IT
Perspective for Developer


Capital Expenditure (
CapEx
) for development environ.
could be high


Acquisition of hardware, software, necessary services, etc.


HW, SW upgrades, back up/restore of development
environ., etc.


Operational Expenditure (
OpEx
) for support, etc.


Development environ. utilization low


IT
Perspective for DC


CapEx

for the data center (DC) is very high


Scalability, availability, and DR require redundant HW + SW


OpEx

can also be high


App administrators, DBA, storage administrators are
expensive


Data center power usage and cooling has also become a big
issue


Data center resource utilization is typically low


Redundant HW + SW usually sit idle for a long time


Enterprise Perspective

ISP evolution

What’s cloud computing?

Service (
IaaS
)


Consumer uses provider’s processing, storage, networks,
and other fundamental computing resources to deploy
and run arbitrary software, which can include operating
systems and applications.

Elastic Compute Cloud (EC2)

Cloud Computing Deployment
Models


Private cloud.
The cloud infrastructure is operated solely for an
organization. It may be managed by the organization or a third
party and may exist on premise or off premise.


Community cloud.

The cloud infrastructure is shared by several
organizations and supports a specific community that has shared
concerns.


Public cloud.
The cloud infrastructure is made available to the
general public or a large industry group and is owned by an
organization selling cloud services.


Hybrid cloud
. The cloud infrastructure is a composition of two or
more clouds that remain unique entities but are bound together
by standardized or proprietary technology that enables data and
application portability.
