  • 3. Forrester ConsultingPrivate Cloud – It’s More Than Just VirtualisationExecutive SummaryCloud will be part of your organisation’s future, regardless of your company size, your current distribution ofworkloads across various deployment types, or your current position on the viability of cloud services. Although therisk of leading a potentially unsuccessful cloud initiative may seem too great, the risk of pushing back and notadvancing your organisation to embrace the cloud is even greater. IT teams that aren’t developing cloud environmentsand cloud skillsets today may soon find themselves outdated and of less value to the organisation. Now is the time tostart making that transformation to ensure longer-term success for your company and your IT organisation. Thechallenges are determining how to incorporate cloud into strategic plans and managing risk while ramping upexperience on the team. Looking at typical enterprise cloud road maps, Forrester finds that an internally based privatecloud is a popular approach, but many struggle with setting up this new environment in a way that maximises benefitsand positions these organisations for the customer-focused IT future.In March 2012, NetApp commissioned Forrester Consulting to conduct a survey of 265 enterprise IT decision-makerswho self-identified as having private cloud deployments. In this study, Forrester asked about the functionality of theirenvironment, the barriers and risks associated with the move to private cloud, how they justified the investment, topbenefits experienced, and the effect of this on the business/IT relationship. This report reveals the findings of this study,focusing on two core topics to help enterprises navigate the private cloud world to a successful future: • Level-setting on current private cloud market trends. Forrester sees a gap between perceived private cloud adoption and usage and actual adoption rates. Many organisations struggle to identify where cloud goes above and beyond virtualisation and what to expect in terms of barriers and benefits. • Best practices: Get the most out of your private cloud. Based on the NetApp commissioned study and Forrester’s own research, we have identified three key best practices used by the most successful enterprise cloud teams: 1) They partner with the business from the start; 2) they think like a service provider; and 3) they don’t reinvent the wheel. Follow these three principles on your own cloud journey.Level-Setting On Current Private Cloud Market TrendsIf you’ve attended any IT conferences in the past two years, you’re most likely to have heard any number of stories fromCIOs about their private cloud efforts and the benefits they’ve experienced. You may even feel behind or overwhelmedby the fast pace of adoption if you haven’t finalised your cloud strategy or started deployment. But in our experience,you’re not behind the curve yet. Forrester interviewed some of these self-proclaimed private cloud adopters and foundupon examination that few of these environments actually provide a fully functional private cloud. It’s common forenterprises to enhance an existing virtual environment with some level of improved management or automation. Andthis isn’t limited to just those that have chosen to build their own custom cloud solution. Many are using commerciallyavailable solutions that include all of the functionality required to deploy a private cloud, but they have elected not toenable some of the private cloud functionality or are restricting complete automation. Forrester defines cloudcomputing as:A standardised IT capability (services, software or infrastructure) delivered in a pay-per-use, self-service way.Page 2
  • 4. Forrester ConsultingPrivate Cloud – It’s More Than Just VirtualisationFew enterprises incorporate all these components. Furthermore, claims of improved cost savings more often than notinclude benefits experienced through server virtualisation or consolidation and are not an isolated view of what toexpect when moving from a mature virtual environment to a private cloud. What’s the reality? Private cloud does offerenterprises significant value, but typically not through hard cost savings. The value comes primarily from agility andoptimising your most valuable asset – your workforce. To better understand the current private-cloud state, Forrestersurveyed 265 enterprise IT decision-makers who self-identified as having private-cloud deployments. This surveyhighlighted five key trends that Forrester sees in the private cloud space today: • Missing functionality is common among today’s private cloud adopters. Forrester surveyed self-identified private cloud owners about how this environment goes above and beyond a traditional virtual environment. We found that many of these environments fell short of a full-feature private cloud: Of those surveyed, 56% tracked use of cloud resources by account or user, 45% had a self-service portal, 50% had automated the provisioning process, and only 39% had a chargeback system in place – all key private cloud components (see Figure 1).Figure 1Many Adopters Are Missing Key Capabilities But Plan For Future Implementation “Please indicate the server virtualisation