Cloud complexity: The need for resilience
Cloud computing has helped reduce costs
and boost productivity at many organisations,
but its broader use brings both benefits and
risks. These risks extend well beyond security
breaches into a lack of oversight of complex,
often fragmented systems that, if not
managed well, limits an organisation’s ability
to capture new opportunities and to adapt
and respond to new technology or regulatory
controls.
How should Chief Information Officers
leverage the cloud’s potential? How can they
fortify their company’s continuity and agility in
the cloud? What key challenges must be
overcome to succeed on this journey? Like all
big changes, a successful shift to cloud
computing requires a shift in both mindsets
and strategies, processes and partnerships
across and outside a company.
This report by the Economist Intelligence Unit
(EIU) on behalf of Sungard Availability Services
explores these and other critical questions as
companies expand their cloud use.

Preface
In March of 2016, the EIU, for a research programme sponsored by Sungard Availability Services, polled
304 executives evenly dispersed across France, the United Kingdom and the United States on their
organisational resilience and technology adoption. Respondents hail from a number of industries,
including IT and technology (15%), financial services (13%), professional services (8%), manufacturing
(7%) and 15 other sectors (collectively 57%). Those polled hold the titles of chief information officer
(50%), senior vice president (12%), vice president (15%) or head of IT (23%). The companies they
represent earn between $50m and $500m (45%), or more than $500m (55%) in annual revenue.

Cloud complexity: The need for resilience
Organisations today operate in an
increasingly interconnected and information-
rich world. Innovations like big data and
dynamic pricing create unprecedented
opportunity for businesses to launch novel
products and services, conquer new markets
and better engage customers. But the same
developments bring new risks and
challenges—from security breaches and
service interruption to managing fragmented
IT systems, vast data troves and the dizzying
speed of change.
Cloud computing is perhaps the most
prominent example of recent disruptive
technologies that are reshaping corporate
strategies and IT capabilities. Cloud use is now
almost universal among organisations—and
only expected to grow. In the EIU survey, 78% of
executives agree that their use of cloud
computing will increase in the next three years
(see Figure 1); nearly two-thirds (65%) say that
more than half of their organisations’ systems
are now cloud-based versus the just 6% who say
that one-quarter or less of their systems are in the
cloud. “Companies are no longer considering
whether to migrate to the cloud, but rather
what … and how best to migrate,” notes Tanuja
Randery, president, UK & Ireland at French
electronics conglomerate Schneider Electric.
The move to the cloud is a logical one.
Cloud solutions help organisations add new IT
capabilities and applications at lightning
speed, often at a lower lifetime cost. But the
cloud can introduce more external players
and potential breakage points that demand
responses to both innovation and regulation
at a faster pace than many IT organisations
can meet.

Cloud complexity: The need for resilience
Against this backdrop of change and
uncertainty, “organisational resilience” is
emerging as a critical lever of a successful
cloud expansion. BSI, the business standards
company, defines resilience in its newly
published BS 65000 standard as the ability to
both quickly bounce back from a major
disruption and to “anticipate, prepare for,
respond and adapt to events—both sudden
shocks and gradual change” to survive and
prosper.
In fact, as Lyndon Bird, technical director at
BSI points out in a recent Continuity Central
article, the field of Business Continuity
Management is reorienting its focus to
organisational resilience. Business continuity
strives to prepare an organisation for effective
responses to sudden, major disruptions with
minimal business impact. The business
continuity agenda has also traditionally
resided within the risk and compliance
function which has struggled to gain broader
buy-in from other functions—primarily because
it has been considered by other functions
across the broader organisation as “not their
problem”.
Organisational resilience, by contrast,
alters the management posture from a
reactive one to proactively anticipating and
preparing for future disruption—and not just
sudden cataclysmic ones, but also gradual
strategic shifts. This more complex and
difficult goal is intricately linked to an
organisation’s overall business strategy and
requires broader mobilisation of corporate
capabilities across an organisation—from
human resources managers to department
heads to those who oversee supply chains.
They will need to organise everything ranging
from business processes to internal controls to
capture value and mitigate the risk inherent
in cloud opportunities. Thus, the resilience
agenda is reaching the highest levels of an
organisation.

