News of Cloud is everywhere, and its predominance in IT is a foregone conclusion. In fact, the push to adopt Cloud has been so strong that risks inherent in this model have largely been ignored The recent economic turmoil and the promise of Cloud leading a renaissance of the tech sector are shaping the perspective and appetite for Cloud rather than the readiness of the technology itself. Cloud is a powerful tool for mobilizing data; however, there are no regulations, standards, or assurances of data protection from a technical perspective Major breaches at Google, Salesforce. om, and Amazon, have exposed the fragility of the Cloud delivery model, and the fundamental issues of data security, privacy, and standards that have yet to be addressed. Though price points gained in Cloud can be significant, businesses should weigh advantages against the hidden costs of compromised data Analyst sentiment seems to be the sole voice of reason. Principal analysts from Forrester, Gartner, and Yankee cite major security concerns with Cloud.
Hackers have also highlighted the vulnerabilities of Cloud and issued a manifesto of mayhem against it (Black Hat 2009 – Clobbering the Cloud by SensePost) Assessing your organization’s readiness for Cloud should include the evaluation of hybrid models, hybrid architectures, integration constraints, and innovative data protection methods, that will offer the best approach for business adoption Consider the direct business benefits of Cloud for your company and your individual business needs, weighing against security and privacy concerns.
In the more immediate future, look toward applications focused on innovative data protection methods, enabling organizations to utilize Public Cloud in a private manner Adoption Haste Security Risks Expert Views Opportunity Key Takeaways December 2010 | Copyright © 2010 Grail Research, LLC 3 Foundations of Cloud Computing Foundations of Cloud Computing Obstacles and Considerations Foundations of Cloud Computing Obstacles and Considerations Future of Cloud Future of Cloud Cloud is an evolution, merging virtualization, grid, utility, and web standards “ Cloud is an evolution.
It coalesces grid, utility, virtualization and web standards into a delivery paradigm. The difference is each of these components are building blocks that solve the specific point problems of abstracted, on-demand, distributed processing – Tony Bishop (Founder and CEO, Adaptivity) I don’t think it’s a revolution as much as it’s an evolution. If you want to really say what kicked this thing off, virtualization was a big precursor to Cloud…I think “Cloud” is a little bit overused right now. I look at it as the evolution of the data center, to do more scalable processing and computing – Ping Li (Partner, Accel Partners)

We did a focus group around 12 months ago and they pretty much took the mickey out of Cloud. It was seen as unrealistic and CIOs weren’t considering it. What’s even more of a surprise is that in a short period of 12 months, we’ve seen Cloud go from a bit of a joke to a number two priority on the plate of CIOs today, and a very serious consideration that they are taking on board – Paul Harapin (Director, ComputersOff. rg and Ex-MD, Vmware) Defining Cloud Computing Definition Foundations of Cloud Computing Obstacles and Considerations Future of Cloud “Cloud computing is a model for enabling convenient, on-demand network access to a shared 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 interaction. ” – Peter Mell and Tim Grance (NIST) Essential Characteristics

About 21% of those folks involved in cybersecurity, their agencies are unaware about cloud computing, and 34% of the respondents in total weren’t familiar with the cloud. That is the real key-take away that awareness around the cloud as it relates to trust and security needs to continue to be increased” – Melvin Greer (Chief Strategist, Cloud Computing, Lockheed Martin) “…the biggest security threat for cloud computing is lack of awareness about cloud security among the IT Pro’s” – Scott C. Sanchez, CISSP (Security and Privacy Officer, ScaleUp
Cloud) “Public cloud services are generally not providing as much customization as customers want, but the cloud model is gaining popularity both among users who want to sidestep their companies’ IT departments, and from small businesses that want to get out of the IT business” – Tim O’Brien (Director, Platform Strategy Group, Microsoft) “Cloud solutions won’t come in a box, nor are traditional internal IT technologies and skills apt to seamlessly spin up mission-ready cloud services. Neither are cloud providers so far able to provide custom or ‘shrinkwrapped’ offerings that conform to a specific enterprise’s situation and needs” – Dana Gardner (President and Principal Analyst, Interarbor Solutions) “People are going to want to move data around, they’re going to want to ask clouds to do things for them . We don’t have any inter-cloud standards.