operations tasks you are implementing in your private cloud environment today.” Expanding/upgrading Implemented but no plans on expanding Planning to implement within the next 12 months Planning to implement in more than 12 months Interested but no plans Track use of cloud resources by account or user 32% 24% 22% 9% 9% Policy-based automation for deployment and 25% 25% 26% 11% 10% management of the private cloud environment Self-service portal for end users such as developers 26% 19% 31% 10% 8% to deploy, manage and remove virtual machines Chargeback to business user based on actual virtual 20% 19% 21% 17% 13% machine usage in a period Base: 265 IT decision-makers reporting current use of private cloudSource: A commissioned study conducted by Forrester Consulting on behalf of NetApp, March 2012 • Pre-integrated solutions got closer to cloud. Today there are many different ways to create an internal private cloud. Most organisations look to cloud experts to help create their cloud solution in varying degrees. Forrester found that 43% use an external service provider to build their cloud environment, 14% use a full pre-integrated package solution, and another 13% use a software-only solution on top of existing resources. Only 31% built their cloud solution from scratch (see Figure 2). Forrester found that those using a packaged solution (either software only or software/hardware) got the closest to a true cloud environment. 1Page 3

Forty-nine per cent said reduced cost is a key reason they invested in private cloud (see Figure 3). Many roll up the benefits of consolidation and server virtualisation into private cloud savings rather than seeing these as different deployments. In fact, when asked what was used to justify a private cloud deployment, 61% said they were using expected savings gained through virtualisation and consolidation to justify the investment. • . . . but the top benefit experienced thus far is faster resource access for development and testing. Despite the focus on cost reduction for both justifying investment and measuring success, the greatest actual benefit experienced thus far is greater agility for test and development staff. Forrester found that 84% of respondents experienced substantial benefits from increased access to resources for test and development (see Figure 4). • Integration with existing systems is the biggest private cloud challenge. Forrester found that 40% believed that integration with existing systems was one of the top three challenges of moving to private cloud. This is a challenge that is not limited to (or more substantial for) out-of-the-box software solutions. Forrester spoke with a few early adopters that explicitly built their own solution in an attempt to lessen integration challenges that they associated with pre-packaged software solutions. In this survey, we found that those using an out-of-the-box software solution did not report any greater challenge with integration than those that built their own internal solution. 2 Other top challenges included application performance (30%), infrastructure availability (24%), and pricing model and governance (24%) (see Figure 5).Page 4

Those that approach private cloud like any other enterprise IT deployment typicallystruggle with maintaining the environment, differentiating it from other internal environments, and justifying theinvestment. Forrester has identified three key best practices that lead to greater private cloud success: • Team with the business from the start. Instead of just delivering this new set of capabilities to the business, engage with the business early to ensure that these capabilities meet the businesss needs and that users are likely to use them rather than circumventing IT for their own preferences. • Think like a service provider. When it comes to private cloud, you are the service provider, so act and think like one and not like a traditional enterprise IT shop when it comes to cloud strategy and meeting business needs. Don’t stop at virtualisation – incorporate all of the key components required for a complete private cloud rather than settle for lower returns and an unsuccessful attempt at meeting agile business needs internally. It’s all too common to see virtualised environments painted as cloud that leave out core components because IT does not see these as key features, doesn’t trust the end users with automated permission-based access, or won’t reconsider legacy policies and protocols. • Don’t reinvent the wheel. Instead of building a solution from scratch and re-architecting your entire environment, enlist help from an array of external resources, whether it be full consulting services to help scope, design and build the environment, or a software-only solution on top of existing resources to deliver a pervasive portal with standard features and functionality that your end users will be looking for.Page 6