Cloud complexity: The need for resilience
The same shift in executive focus is taking
place within cloud computing. As executives’
experience and comfort level with the cloud
grow, they are refocusing their attention
beyond continuity onto the strategically
important objective of resilience.
This trend is clearly shown in the EIU survey.
Nearly three-quarters (72%) of survey
respondents say the importance of
organisational resilience will increase over the
next three years (see Figure 2), a sentiment
expressed even more strongly in the US (78%).
Notably, the more advanced a company is
in its adoption of cloud technology, the
stronger its focus on resilience appears to be.
Respondents in the EIU survey who believe
their organisation is ahead of its competitors in
cloud adoption are nearly three times as likely
as the rest to also say they are ahead in their
organisational resilience to technology risk.
Indeed, according to respondents in the EIU
survey, companies that are ahead of the
competition in cloud adoption also tend to
outperform their competitors in profitability
and innovation. (See Figure 3).
On the other hand, the focus on resilience
does not look to be linked to a company’s
cloud exposure. Survey respondents with just
1-24% of their IT assets in the cloud were just as
likely to say that resilience will grow in
importance as those who say that 75-99% of
their IT systems are in the cloud (68% vs 70%).
To be sure, this is not a shift away from
business continuity, which, like cloud
computing, also focuses on the availability
and security of IT assets—even more so in the

age of the cloud. Security risks still top the list
of cloud computing challenges identified by
respondents in the EIU survey (see Figure 4),
and are the most frequently named barrier to
further technology adoption.
The most commonly cited risks are security
breaches and leaks of confidential
information (53% say they are extremely or
moderately concerned about this risk),
disruptions caused by cyber-attacks (52%)
and potential failure to deliver product or
services (46%). Two recent examples of
high-profile security failure cases: breaches of
federal workers’ personnel files at the US
government’s Office of Personnel
Management and patient record breaches at
CareFirst Networks.
“Both cloud providers and enterprises are
getting smarter about security,” observes Ms
Randery of Schneider Electric. Indeed, no
executive interviewed by the EIU for this report
could recall any recent major disruption or
incident pertaining to data security or service
availability within their cloud systems. This
reflects, perhaps, a growing view that data,
systems and processes may be more secure
with a large cloud provider than within a firm’s
own walls.

Cloud complexity: The need for resilience
“It is much easier today to provide 100%
uptime, so the cloud is actually a better
place for security,” seconds Dom Guinard,
co-founder and CTO of technology
company EVRYTHNG. He notes that cloud
providers such as Amazon and Microsoft
have invested heavily to address the security
and stability challenges of their cloud
environments, so companies are better off
offloading these risks and responsibilities to
large-scale providers. “On-premise is more
risky,” Mr Guinard cautions.
As the use of the cloud expands, executives
are taking a more holistic and sophisticated
approach, embedding the narrower goal of
business continuity within the broader, more
challenging and strategically relevant
objective of organisational resilience. Ms
Randery sums it up elegantly: “Resilience … is
not just about uptime and security; it is
increasingly about agility, speed,
multiplication and being more innovative.”

Cloud complexity: The need for resilience
As organisations shift their focus from
continuity to resilience, they will need to
master the five key capabilities that follow.
Although some of these building blocks are
rooted in business continuity, they will need to
be reshaped and reprioritised inside and
outside a company to adapt to the new
opportunities and risks that the cloud brings.
1. Specialised and regulatory requirements.
Migrating to one company-wide cloud
solution with broad functionalities and an
impact on all corporate functions is often
difficult or impractical. A cloud system for a
particular functional area (such as research &
development), for discrete events (like games
or conventions) or for a specific geography
may be wiser—with tailored services and
safeguards to better meet data sovereignty,
security or latency needs. This is also easier for
organisational change management
because cloud capabilities address core
demands.
To meet more stringent demands for
oversight and control, Ms Randery predicts
that specialised but adaptable solutions that
serve particular functions or geographies will
grow. “Specialised is easier to outsource,” she
notes. “It facilitates a greater level of
migration and creates greater organisational
resilience.”
But the push towards specialisation
demands different approaches based on, for
example, specific risks or regulations.
In retail, for instance, the regulatory focus is
on maintaining the privacy and confidentiality
of customer data and compliance with the
Payment Card Industry Data Security
Standards (PCI DSS) to protect credit
cardholder information.
PCI DSS compliance is also critical for
financial services, as is adherence to the US
Gramm-Leach-Bliley Act, which requires
financial institutions to establish standards for
protecting the security and confidentiality of
their customers’ non-public personal
information.
In healthcare, the US federal Health
Insurance Portability and Accountability Act
(HIPAA) requires healthcare organisations to
maintain the confidentiality of electronic
health information that can be linked to an
individual patient (also known as electronic
protected health information, or ePHl). As
Kristin Darby, chief information officer at
Cancer Treatment Centers of America
(CTCA), notes, HIPAA/ePHI compliance in the
cloud is a particular challenge.
“Many specialised application vendors are
simply forcing their existing desktop versions
onto a cloud platform, without having
ensured the integrity and interoperability of
data, functionalities and workflows,” Ms Darby
notes. The main barrier to greater cloud
2 The building blocks of cloud resilience

