Cloud

of

Technology
(NIST)
as
“
a
model
for
enabling
ubiquitous,
convenient,
on-­‐demand
network
access
to
a
shared
pool
of
configurable
compu2ng
resources
(e.g.,
networks,

that
can
be
rapidly
provisioned
and

with

What
changes
when
an
applica2on
moves
to
Cloud
• Cloud
environment
is
extremely
complex.
Large
afack

owing
to
many
components
in
the
cloud
• Shared
mul2-­‐tenant
environment
–
Infra

shared
with
unknown

• Auto
Scaling
will
provision
more
resources
to
handle
increased

The
result
is
high
performance,
regardless
of
the
user
demand.
• Auto

What
changes
when
an
applica2on
moves
to
Cloud
• ASP
Model
typically
involved
delivering
applica2on
services
using
separate
single
tenant
or
client
instances
• Cloud
uses
resource
pooling,
to
serve
mul2ple
customers
using
a
mul2-­‐tenant
model,
with
different
physical
and
virtual
resources
dynamically
assigned
and
reassigned
according
to
customer
demand.