  • 8. Forrester ConsultingPrivate Cloud – It’s More Than Just VirtualisationBest Practice No. 1: Team With The Business From The StartIts most likely that you’ve identified users within your organisation who push the boundaries of every corporatepolicy by bringing in new mobile devices and using various unauthorised cloud capabilities. These users go byvarious names: shadow IT users, rogue IT workers or simply empowered users whose managers value results morethan process. This is just the beginning. Business users no longer rely on IT-provided tools and equipment, given theabundance of tools/services focused on user experience at little to no cost. More and more users will start joiningthese ranks – and that’s a good thing. It’s these empowered users who look to get their job done better and faster,delivering higher value to the business. The problem? IT isn’t involved, and these users don’t understand the securityrisks and implications of these tools and won’t change their practices if it means restricting the agility orfunctionality of these services. For IT, this means helping users do this safely without holding them back, markingthe beginning of the consumerisation of IT and a significant change in the way IT functions and delivers its services.This frames how you must approach private cloud.It’s all about meeting the needs of these business users. IT commonly makes the mistake of building an environmentbased on what it thinks the business wants and then expects the business to use it once the environment is complete.Often, these environments end up unused and empty. Rather than trying to predict the interface, experience andfunctionality that your users want, work with them directly from the beginning and design/select a solution that fitstheir actual needs/wants. Those much more engaged with the business experienced a greater reduction in unauthorisedpublic cloud use. In our study, 48% of those more engaged with the business experienced significant benefits beyondexpectations compared with the 16% that didn’t engage with the business more than usual. In the long term, itimproves the relationship between IT and the business, making this future engagement easier.But this approach isn’t the typical approach today. Many enterprises build an environment for IT (without any businessengagement) with two priorities: 1) Stamp out public cloud use, and 2) benefit from the significant savings that aretypically associated with cloud services. The first is dependent on meeting customer needs and providing incentives tochange behaviour – a new concept for most infrastructure and operations professionals today. Unfortunately, the latterpriority is a far stretch. In fact, hard cost savings can be very limited given the necessity to still plan for peak andeconomies of scale. With private cloud, you have less opportunity to combine a variety of workloads on a sharedinfrastructure than a service provider that supports multiple industries and time zones, making it difficult to maximiseresource utilisation while maintaining the same uptime. Although savings are possible, your initial deployment isunlikely to deliver significant hard savings over and above those of a consolidated, virtualised environment. The realbenefits are business enablement through agile resources, improved management of IT resources, and reduction in ITtime spent maintaining ongoing operations.Forty-nine per cent of enterprises we surveyed invested in private cloud with hopes of reducing costs. Unless you’rewrapping virtualisation and consolidation savings or reduced workforce into your private cloud figures, the hard costsavings aren’t going to be significant. Get the most out of private cloud by approaching from the right mindset – designor build this solution for and with the end user to take full advantage of the business enablement benefits, and berealistic about the potential hard cost savings: • Start private cloud planning with the business. Get the business involved today. Regardless of whether you’ve started your planning, strategy development, vendor selection or actual deployment already, begin this conversation as soon as possible. Ideally you’ll look to inventory existing cloud use, gain insight into key customer experience preferences, and identify priorities while taking note of the additional services or features that need to be applied on the back end and abstracted from the experience of the user.Page 7
  • 9. Forrester ConsultingPrivate Cloud – It’s More Than Just Virtualisation • Design a rollout cycle that reflects business needs and wants. As is common with most application rollouts, it can’t be done all at once. If you’re just starting along the path of greater engagement with the business, the business is going to want to see key features and functions from the start or it will lose faith in the system quickly. Design your rollout to prioritise the core functionality the business seeks early on, while enhancing its features long-term. • Ensure a smoother transition to your solution. Start by asking users what theyre currently using and get a feel for what that user experience and functionality looks like. Use this as a benchmark if you’re developing your own solution. If you’re looking at pre-built solutions, investigate whether its possible to use the same solution along with the typical mix of best-of-breed solutions and existing vendor partnerships. If not, make sure that you include the end users in the selection process so that they get