There’s a whole raft of research work still to be done and protocols to be designed and standards to be adopted that will allow people to manage assets” – Vint Cerf (Co-designer of the TCP/IP, VP and Chief Internet Evangelist, Google) “When customers are looking to adopt cloud services, they want services that follow highest standards, even though such services may follow better standards than their existing infrastructure” – Bernard Golden (CEO, HyperStratus) Awareness and understanding of cloud computing is limited to a small set of IT professionals B Requires Customized Solutions Requires Cloud Computing Standards There is a gap between customer requirements and existing cloud computing solutions in the market Note: Comment and Views include key snippets Source: Sysomos Software Tool; CIO Website; SysCon Website; Ulitzer Website; CloudNod Website December 2010 | Copyright © 2010 Grail Research, LLC 10 “ C Cloud computing is still evolving in terms of welldefined adoption/integration standards

The concept of computing resources as a utility is gaining traction among SMBs; however, the economic model offered by Cloud service providers has yet to prove its strength of scalability to enterprise customers “ “In the past, energy-efficient performance and connectivity have defined computing requirements. Looking forward, security will join those as a third pillar of what people demand from all computing experiences” – Paul Otellini (CEO, Intel) “It’s a big win for smaller companies to leverage the cloud because you are really saving a lot–it is really avoiding a large, up-front investment. Five years ago, we would have had to build out a data center and the sheer cost of that would have made it much more difficult to launch our business.
In a traditional data center, we would need an IT person to rack the system, maintain the servers, and own the hardware, So rather than hiring someone, we now have software developers that are writing on a very flexible platform that vendor maintains” – Oliver Friedrichs (CEO, Immunet) “Right90 didn’t start its business using third-party infrastructure, but the cost savings and flexibility of Cloud services beckoned. Last year, the company moved out of its data centers in Calgary, Ontario and San Francisco, California and adopted Amazon EC2 with backup to servers located at the firm’s own offices.

Drivers of Adoption Expert Views Foundations of Cloud Computing Obstacles and Considerations Future of Cloud Key Takeaways A Economic Downturn “ “In part, this can be explained by macroeconomic factors, The financial turbulence of the last 18 months has meant every organization has been scrutinizing every expenditure. An IT solution that can deliver functionality less expensively and with more agility (remembering that time is money) is hard to ignore against this backdrop” – Ben Pring (VP, Gartner Research) The economic downturn has forced businesses to become leaner, which in turn has fuelled the adoption of cost-effective Cloud service models B
Technology Advancements “Server technology is in the middle of a renaissance where it is driving Cloud advancements and Cloud is, in turn, changing servers. Cloud-based ‘scale issues’ will continue to change how servers and software for them are built for years to come” – Steve Ballmer (CEO, Microsoft) The success of virtualization and Internet bandwidth availability has positioned Cloud services as a potential market opportunity Demand Expectation Note: Comment and Views include key snippets Source: Sysomos Software Tool; CIO Website; SysCon Website; Ulitzer Website; CloudNod Website December 2010 | Copyright © 2010 Grail Research, LLC 13 “ C In technical terms, cloud computing offers elasticity, pay-as-you-go rather than capital-intensive investment, and no long-term resource commitments. In business terms, cloud computing means low cost of opportunity experimentation, high agility to respond to changing business conditions, and the ability to direct capital investment toward core business activities”– Bernard Golden (CEO, HyperStratus) Cloud’s on-demand model allows companies to scale up (or down) as they rapidly restructure to meet market requirements, with a pay-as-you-go model instead of taking on the capital expenses of traditional IT infrastructure Barriers to Major Adoption Insights Foundations of Cloud Computing Obstacles and Considerations Future of Cloud
Industry experts believe that there is apprehension among potential Cloud customers about security and data privacy. Other major concerns include complexity in the integration of cloud-based systems and adherence to regulatory/compliance frameworks 1 Security and Data Privacy 2 Integration with Cloud-Based Systems Expert Views 3 Regulatory and Compliance Issues “ “Security has been identified as the most significant issue associated with cloud computing adoption” – Melvin Greer (Chief Strategist, Cloud Computing for Lockheed Martin) “At this initial stage, the applications and data being processed in clouds are predominantly non-sensitive, and the Cloud services offer minimal or only generally available security.
