enterprise go to the cloud. It’s not all or nothing. The world is becoming a more hybrid enterprise.” Cloud based applications have exploded over the past few years. Collaboration services, mobile apps, customer relationship management systems and document storage offerings have literally changed the lives of consumers and employees at companies, big and small. I am accessing my customers’ data from a smartphone on a plane at 30,000 feet. A roofer is creating a work-order for a new job while holding onto a chimney and entering the data into his tablet. A college kid sits on a train from New York to Boston and catches up on the latest episodes of Walking Dead on her iPad. It’s glorious. It’s mind-blogging. And it’s maddening too. Because with all the hype, with all the excitement, with all the money thrown at it, the cloud has been disappointingly and embarrassingly imperfect. Yes, I am accessing my customers’ data from 30,000 feet but the connection is so slow and drops so many times that it takes me ten times as long to retrieve the information I’m looking for. The customer’s credit card information that the roofer is entering into his tablet is being snagged by the guy three streets over who has hacked into his connection. That college kid audibly groans as the episode freezes and her screen goes black, time and time again, eventually pulling out a book. The cloud will be wondrous and fast and secure and reliable…one day. Today, it is not. And until that day comes we have the hybrid cloud. Why else would Carbonite, whose model has been built around delivering a cloud based backup service, release an on-premise storage device to complement their online service? Why would VMWare and Microsoft MSFT -0.2% duplicate data delivery to multiple servers? Why would venture capital firms plough millions into a software base service like Egnyte so that users can get the same data that is stored in different locations? It’s because the cloud is useless unless we can get to our data fast. The cloud is useless if it’s not making us more productive and enabling us to do things quicker than before. It’s useless if our data is less secure than when it was stored on our own servers. And without hybrid cloud technologies, many companies are learning that this is very much the case. So over the course of technology history our data has travelled from server to desktop to cloud and now back to the server again. It’s not a 360 degree turnaround. It’s a partial turnaround. A hybrid solution to make up for the cloud’s defects. The cloud is great. But the enormous growth of hybrid cloud technologies only proves that it still has a long way to go before it’s fast and secure. “In the end, customers and users don’t even care about the cloud,” says Maples. “They just have a job to do. It’s performance and convenience that an all-or-nothing cloud approach can’t deliver.” Can’t we all admit that embarrassing truth?

Cloud computing bad – no one uses

Cloud computing is unreliable

CCA ’15 (Cloud Computing Advices, Cloud Computing advices is the one of the best leading cloud computing blogs, where you can access the tutorials on cloud computing, breaking news, security issues, top cloud computing providers, certifications, training programs and jobs opportunities for freshers and experienced IT Professionals, “Cloud Computing Disadvantages”, http://cloudcomputingadvices.com/disadvantages-cloud-computing/, 2/20/2015)//HW

Negative effects and Disadvantages of cloud computing:¶ The Greenpeace NGO announces, in its 2010 report on the ecological impact of the IT industry, the negative impacts of cloud computing.In the below list you can see the 5 disadvantages of cloud computing as per the report.¶ 1.The main drawback is the security issues related to storing of confidential information in the cloud. As all information is available via internet if taken to the cloud, there may be concerns with breach of confidential information.¶ 2.There is a tendency for some firms to lose their control over the piled up information in the cloud.¶ 3.The legal issues including ownership of abstraction on the location data of cloud computing.¶ 4.Cloud computing also poses problems in terms of insurance, especially when a company submits an operating loss due to failure of the supplier. Where one company covering a risk, the insurance company offering the cloud architecture takes more, slowing sharply compensation.¶ 5.The customer service of cloud computing becomes dependent on the quality of the network to access this service. No cloud service provider can guarantee 100% availability.

Lots of drawbacks to cloud computing – people won’t switch over

Ward ’11 (Susan, business writer and experienced business person; she and her partner run Cypress Technologies, an IT consulting business, providing services such as software and database development, “5 Disadvantages of Cloud Computing”, About Money, http://sbinfocanada.about.com/od/itmanagement/a/Cloud-Computing-Disadvantages.htm, 11/8/2011)//HW

5 Disadvantages of Cloud Computing¶ 1) Possible downtime. Cloud computing makes your small business dependent on the reliability of your Internet connection. When it's offline, you're offline. If your internet service suffers from frequent outages or slow speeds cloud computing may not be suitable for your business. And even the most reliable cloud computing service providers suffer server outages now and again. (See The 10 Biggest Cloud Outages of 2013.)¶ 2) Security issues. How safe is your data? Cloud computing means Internet computing. So you should not be using cloud computing applications that involve using or storing data that you are not comfortable having on the Internet. Established cloud computing vendors have gone to great lengths to promote the idea that they have the latest, most sophisticated data security systems possible as they want your business and realize that data security is a big concern; however, their credibility in this regard has suffered greatly in the wake of the recent NSA snooping scandals.¶ Keep in mind also that your cloud data is accessible from anywhere on the internet, meaning that if a data breach occurs via hacking, a disgruntled employee, or careless username/password security, your business data can be compromised.¶ Leaving aside revelations about the NSA, switching to the cloud can actually improve security for a small business, says Michael Redding, managing director of Accenture Technology Labs. "Because large cloud computing companies have more resources, he says, they are often able to offer levels of security an average small business may not be able to afford implementing on its own servers" (Outsource IT Headaches to the Cloud (The Globe and Mail).¶ 3) Cost. At first glance, a cloud computing application may appear to be a lot cheaper than a particular software solution installed and run in-house, but you need to be sure you're comparing apples and apples. Does the cloud application have all the features that the software does and if not, are the missing features important to you?¶ You also need to be sure you are doing a total cost comparison. While many cloud computer vendors present themselves as utility-based providers, claiming that you're only charged for what you use, Gartner says that this isn't true; in most cases, a company must commit to a predetermined contract independent of actual use. To be sure you're saving money, you have to look closely at the pricing plans and details for each application.¶ In the same article, Gartner also points out that the cost savings of cloud computing primarily occur when a business first starts using it. SaaS (Software as a Service) applications, Gartner says, will have lower total cost of ownership for the first two years because SaaS applications do not require large capital investment for licenses or support infrastructure. After that, the on-premises option can become the cost-savings winner from an accounting perspective as the capital assets involved depreciate.¶ Cloud computing costs are constantly changing, so check current pricing.¶ 4) Inflexibility. Be careful when you're choosing a cloud computing vendor that you're not locking your business into using their proprietary applications or formats. You can't insert a document created in another application into a Google Docs spreadsheet, for instance. Also make sure that you can add and subtract cloud computing users as necessary as your business grows or contracts.¶ 5) Lack of support. In These Issues Need to be Resolved Before Cloud Computing Becomes Ubiquitous, (OPEN Forum) Anita Campbell writes, "Customer service for Web apps leaves a lot to be desired -- All too many cloud-based apps make it difficult to get customer service promptly – or at all. Sending an email and hoping for a response within 48 hours is not an acceptable way for most of us to run a business".