to demo the product and provide feedback that will influence the final selection. This is a key part of the process; if users don’t like their user experience, they won’t use it. • Align metrics to business enablement. Forrester found that 47% of respondents used operational cost reduction as a metric for private cloud success, whereas only 29% tracked time-to-provision as a metric. Not only does this set false expectations but it also designs the environment around IT concerns rather than serving the business. When Forrester surveyed developers and other business users, we consistently found that speed-to-market and agility were top priorities. Ensure that this is reflected in the metrics for measuring success if minimising circumvention is a priority. For example, some of the more successful private cloud adopters today use business enablement measurements, such as time-to-provision as key metrics for benchmarking their cloud environments.Best Practice No. 2: Think Like A Service ProviderIf you’ve built a private cloud, you’re a service provider. And more importantly, the move towards IT consumerisationrequires that you start acting like one in order to better serve your customers (the business). But it isn’t an easy change.ITs goals are frequently focused on uptime and maintaining the status quo, and organisational challenges restrict whatyou can do differently. At the same time, the business pressures IT to start doing things differently by threateningcircumvention, making it a priority to get a successful cloud up and running quickly. Where do you start? The sameplace that successful vendors start – shaping the product to meet the customers’ needs and wants and workingbackwards from there while understanding the capabilities and user experience offered by the competition. Although itseems logical to compare this new internal environment with other internal deployment types, that’s not actually thecompetition in the customer’s eyes. The alternative option that promises agile resources at low costs through a self-service portal is public cloud. To get cloud right, you must create an environment as similar to public cloud as possibleto incentivise your customers to use this solution instead of alternatives.Start off on the right foot by getting to a fully functional private cloud that includes all core capabilities, rather thansimply applying a cloud label to a virtualised environment. It’s all too common for enterprises to rename existingenvironments and/or pick and choose certain private cloud capabilities while self-identifying as having private cloud.The pressure to get to cloud and provide a public cloud alternative makes this approach very tempting. Many justifythis move by claiming that the business doesnt require these capabilities or cite internal legacy limitations and policiesthat prevent them from treating cloud differently. Either way, it doesn’t solve the problem that leaving out corecomponents does affect the customer and that the alternative option, public cloud, will be more appealing. Forrestersplit survey respondents into true private cloud deployments and those missing core capabilities to better understandthe differences in success reported by each group. 3 Forrester found that those with true private cloud implementationsexperienced seven key benefits (see Figure 6).Page 8
  • 10. Forrester ConsultingPrivate Cloud – It’s More Than Just VirtualisationFigure 6Benefits Of Building A Full-Featured Private Cloud Solution Much more business engagement. Those with full cloud deployments were twice as likely to experience much more engagement between the business and IT after cloud implementation – with 28% of respondents with true private cloud environments reporting much more engagement with the business, versus the 14% of those with missing capabilities. Success at getting new business capabilities to market faster. Eighty-one per cent of full cloud deployments reported that they were able to get new business capabilities to market faster, compared with the 68% of those that were missing core components. Greater IT team efficiency. Eighty-seven per cent of full cloud deployments reported greater IT team efficiency post-cloud deployment, whereas only 74% report the same if missing core components. Competitive advantage in its industry. Seventy-three per cent of full private cloud deployments reported that cloud gave them a competitive advantage in their industry, compared with the 64% that claimed this of non-full deployments. Reduced costs. Eighty-three per cent of full cloud deployments reduced costs deployment, whereas 74% of those missing components reported the same. Reduced unauthorised use of public cloud. Dissuading shadow IT users is a common driver for implementing private cloud deployments. Those with full deployments reported a 71% success rate at reducing this, compared with the 63% that reported this same benefit despite missing key cloud components. Reduced time spent provisioning and decommissioning resources. Seventy-nine per cent of full cloud deployments reported reduced time spent provisioning and decommissioning resources, compared with the 71% with missing components that reported this.