The cloud offerings themselves are proprietary computing islands, with few standards and only limited possibilities for interoperability” – RSA (Security Division of EMC), White paper1 “I am 100 percent responsible and accountable for all technology and every shred of data that moves in and out of my company, and don’t want IT to be seen as “the say-no people”, but end users may not foresee the difficulties of meshing new products with existing technology. On-premise, we have technology standards. Nothing like that exists in the cloud. If business users adopt these things, we CIOs are challenged in IT to figure out how to integrate [them] with the rest of our world” – Don Goin (CIO, Santander Consumer) In certain cases, compliance will be impossible, It is difficult to take full responsibility for who can access data, who sees it and how it is stored, since the premise of the Cloud is that customers don’t necessarily need to know or care where their data is” – Jim Haskin (SVP, Websense inc) “There is an issue that’s looming that hasn’t really been discussed or addressed yet. That is the role of governance for companies that are consuming the services versus the role of governance for companies that are providing the services. On some level, companies are going to be both consumers and providers of cloud services” – Joe McKendrick (Independent Analyst and ZDNet Blogger) Note: 1The Role of Security in Trustworthy Cloud Computing; Comment and Views include key snippets Source: Sysomos Software Tool; CIO Website; SysCon Website; ComputerWorld Website December 2010 | Copyright © 2010 Grail Research, LLC 14 “ Addressing Security Concerns Insights
Information Security Secure sensitive or confidential information Foundations of Cloud Computing Obstacles and Considerations Future of Cloud IT managers don’t believe that current cloud computing solutions are at par with on-premise infrastructure solutions. To address this concern, service providers need to offer: Authentication Properly identify and authenticate users before granting access to services Data Location Identify the exact physical location of information assets Independent Audits Conduct independent compliance checks on services provided Infrastructure Access Limit access to physical infrastructure where applications are deployed
Data Reliability Prevent data loss and maintain integrity Customer Apprehensions and Expert Views Key Takeaways There is lack of visibility on legal and compliance standards, and potential customers have limited clarity on where and how the data is stored, and who can access the data “ “Having core components, such as storage, compute, security, and so on, outsourced to other cloud providers could mean that your data and application processing exists across many different physical providers, and the risk of outages, compliance issues, and data leaks increases dramatically” – David Linthicum (CTO, Bick Group) (2010 Survey on participants in DEF CON) “…. elief from the hackers, that cloud vendors are not doing enough to address the security issues of their services; hackers have identified vulnerabilities in current cloud technology” – Barmak Meftah (Chief Product Officer, Fortify Software) “When vulnerabilities are detected they can be managed more rapidly and uniformly. Cloud security is able to respond to attacks more rapidly by reducing the time it takes to install patches on thousands of individual desktops or hundreds of uniquely configured on-premise servers” – Mike Bradshaw (Director, Google Federal, Google Inc. ) “Attempts to infiltrate or disrupt online service offerings grow more sophisticated as more commerce and business occurs in this venue” – John Howie (Senior Director, Microsoft)

Innovation flexibility at low operating expense and no capital expenditure On-demand scalability to synchronize with market dynamics Ability to access information regardless of location Allows large enterprises to focus on core business activities instead of IT infrastructure Lower cost of power, space, and data center maintenance by taking non-critical services out of data centers Risk of hardware and software obsolescence transferred to Cloud service provider “ “Companies such as AllenPort and ARC offer SMEs good software at affordable prices with the flexibility to adjust usage on an as-needed basis. The service model meets the financial needs of SMEs while protecting them from the risks of nongenuine software” – Charl Everton (Anti-Piracy Manager, Microsoft SA) They (Mid-sized companies) face rapidly changing markets and need to avoid being locked into a capital investment or any particular mode of operations.
