7. Cloud
Computing
–
Many
Definitions
* On-­‐demand
self-­‐service
internet
infrastructure
where
you
pay
as
you
go
and
use
only
what
you
need,
all
managed
by
a
browser,
application
or
API
* Clouds
will
be
the
next
transformation
over
the
next
several
years,
building
off
of
the
software
models
that
virtualization
enabled
* +
100s

experts,
vendors
and

8. NIST
Definition
of
Cloud
Computing
Cloud
computing
is
a
model
for
enabling
convenient,
on-­‐demand
network
access
to
a
shared
pool
of
configurable
computing
resources
(e.g.,
networks,
servers,
storage,
applications,
and
services)
that
can
be
rapidly
provisioned
and
released
with
minimal
management
effort
or
service
provider
interaction.

Predictions
1) The
industry
is
poised
for
strong
growth
through
2014,
when
worldwide
cloud
services
revenue
is
projected
to
reach
$148.8
billion

2) Public
IT
cloud
will
be
over
25%
of
the
net-­‐new
growth
in
traditional
IT
products
between
now
and
2014
–

3) The
global
market
for
enterprise
cloud-­‐based
services
will
grow
from
$12.1
billion
in
2010
to
$35.6
billion
in
2015

billion
in
2009,
predicting
a
market
size
of
$100.4

23. Is
Cloud
A
Cure
For
IT
Headaches?
Yes
But
some
people
seem
to
have
security
&
privacy
concerns

24. Cloud
Is
Not
Secure?

25. Security
&
Privacy
Concerns
* Cloud
Provider’s
Security
Practices
* Regulatory
Needs
* Data
Ownership
* Data
Privacy

26. Mental
Shift
Losing
Control
Trust

27. In
Reality
* Cloud
is
neither
more
nor
less
secure
than
the
traditional
IT.
But
in
the
case
of
most
SMBs,
Cloud
provides
better
security
* With
the
loss
of
control,
different
kind
of
risks
comes
into
focus
* Industry
best
practices
can
help
mitigate
these
risks.

Cloud
Security
Alliance
(CSA)
* Bottom
Line
is
balancing
the
risks
to
take
advantage
of
the
clouds

28. Vendor
Responsibility

29. Conclusion
* Cloud
is
real
and
maturing
fast.
Businesses
of
all
sizes
and
shapes
are
going
to
adopt
it
much
sooner
than
many
expect
* Using
Cloud
Computing
becomes
a
competitive
advantage
* A
big
part
of
the
security
concerns
are
due
to
FUD
but
it
is
also
critical
to
understand
the
risks
and
take
steps
to
mitigate
them,
to
take
the
full
advantage
of
clouds
* Leverage
the
cloud
but
control
your
destiny