  • 11. Forrester ConsultingPrivate Cloud – It’s More Than Just VirtualisationGet the most out of your private cloud deployment by building a true private cloud environment that is as much likepublic cloud as possible, and then measure its success compared with public cloud rather than other internalenvironments. Key features include: • Real self-service access. Providing self-service access of resources is one of the basic requirements of cloud, and yet 49% of the respondents we surveyed don’t create or enable these features. And those who do only grant this self-service access to the cloud administration team or a small group of users rather than to those who actually require the resources. These business users typically follow standard enterprise IT protocol by submitting a ticket that is then fulfilled by IT. Not providing self-service access adds time to the process, providing little incentive for users to use your environment rather than a public cloud. • Standardised and automated processes and provisioning. Another key cloud feature is full standardisation and automation, but only 50% of self-identified enterprise private clouds actually have this implemented today. And even those that claim implementation often don’t have a fully automated provisioning process. Typically, networking, security checks, permissions and approvals are all still manual processes. This missed step translates into slowed provisioning time – attenuating a potential 15-minute time frame to hours or days. Although this seems minute compared with other internal deployments, this is dramatically slower than provisioning in a public cloud. • Incentivised decommissioning. Chargeback is the most effective way to incentivise users to utilise IT resources efficiently. But given existing policies, billing systems and other operational challenges, chargeback is out of reach for most enterprises. In fact, the reported 39% with chargeback implementations and the 21% planning to adopt within the next year is unusually high for enterprises. In Forrester’s Q3 2011 hardware survey, only 14% of respondents had chargeback or plans to implement within the next year. 4 If chargeback is out of reach for your organisation, use other ways to put cloud resources in business terms. Some alternative options include: showback (showing prices associated with services but not charging the user for them), allocation-based resources, soft expiry dates (continuous warnings at deadlines), and hard expiry dates (deletion at deadline). The closer you can get to chargeback and/or showback models, the more efficiency you’ll experience. • A pricing model comparable with the public cloud model. If you’re able to take the chargeback route, it’s tempting to start building out a complicated pricing structure that accurately reflects use and total spending in order to ensure you’re meeting ROI for these resources. Realistically, it will be almost impossible to figure out a model that accurately measures power use, short-term use of the resources (rather than continued use throughout its life), and total man-hours spent on this for a certain increment of time. But with private cloud, it’s all about the expectations that have been set by the public cloud. Scrap the complicated models, and pattern your approach on pricing models that have been proven to work in the public cloud. At the end of the day, the business user will be comparing your services with public cloud options and will make a decision accordingly.Page 10
  • 12. Forrester ConsultingPrivate Cloud – It’s More Than Just VirtualisationBest Practice No. 3: Don’t Reinvent The WheelBuilding a private cloud can be time- and resource-intensive – but it doesn’t have to be. Today, there are varioussolutions available that can help enterprises get to private cloud faster, with fewer resources, and with greater resultsthan possible alone. Case in point: Forrester found that 31% of enterprises surveyed built their private cloud themselves,a process that requires significant programming hours from a team of developers who are likely to be new to cloudservices and required capabilities. The 43% who used an external service provider to build their solution were far morelikely to have a self-service portal and to have actually reduced unauthorised use of public cloud services aboveexpectations. 5 Likewise, the 27% using a pre-integrated solution (either software-only or software/hardware) were farmore likely to have completely automated provisioning and a self-service portal and were more successful at connectingwith the business. 