The call option that cloud computing represents — the ability to change in the future without a penalty — is critical to a midsized company trying to succeed in a world of giant competitors and disruptive change” – Bernard Golden (CEO, HyperStratus) CONS Security, privacy, and compliance concerns Network latency hinders application performance Cost of hardware rapidly decreasing — can be a future concern Complex integration of legacy systems with Cloud systems an obstacle; needs can be greater than current Cloud capabilities Increase in security threats due to adoption of Public Cloud Legal compliance and regulatory issues if operations in multiple countries Highly skilled IT staff and sunk investments in existing hardware infrastructure may also act as a deterrent to move to Cloud I would argue, however, that if you have existing IT investment, or you have requirements that push beyond the limits of today’s cloud computing technology or business models, you should consider not choosing at all” – James Urquhart (Blog Network Author, CNET) “What holds back large companies is, in a sense, their success with the previous generation of computing. Because they could invest in the old model, they’ve now got an installed base of hardware and a large, top-notch technical staff on hand. There’s pressure on these businesses to justify the sunk cost of their hardware infrastructure, so they tend to more toward a vision of private cloud computing” – Bernard Golden (CEO, HyperStratus)

A Framework for Estimating the Value of Cloud Computing” by Markus Klems, Jens Nimis and Stefan Tai; SmartDataCollective Website December 2010 | Copyright © 2010 Grail Research, LLC 19 How Green is Cloud? Insights Foundations of Cloud Computing Obstacles and Considerations Future of Cloud Experts see the potential of cloud computing for “Green IT” through efficient power consumption; however, skeptics claim that there is no comprehensive framework to assess the value proposition of “Green Cloud” Green Lining to Cloud Cloud computing providers strive to maximize the performance of their operations and can achieve higher utilization rates than in-house data centers Cloud data centers can be developed at strategic locations, or integrated with renewable sources of energy
Skepticism and Uncertainty According to a survey by Rackspace Hosting1, only 20% believe that hosted solutions play a role in making their firm greener. An additional 34% of those customers are currently trying to evaluate the efficiencies and ‘greenness’ of Cloud. As more and more enterprises opt for Cloud, data centers end up using more electricity to run computers, as well as meet back-up and cooling demands. Experts believe that Cloud companies may choose output over environmental considerations in the future • Hewlett-Packard developed a wind-cooled data center in England • Google’s data center in Saint-Ghislain, Belgium, functions without chillers
Expert Views “In theory, a shared resource like Amazon or Google’s public clouds can have higher utilization and thus greater power efficiency. Locate your cloud data center close to a green power source, like a hydro plant, and you can minimize transmission line power losses and be even greener”– Marc Hamilton (VP of Cloud Computing Sales, Sun) “I’m sure that if you were to compare a traditional data center deployment to a near exact replication in the Cloud you’d find the Cloud to be more efficient, but the problem is there currently is no way to justify this statement without some kind of data to support it” – Reuven Cohen (CTO, Enomaly Inc. “So, in a sense, the “greenness” of Cloud computing is a kind of Schroedinger’s box problem today, in which we won’t know the actual savings to the environment until someone actually observes–or measures–it” – James Urquhart (Product Marketing Manager of Cloud Computing, Cisco Systems) “Cloud doesn’t save power but displaces it. Ultimately, roughly the same power is drawn from the grid, just by different companies. So it’s no greener. Cloud is more about dealing with companyspecific issues than planetary ones” – Andy Lawrence (Research Director, 451 Group) Key Takeaways Experts maintain that Cloud is greener than individual data centers, however, there is a long road ahead in substantiating “
