Executive Summary
Cloud will be part of your organisation’s future, regardless of your company size, your current distribution of
workloads across various deployment types, or your current position on the viability of cloud services. Although the
risk of leading a potentially unsuccessful cloud initiative may seem too great, the risk of pushing back and not
advancing your organisation to embrace the cloud is even greater. IT teams that aren’t developing cloud environments
and cloud skillsets today may soon find themselves outdated and of less value to the organisation. Now is the time to
start making that transformation to ensure longer-term success for your company and your IT organisation. The
challenges are determining how to incorporate cloud into strategic plans and managing risk while ramping up
experience on the team. Looking at typical enterprise cloud road maps, Forrester finds that an internally based private
cloud is a popular approach, but many struggle with setting up this new environment in a way that maximises benefits
and 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-makers
who self-identified as having private cloud deployments. In this study, Forrester asked about the functionality of their
environment, the barriers 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. 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 Trends
If you’ve attended any IT conferences in the past two years, you’re most likely to have heard any number of stories from
CIOs about their private cloud efforts and the benefits they’ve experienced. You may even feel behind or overwhelmed
by 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 found
upon examination that few of these environments actually provide a fully functional private cloud. It’s common for
enterprises to enhance an existing virtual environment with some level of improved management or automation. And
this isn’t limited to just those that have chosen to build their own custom cloud solution. Many are using commercially
available solutions that include all of the functionality required to deploy a private cloud, but they have elected not to
enable some of the private cloud functionality or are restricting complete automation. Forrester defines cloud
computing as:

A standardised IT capability (services, software or infrastructure) delivered in a pay-per-use, self-service way.

Few enterprises incorporate all these components. Furthermore, claims of improved cost savings more often than not
include benefits experienced through server virtualisation or consolidation and are not an isolated view of what to
expect when moving from a mature virtual environment to a private cloud. What’s the reality? Private cloud does offer
enterprises significant value, but typically not through hard cost savings. The value comes primarily from agility and
optimising your most valuable asset – your workforce. To better understand the current private-cloud state, Forrester
surveyed 265 enterprise IT decision-makers who self-identified as having private-cloud deployments. This survey
highlighted 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).

• 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. 1

• Almost half are looking to private cloud for cost reduction. . . 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).

Best practices: Get the most out of your private cloud
Building a private cloud isn’t easy. Those that approach private cloud like any other enterprise IT deployment typically
struggle with maintaining the environment, differentiating it from other internal environments, and justifying the
investment. 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 business's 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


Best Practice No. 1: Team With The Business From The Start
It's most likely that you’ve identified users within your organisation who push the boundaries of every corporate
policy by bringing in new mobile devices and using various unauthorised cloud capabilities. These users go by
various names: shadow IT users, rogue IT workers or simply empowered users whose managers value results more
than process. This is just the beginning. Business users no longer rely on IT-provided tools and equipment, given the
abundance of tools/services focused on user experience at little to no cost. More and more users will start joining
these 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 security
risks and implications of these tools and won’t change their practices if it means restricting the agility or
functionality of these services. For IT, this means helping users do this safely without holding them back, marking
the 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 environment
based 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 and
functionality that your users want, work with them directly from the beginning and design/select a solution that fits
their actual needs/wants. Those much more engaged with the business experienced a greater reduction in unauthorised
public cloud use. In our study, 48% of those more engaged with the business experienced significant benefits beyond
expectations compared with the 16% that didn’t engage with the business more than usual. In the long term, it
improves 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 business
engagement) with two priorities: 1) Stamp out public cloud use, and 2) benefit from the significant savings that are
typically associated with cloud services. The first is dependent on meeting customer needs and providing incentives to
change behaviour – a new concept for most infrastructure and operations professionals today. Unfortunately, the latter
priority is a far stretch. In fact, hard cost savings can be very limited given the necessity to still plan for peak and
economies of scale. With private cloud, you have less opportunity to combine a variety of workloads on a shared
infrastructure than a service provider that supports multiple industries and time zones, making it difficult to maximise
resource utilisation while maintaining the same uptime. Although savings are possible, your initial deployment is
unlikely to deliver significant hard savings over and above those of a consolidated, virtualised environment. The real
benefits are business enablement through agile resources, improved management of IT resources, and reduction in IT
time spent maintaining ongoing operations.