Cloud complexity: The need for resilience
adoption among healthcare companies
today is the “shortage of cloud providers who
can meet the industry’s unique requirements
around compliance and availability and can
provide single tenancy at an affordable cost”,
she adds.
2. Systems integration and governance.
Today’s cloud ecosystem is a mix of cloud
types, multiple cloud providers, many cloud
instances and specialised systems and
applications native to individual departments.
“We are concerned about application sprawl
and loss of organisational resilience due to the
ease of use and implementation of cloud-
based solutions, especially when done without
enterprise awareness,” cautions Ms Darby.
The “sprawl” Ms Darby references, if
unchecked, will pose a significant resilience
risk to organisations and has pushed CTCA to
add more process controls to contain this
growth. As Ms Randery of Schneider Electric
points out, “Data fragmentation is good from
a risk perspective, but who’s watching all
that? When you have multiple cloud
providers, how do they talk to each other?”
More-advanced cloud users are already
recognising, and many are addressing, the
importance of oversight, connections and
accountability. Respondents who say their
organisations are ahead of competitors in
organisational resilience are more likely to
prioritise their efforts to strengthen internal
processes and integrate new and legacy
systems (see Figure 5).
3. Data and process re-engineering. Among
the greatest challenges companies face after
moving assets to the cloud is connecting
existing data sets, business processes and
workflows to the newly adopted technology.
First, executives must ensure that the data
and systems they are moving are clean,
organised and ready for migration. “How do
you outsource a mess? What … if you don’t
fully understand your own existing data and
legacy systems?” Ms Randery of Schneider
Electric asks.
More important, for greater resilience,
proper alignment and flexing of the day-to-
day workflow and business processes are
critical to capture and monetise the
efficiencies, productivity and increased
resilience cloud computing promises. As Harsh

Sinha, vice president, Engineering of money
transfer company TransferWise, points out,
“Companies need to re-architect to move to
the cloud.” Often the heavy lifting required
may prompt a company to keep legacy
systems in house—or, sometimes, to shut them
down altogether.
Indeed, lack of processes is a top
challenge to cloud adoption for one-fifth of
respondents in the EIU survey. To shore up
resilience after cloud expansion, companies
will need to work closely with partners to
ensure that everyday processes seamlessly
connect with the new cloud interface. Done
well, the payoff is clear. Between 26% and 40%
(see Figure 6) of EIU survey respondents say
improved processes are a top benefit of their
cloud use, perhaps attributable to the greater
access, speed, agility and collaboration the
cloud enables.
4. Ongoing service and maintenance. As with
any new IT platform or service, moving to the
cloud is not a one-and-done deal. Keeping
systems updated, running and bug-free, and
responding to user queries, feedback and
service needs are perhaps more important
than the initial migration. “You have to make
sure you have enough people doing the right
things: patching systems, overseeing the
physical security of IT assets, linking your
organisation with that of the cloud provider,”
says Mr Guinard of EVRYTHING.
This upkeep and customer service can be a
significant challenge. But addressing this early
can pay dividends. “Cloud can be a little bit
impersonal,” remarks Ms Randery of Schneider
Electric. “On-the-ground support for users is
very important.” Ensuring the right level of
service and support both in-house and
through a cloud provider for both
implementing cloud solutions and shoring up
organisational resilience is critical.
5. People and skill sets realignment.
Successful adoption of any technology
ultimately hinges on the human element. The
right mix of skills, a smooth transition to new
technology and a prompt embrace of a more
agile and evolving process and culture by
stakeholders will help companies reap the
expected value from new cloud
implementations.
“Technology is easier,” cautions Mr Sinha of

Cloud complexity: The need for resilience
TransferWise. “The bigger resilience challenge
is organisational. Companies need to retool
their people for cloud computing. It requires
significant change management.” But the
extent of the challenge very much depends
on an organisation’s culture.
“You need different people,” seconds Mr
Guinard of EVRYTHING. System administrator
skills were most valued before; now
developers who manifest agility and speed
are in demand. Unfortunately but
understandably, these skills are also valued by
start-ups and are costly. Longer term, to build
resilient cloud-based capabilities, companies
will need to better understand the human
needs of those who are implementing and
maintaining their cloud-based strategy.

Cloud complexity: The need for resilience
The rapid march into cloud computing has
increased and will continue to increase the
complexity and speed of change of IT
ecosystems. In this often fragmented and
always fluid environment, a different
mindset— shifting focus from continuity to
resilience—is needed to capture the
efficiency, agility and economic gains
promised by the cloud; anticipating or
responding to negative disruptions will also be
required.
IT executives must rethink strategies,
re-engineer operating models, retool talent
and reinvent governance and decision-
making. To do so, they will need to engage
more stakeholders across an organisation.
They will need to forge partnerships to better
anticipate and address risks, to avoid
disruption and to adapt to dynamic market,
technology and regulatory environments.