Cloud allows companies to scale down IT resources when demand is low, reducing their carbon footprint significantly Green cloud as a concept depends on the ability of Cloud providers to meet their increasing demands through renewable sources of energy Note: 1 Based on 167 customer responses from email Survey conducted by Rackspace Hosting globally in 2009; Comment and Views include key snippets Source: SysCon Website; ComputerWeekly Website; GreenBiz Website; Rackspace Hosting Survey Report; Greenpeace Report; CIO Website December 2010 | Copyright © 2010 Grail Research, LLC 20 “ Future of Cloud Foundations of Cloud Computing Obstacles and Considerations Foundations of Cloud Computing Obstacles and Considerations Future of Cloud Future of Cloud
Over the last few years, start-ups and small businesses have proposed innovative solutions to mitigate the risks associated with cloud computing, and are competing with leading players in the Cloud space “ “I believe that Cloud computing is a powerful trend – the next platform shift in computing. It will profoundly change the way organizations do their computing. Proof is in the fact that major vendors like IBM, Google, and Microsoft are investing tens of billions of dollars in building out their Cloud infrastructures. Those who characterize Cloud computing as mostly hype have short memories. It was barely a decade ago that many people characterized the Internet as mostly hype” – Bernard Golden (CEO,
HyperStratus) “So, in terms of the first movers and the environment now, it’s going to look very different. Anybody who carved out some space right now and some lead in the market in Cloud shouldn’t feel too comfortable about their position, because there are companies we don’t even know about at this point, that are going to be fairly pervasive and have a lot to say about IT five years from now” – Jim Reavis (Executive Director of Cloud Security Alliance (CSA), and President, Reavis Consulting Group) “Password resetting and other security mechanisms in the Cloud are always going to be a weak link, as long as userfriendliness comes ahead of security in Cloud computing beauty stakes.
Expecting regular joes to whip out a twofactor authentication device for use with a Cloud-driven service just isn’t realistic.

The system will address the issue of security by adding SLA-level guarantees, thus increasing Cloud adoptability IT identifies four key Cloud storage characteristics: confidentiality, integrity, write-serializability (ensuring data is updated in the right order), and read freshness (reads most recently updated data file). The proposed Cloud storage system, CloudProof, can detect and prove security violations to these properties The advantage is that hackers cannot gain information from encrypted data, however, they can still infer information from Cloud access patterns Foundations of Cloud Computing Obstacles and Considerations Future of Cloud
Nippon Telegraph & Telephone Corporation and Mitsubishi – Advanced Encryption Scheme Nippon Telegraph and Telephone Corporation, and Mitsubishi Electric Corporation have developed a new encryption system that provides complex and “fine-grained data transmission/access control” This scheme uses a mathematical approach called “dual pairing vector spaces” to allow confidential information access The encryption scheme is proposed to be used in cloud computing and other advanced network services to attain secure environments CloudProof will detect and prove security violations across four storage characteristics The Advanced Encryption Scheme applies advanced logic in encrypting and decrypting to provide a secure Cloud environment IBM – Homomorphic Encryption Scheme IBM is working on an encryption system that will allow the searching of data in an encrypted format “The point is to allow others to manipulate your encrypted data without revealing it to them. For example, in cloud computing you want to store your encrypted data files out on the cloud, so that you can access it from anywhere.
But you would also like to be able to search your data with some combination of keywords, then just decrypt the query results…” “The usefulness of the scheme is still limited by the fact that, as more operations are performed, successive encrypted answers degrade, becoming ‘dirty’” – Craig Gentry (Researcher, IBM) Trend Micro – SecureCloud Trend Micro has launched an encryption solution called SecureCloud This solution is provided through a single web portal and supports Vmware, Eucalyptus, and Amazon Elastic Compute Cloud SecureCloud uses key management technology and standard encryption services to provide data security and privacy to Cloud users.