6 The resulting environments are stronger and more in-line with long-term IT goals, but even moreimportantly, getting assistance reserves your most valuable asset, your IT staff, for mission and/or business focusedtasks. These are some common ways to leverage existing cloud expertise: • Software-only solutions. Multiple vendors offer software-only solutions that sit on top of existing resources (i.e. hardware, hypervisor management tools, and automation capabilities) to help manage and control the cloud environment. These solutions typically have some level of hardware agnosticism but still require some integration with existing solutions to get up and running. Out-of-the-box, it includes a web-based user interface for self- service provisioning of resources with role-based permissions, giving cloud administrators the ability to assign different user rights and set capacity limits. • Pre-integrated hardware/software solutions. Commonly referred to as “cloud-in-a-box” solutions, these hardware/software packages are pre-integrated and optimised for private cloud environments. If you’re an organisation looking to invest in significant infrastructure upgrades specifically for a private cloud, consider using these solution types rather than piecing together a solution yourself. • Consulting services to build and/or manage. When it comes to building a private cloud environment, there are challenges along the way even if you’re using a software or software/hardware solution. Integration and management may require expertise that you don’t have on your staff. When working with consulting firms, enterprises can experience a higher success rate while benefiting from expertise that they don’t have to hire long term. • Consulting services focused on strategy and process. Most enterprises struggle with organisation structure and strategy rather than figuring out infrastructure components or a new technology. Several consulting agencies specifically focus on helping organisations develop a solid cloud strategy that considers organisational structure and process changes that are required for deploying and managing a private cloud environment. • Training programmes and certifications. Beyond consulting services, software and hardware, your team can gain real value from training programmes and certification programmes. Many IT teams leverage a mix of real- time experience, public cloud experimentation and training programmes to ramp up cloud skills sufficiently in order to support and/or build a private cloud environment. There are various certification programmes available through vendors, vendor sponsorship and/or university courses that will get your cloud team off to the right start. This is an important investment to save the organisation substantial man-hours while providing valuable takeaway skills for your cloud team.Page 11
  • 13. Forrester ConsultingPrivate Cloud – It’s More Than Just VirtualisationKEY TAKEAWAYS: MAXIMISE YOUR PRIVATE CLOUD BY INCLUDING ALL CORE FUNCTIONALITYYou’ve got time to create a good strategy – so get to full functionality. What you hear about private cloud adoption atconferences is often not a full view of what enterprises are actually doing today – in fact, real private clouds are few and farbetween. If you’re looking to take advantage of the cloud for agility or are trying to provide an alternative to the publiccloud, we’ve found that those who implemented all core capabilities were far more successful. Instead of rushing into aprivate cloud investment, make sure you’re taking the right steps and getting it right the first time and setting the rightexpectations. As you start this journey, keep these three best practices in mind: 1. At the end of the day. . . it’s all about your customer. If there’s one thing to take away from this report, its that the business is going to be in control. They’ve transitioned from accepting what was delivered to seeking better options and maximising their time and productivity. The new role of IT is less about keeping everything up and running and more about delivering a better, simplified user experience to the end user. This means utilising automation and outsourcing to reduce this existing workload so that you can focus on tasks that are more critical to the business and be closer to the revenue generators. Cloud is a great opportunity to start this journey, and its success ties heavily into your ability to do this – so start the conversation today. 2. Remember, you’re the service provider. Many admins responsible for deploying private clouds come from traditional enterprise IT heritage and act as caretakers – they support the needs of the business with a primary goal of protecting the business from itself with rules, restrictions and set tools that meet IT guidelines. But this strategy no longer works. The business has already started to circumvent these rules, and for the first time, IT must “compete for customers”. If reducing unauthorised use of public cloud or enabling the business with agile infrastructure is the goal, you’ll need to start acting like a cloud provider and adjust to the way the business wants to consume IT services. This means incentivising your customers to use a private cloud solution rather than the public cloud and constantly comparing your solution with this alternative. 3. But that doesn’t mean you have to reinvent the wheel. Just because you’re now a service provider, it doesn’t mean that you have to build a custom solution from the ground up. There are lots of tools, services, programmes, certifications and integrators with cloud experience that can help your IT team get to cloud faster so that you can focus on the more difficult organisational and strategic portions of this implementation.Page 12