Forty-nine per cent of enterprises we surveyed invested in private cloud with hopes of reducing costs. Unless you’re
wrapping virtualisation and consolidation savings or reduced workforce into your private cloud figures, the hard cost
savings aren’t going to be significant. Get the most out of private cloud by approaching from the right mindset – design
or build this solution for and with the end user to take full advantage of the business enablement benefits, and be
realistic 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


• 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 they're 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 it's 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 Provider
If you’ve built a private cloud, you’re a service provider. And more importantly, the move towards IT consumerisation
requires that you start acting like one in order to better serve your customers (the business). But it isn’t an easy change.
IT's goals are frequently focused on uptime and maintaining the status quo, and organisational challenges restrict what
you can do differently. At the same time, the business pressures IT to start doing things differently by threatening
circumvention, making it a priority to get a successful cloud up and running quickly. Where do you start? The same
place that successful vendors start – shaping the product to meet the customers’ needs and wants and working
backwards from there while understanding the capabilities and user experience offered by the competition. Although it
seems logical to compare this new internal environment with other internal deployment types, that’s not actually the
competition 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 possible
to 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 than
simply applying a cloud label to a virtualised environment. It’s all too common for enterprises to rename existing
environments 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 justify
this move by claiming that the business doesn't require these capabilities or cite internal legacy limitations and policies
that prevent them from treating cloud differently. Either way, it doesn’t solve the problem that leaving out core
components does affect the customer and that the alternative option, public cloud, will be more appealing. Forrester
split survey respondents into true private cloud deployments and those missing core capabilities to better understand
the differences in success reported by each group. 3 Forrester found that those with true private cloud implementations
experienced seven key benefits (see Figure 6).

Page 8


Figure 6
Benefits 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.

Get the most out of your private cloud deployment by building a true private cloud environment that is as much like
public cloud as possible, and then measure its success compared with public cloud rather than other internal
environments. 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


Best Practice No. 3: Don’t Reinvent The Wheel
Building a private cloud can be time- and resource-intensive – but it doesn’t have to be. Today, there are various
solutions available that can help enterprises get to private cloud faster, with fewer resources, and with greater results
than 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 cloud
services and required capabilities. The 43% who used an external service provider to build their solution were far more
likely to have a self-service portal and to have actually reduced unauthorised use of public cloud services above
expectations. 5 Likewise, the 27% using a pre-integrated solution (either software-only or software/hardware) were far
more likely to have completely automated provisioning and a self-service portal and were more successful at connecting
with the business. 6 The resulting environments are stronger and more in-line with long-term IT goals, but even more
importantly, getting assistance reserves your most valuable asset, your IT staff, for mission and/or business focused
tasks. 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.

KEY TAKEAWAYS: MAXIMISE YOUR PRIVATE CLOUD BY INCLUDING ALL CORE FUNCTIONALITY
You’ve got time to create a good strategy – so get to full functionality. What you hear about private cloud adoption at
conferences is often not a full view of what enterprises are actually doing today – in fact, real private clouds are few and far
between. If you’re looking to take advantage of the cloud for agility or are trying to provide an alternative to the public
cloud, we’ve found that those who implemented all core capabilities were far more successful. Instead of rushing into a
private cloud investment, make sure you’re taking the right steps and getting it right the first time and setting the right
expectations. 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, it's 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.

Appendix A: Survey Methodology And Demographics
In 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 virtualisation
and private cloud. Survey participants included decision-makers with responsibility/influence on cloud decisions in
their organisation (CIO, VP infrastructure, cloud architect, infrastructure architect, and VP of IT) who reported current
use of private cloud. Questions provided to the participants asked about the functionality of their environment, and the
barriers 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.

Forrester investigated whether solutions with pre-built solutions or IT-built cloud solutions reported higher adoption
of key cloud capabilities. Fifty-nine per cent of pre-built solutions had completely automated provisioning and
processes compared with the 47% of those IT-built cloud solutions claiming complement automation. Similarly, 53% of
pre-built solutions reported self-service access for business users compared with the 39% of IT-built solutions. In terms
of 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 between
solution 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.

For this cut, Forrester split respondents into those that incorporated the main functions necessary to achieve a private
cloud. Those with a “full functionality” responded that they had implemented the following server virtualisation
management capabilities: track use of cloud resources by account user, policy-based automation for deployment and
management of private cloud environment, and self-service portal for end users such as developers to deploy, manage
and remove virtual machines. Those that had not implemented all of the components were classified as missing core
functions.

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 had
implemented chargeback. Source: Forrsights Hardware Survey, Q3 2011, Forrester Research, Inc.

Forrester reviewed the actual benefits experienced by adopters of various solution types and found that those that used
a pre-packaged solution reported greater-than-expected benefits of reduction in unauthorised cloud usage. Forty-seven
per cent of those using an external service provider or consultant to build this environment similarly experienced
higher-than-expected reduction in unauthorised public cloud use. Only 21% of those that built their own cloud
reported this.
6
Forrester found that those using a pre-integrated solution got the closest to a true cloud environment. This was
evident in multiple crosstabs completed. Some examples are as follows: 1) A higher percentage of pre-integrated
solutions (59%) implemented automation than those built internally (47%); 2) a higher percentage of pre-integrated
solutions (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-integrated
solution (44%) reported that they invested in private cloud partially for empowerment of users compared with those
using an external service provider to build the solution (29%) and those built internally by IT (31%); 5) those using a
pre-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 that
built this solution themselves.
