3.4. Risks and Challenges
Several of the best analytical billow accretion challenges pertaining mostly
to billow consumers that use IT assets amid in accessible clouds are
presented and examined.
Increased Aegis Vulnerabilities
The affective of business abstracts to the billow agency that the responsibility
over abstracts aegis becomes aggregate with the billow provider. The remote
usage of IT assets requires an amplification of assurance boundaries by the
cloud customer to board the alien cloud. It can be difficult to
establish a aegis architectonics that spans such a assurance boundary
without introducing vulnerabilities, unless billow consumers and cloud
providers appear to abutment the aforementioned or accordant security
frameworks—which is absurd with accessible clouds.
Another aftereffect of overlapping assurance boundaries relates to the
cloud provider’s advantaged admission to billow customer data. The admeasurement to
which the abstracts is defended is now bound to the aegis controls and
policies activated by both the billow customer and billow provider.
Furthermore, there can be overlapping assurance boundaries from different
cloud consumers due to the actuality that cloud-based IT assets are
The overlapping of assurance boundaries and the added acknowledgment of data
can board awful billow consumers (human and automated) with
greater opportunities to advance IT assets and abduct or accident business
data. Figure 3.9 illustrates a book whereby two organizations
accessing the aforementioned billow account are appropriate to extend their respective
trust boundaries to the cloud, consistent in overlapping assurance boundaries.
It can be arduous for the billow provider to action aegis mechanisms
that board the aegis requirements of both billow service

Overlapping assurance boundaries is a aegis blackmail that is discussed in
more detail in Chapter 6.
Reduced Operational Babyminding Control
Cloud consumers are usually allotted a akin of babyminding ascendancy that is
lower than that over on-premise IT resources. This can acquaint risks
associated with how the billow provider operates its cloud, as able-bodied as the
external access that are appropriate for advice amid the
cloud and the billow consumer.
Consider the afterward examples:
• An capricious billow provider may not advance the guarantees it makes
in the SLAs that were appear for its billow services. This can
jeopardize the affection of the billow customer solutions that await on these
• Longer geographic distances amid the billow customer and cloud
provider can crave added arrangement hops that acquaint fluctuating
latency and abeyant bandwidth constraints.
The closing book is illustrated in Figure 3.10.
Figure 3.10. An capricious arrangement affiliation compromises the affection of
communication amid billow customer and billow provider environments.
Legal contracts, back accumulated with SLAs, technology inspections, and
monitoring, can abate babyminding risks and issues. A cloud
governance arrangement is accustomed through SLAs, accustomed the “as-a-service”
nature of billow computing. A billow customer charge accumulate clue of the
actual account akin actuality offered and the alternative warranties that are made
by the billow provider.
Note that altered billow commitment models action capricious degrees of
operational ascendancy accepted to billow consumers, as added explained
in Chapter 4.
Limited Portability Amid Billow Providers
Due to a abridgement of accustomed industry standards aural the cloud
computing industry, accessible clouds are frequently proprietary to various
extents. For billow consumers that accept custom-built solutions with
dependencies on these proprietary environments, it can be challenging
to move from one billow provider to another.
Portability is a admeasurement acclimated to actuate the appulse of affective cloud
consumer IT assets and abstracts amid clouds (Figure 3.11).
Figure 3.11. A billow consumer’s appliance has a decreased akin of portability when
assessing a abeyant clearing from Billow A to Billow B, because the billow provider of
Cloud B does not abutment the aforementioned aegis technologies as Billow A.
Multi-Regional Acquiescence and Acknowledged Issues
Third-party billow providers will frequently authorize abstracts centers in
affordable or acceptable bounded locations. Billow consumers will
often not be acquainted of the concrete area of their IT assets and data
when hosted by accessible clouds. For some organizations, this can pose
serious acknowledged apropos pertaining to industry or government regulations
that specify abstracts aloofness and accumulator policies. For example, some UK
laws crave claimed abstracts acceptance to UK citizens to be kept aural the
Another abeyant acknowledged affair pertains to the accessibility and disclosure
of data. Countries accept laws that crave some types of abstracts to be
disclosed to assertive government agencies or to the accountable of the data.
For example, a European billow consumer’s abstracts that is amid in the
U.S. can be added calmly accessed by government agencies (due to the U.S.
Patriot Act) back compared to abstracts amid in abounding European Union
Most authoritative frameworks admit that billow consumer
organizations are ultimately amenable for the security, integrity, and
storage of their own data, alike back it is captivated by an alien cloud
Summary of Key Points
• Billow environments can acquaint audible aegis challenges, some of which
pertain to overlapping assurance boundaries imposed by a billow provider administration IT
resources with assorted billow consumers.
• A billow consumer’s operational babyminding can be bound aural cloud
environments due to the ascendancy acclimatized by a billow provider over its platforms.
• The portability of cloud-based IT assets can be inhibited by dependencies
upon proprietary characteristics imposed by a cloud.
• The bounded area of abstracts and IT assets can be out of a cloud
consumer’s ascendancy back hosted by a third-party billow provider. This can
introduce assorted acknowledged and authoritative acquiescence concerns.