Unlike other Cloud security services, the encryption keys remain exclusively with the user “Security has been one of the greatest inhibitors to Cloud Computing adoption. Now, as Cloud Computing takes shape and enterprises are starting to put data in the Cloud, security must evolve to protect and control the data” –Steve Quane (Chief Product Officer, Trend Micro – Cupertino, CA) When operational, the Homomorphic Encryption Scheme will be able to search, sort, and process encrypted data SecureCloud gives enterprises ultimate control over the data Source: Microsoft Website; Mitsubishi Electric Website; SmartTechnology Website; SysCon Website; WorldCadAccess Website; InformationManagement Website; Microsoft Research Paper Abstract (Raluca A.

An ecosystem of Cloud service evaluators, aggregators, and integrators will emerge to address growing customer concerns and potential business opportunities. Cloud computing presents an opportunity to monetize open source applications/tools A Improved Compliance and Service-level Agreements “ “Some compliance requirements demand that relevant data be encrypted both at rest and in transit. Many of the cloud providers do not support that” – Chenxi Wang (Ph. D. , Principal Analyst, Forrester) “Customers will care more about service level agreements than the brand name of technology components. …Integration will emerge as the key enabler and choke point” – R. ‘Ray’ Wang (Partner, Altimeter Group) B Evolving Business Models Integrated/ Customized Service Offerings
IT managers are optimistic about Software as a Service (SaaS) being the key source of future efficiency gains “Service providers will compete not just on price, but scalability, efficiency, and SLAs” – Stephen Fosket (Recipient of Microsoft MVP award) “…Emerging Cloud based business models like gaming as a service, content driven clouds, cloud computing can help monetize open source software…” – Krishnan Subramanian (Chief Technologist/Advisor, CloudsDirect) Mid-size companies are more likely to adopt Cloud services over the next few years, especially Infrastructure as a Service (IaaS) C “Single function clouds will evolve to deliver a suite of service offerings to their clients or be acquired by others providing multiple cloud service offerings, as clients will not want to manage an endless stream of cloud service providers for every workload they outsource” – Ray DePana (Industry Consultant, NSF1) “From a strategic differentiation point of view, organizations must enhance product offerings with services, improve the customer experience with loyalty top of mind, and tailor personalized experiences that support self-service options and mobility” – R. ‘Ray’ Wang (Partner, Altimeter Group)
Potential customers will be more concerned about flexibility, control, and growth from cloud computing services, rather than security By 2012, cloud computing is predicted to gain widespread acceptance with corporate data centers as 20% of businesses globally are expected to own no IT assets Note: 1National Science Foundation Initiative on Computational Thinking; Comment and Views include key snippets Source: SoftwareInsider Website; Ulitzer Website; GestaltIt Website ;Forrester Report; SysCon Website; InfoWorld Website, Gartner Report; LinkedIn December 2010 | Copyright © 2010 Grail Research, LLC 26 “ Cloud – The Way Ahead? Foundations of Cloud Computing Obstacles and Considerations Future of Cloud
The evolution of Cloud marks a fundamental shift in our relationship with electronic assets and our access to that data and information The Cloud offers great promise; however, companies seeking to implement cloud-based applications have concerns about the security and privacy of public cloud providers. Until providers offer sufficient clarity and assurance on these topics, their customers will implement data protection and security methods on their own which enable them to overlay a private cloud functionality on top of the public cloud offering1 Hybrid architectures that offer encryption of data at the local or client level, prior to transmission to the Cloud may offer a path forward for business consumption, thereby combining the best of on-premise functionality with that of hosted solutions for these on-demand services
If you are evaluating a Cloud initiative, always assess your company’s readiness, measuring the cost and benefit for your business within the context of the competitive landscape. Consider: What are the direct business benefits of Cloud for my company? Why would I ‘rent’ rather than ‘own’? Will a Cloud solution support my business needs, or am I losing functionality for a perceived price benefit? How does my solution provider’s roadmap align with my business needs? How are my Cloud solution providers establishing standards and maintaining the security and privacy of my information and by extension, my clients’ information? What are my competitors doing in this space? Are they pursuing private, public, or hybrid initiatives? Note: 1Grail interviews with Bernard Golden (CEO, HyperStratus); Chenxi Wang (Ph. D.