Forrester ConsultingPrivate Cloud – It’s More Than Just VirtualisationAppendix A: Survey Methodology And DemographicsIn this study, Forrester conducted an online survey of 265 organisations with 500 or more employees in the US (105),Canada (27), Great Britain (36), Germany (35), France (35) and Australia (27), to evaluate current use of virtualisationand private cloud. Survey participants included decision-makers with responsibility/influence on cloud decisions intheir organisation (CIO, VP infrastructure, cloud architect, infrastructure architect, and VP of IT) who reported currentuse of private cloud. Questions provided to the participants asked about the functionality of their environment, and thebarriers and risks associated with the move to private cloud, how they justified the investment, top benefits experienced,and the effect of this on the business/IT relationship. The study was conducted in March 2012.Figure A1Industry Breakdown Of Respondents “Which of the following most closely describes your industry?” Financial services and insurance 24% Manufacturing 18% Business/professional services 15% Utilities and telecommunications 11% Public sector (government, etc.) 10% Retail and wholesale trade 7% Transport and logistics 4% Media, entertainment and leisure 4% Other, please specify 6% Base: 265 IT decision-makersSource: A commissioned study conducted by Forrester Consulting on behalf of NetApp, March 2012Figure A2Level Of Experience Using Private Cloud “What is your firm’s level of experience with private cloud?” Using private cloud for both development and 33% production purposes for between 6 and 12 months Using private cloud for both development and 32% production for more than 12 months Using private cloud but use for test and 18% development purposes ONLY Using private cloud for both development and 16% production purposes for less than 6 months Base: 265 IT decision-makersSource: A commissioned study conducted by Forrester Consulting on behalf of NetApp, March 2012Page 13

Fifty-nine per cent of pre-built solutions had completely automated provisioning andprocesses compared with the 47% of those IT-built cloud solutions claiming complement automation. Similarly, 53% ofpre-built solutions reported self-service access for business users compared with the 39% of IT-built solutions. In termsof chargeback, 45% of pre-built had already adopted chargeback versus the 36% of IT-built solutions.2 Forrester asked respondents about their top three problems with the cloud today and compared differences betweensolution types adopted. We found that across the board, integration was the top problem regardless of solution type,with 41% of those with pre-built solutions, 37% of custom solutions built by service providers or consultants, and 42%of solutions that were built by IT.Page 14
  • 16. Forrester ConsultingPrivate Cloud – It’s More Than Just Virtualisation3 For this cut, Forrester split respondents into those that incorporated the main functions necessary to achieve a privatecloud. Those with a “full functionality” responded that they had implemented the following server virtualisationmanagement capabilities: track use of cloud resources by account user, policy-based automation for deployment andmanagement of private cloud environment, and self-service portal for end users such as developers to deploy, manageand remove virtual machines. Those that had not implemented all of the components were classified as missing corefunctions.4 Only 14% of the 804 North American and European IT decision-makers that were using x86 server virtualisation(from a variety of enterprises across industries polled in our Forrsights Hardware Survey, Q3 2011) said that they hadimplemented chargeback. Source: Forrsights Hardware Survey, Q3 2011, Forrester Research, Inc.5 Forrester reviewed the actual benefits experienced by adopters of various solution types and found that those that useda pre-packaged solution reported greater-than-expected benefits of reduction in unauthorised cloud usage. Forty-sevenper cent of those using an external service provider or consultant to build this environment similarly experiencedhigher-than-expected reduction in unauthorised public cloud use. Only 21% of those that built their own cloudreported this.6 Forrester found that those using a pre-integrated solution got the closest to a true cloud environment. This wasevident in multiple crosstabs completed. Some examples are as follows: 1) A higher percentage of pre-integratedsolutions (59%) implemented automation than those built internally (47%); 2) a higher percentage of pre-integratedsolutions (53%) implemented a self-service portal than those built internally (39%); 3) a higher percentage of pre-integrated solutions (45%) implemented chargeback than those built internally (36%); 4) those using a pre-integratedsolution (44%) reported that they invested in private cloud partially for empowerment of users compared with thoseusing an external service provider to build the solution (29%) and those built internally by IT (31%); 5) those using apre-integrated solution (44%) reported higher-than-expected benefits in reduced unauthorised usage of public cloud(reported 4 or 5) versus the 37% of those using a solution built by an external service provider and the 21% of those thatbuilt this solution themselves.Page 15
