Cloud computing, with the revolutionary promise o computingas a utility, has the potential to transorm how IT services aredelivered and managed. Yet, despite its great promise, even themost seasoned proessionals know little about cloud computingor how to defne it. A recent study revealed that 41% o senior ITproessionals admit that they “don’t know” what cloud comput-ing is. This research ollows a similar survey highlighting thattwo-thirds o senior fnance proessionals are conused aboutcloud computing (Version One, 2009).

Executive Summary


“The Federal Government will

transform its IT infrastructure by

virtualizing data centers, consoli-

dating data centers and operations,

and ultimately adopting a cloud

computing business model.”

Defning Cloud Computing

ational nstitut of Standards and

cnology’s (S) nformation cnology 

aboratory rcognizs tat cloud computing

is an “volving paradigm.” s suc, its

dnition, attributs, and caractristics

ar still bing dbatd by t public and

privat sctors, and ar crtain to continu

to volv in t nar futur. vrtlss,

initial stps av bn takn toward con-

structing a univrsally accptd xplanation

of cloud computing’s ky caractristics,

as wll as dnitions for t various

dploymnt and srvic modls. s

dnitions av bn widly rportd but

ar wort rpating, particularly in a ld

tat is still rapidly dvloping.

According to NIST:

Cloud computing is a modl for nabling

convnint, on-dmand ntwork accss

to a sard pool of congurabl computing

rsourcs (.g., ntworks, srvrs, storag,applications, and srvics) tat can b

rapidly provisiond and rlasd wit

minimal managmnt ffort or srvic

providr intraction.

is cloud modl promots availability 

and is composd of v ssntial carac-

tristics, tr srvic modls, and four

dploymnt modls.

The Five Essential Characteristics

On-demand Self Service. consumr can

unilatrally provision computing capabili-

tis, suc as srvr tim and ntwork

storag, as ndd automatically witout

rquiring uman intraction wit ac

srvic’s providr.

Broad Network Access. Capabilitis ar

availabl ovr t ntwork and accssd

troug standard mcanisms tat

promot us by trognous tin

or tick clint platforms (.g., mobil

pons, laptops, and PDs).

Resource Pooling. providr’s comput-

ing rsourcs ar poold to srv multipl

consumrs using a multi-tnant modl

wit diffrnt pysical and virtual rsourcs

dynamically assignd and rassignd

according to consumr dmand. r is

a sns of location indpndnc in tat

t customr gnrally as no control

or knowldg ovr t xact location of 

t providd rsourcs but may b abl

to spcify location at a igr lvl of 

abstraction (.g., country, stat, or data

cntr). exampls of rsourcs includ

storag, procssing, mmory, ntwork

bandwidt, and virtual macins.

Rapid Elasticity. Capabilitis can b rapidly 

and lastically provisiond, in som

cass automatically, to quickly scal out,

and rapidly rlasd to quickly scal in.o t consumr, t capabilitis avail-

abl for provisioning oftn appar to b

unlimitd and can b purcasd in any 

quantity at any tim.

Measured Service. Cloud systms auto-

matically control and optimiz rsourc

us by lvraging a mtring capability 

at som lvl of abstraction appropriat

to t typ of srvic (.g., storag,

procssing, bandwidt, and activ usr

accounts). sourc usag can b moni-tord, controlld, and rportd providing

transparncy for bot t providr and

The Four Deployment Models

Private Cloud. cloud infrastructur

is opratd solly for an organization. t

may b managd by t organization or

a tird party and may xist on prmis

or off prmis.

Community Cloud. cloud infrastruc-

tur is sard by svral organizations

and supports a spcic community tat

as sard concrns (.g., mission,

scurity rquirmnts, policy, and compli-

anc considrations). t may b managd

by t organizations or a tird party and

may xist on prmis or off prmis.

Public Cloud. cloud infrastructur is

mad availabl to t gnral public or a

larg industry group and is ownd by an

organization slling cloud srvics.

Hybrid Cloud. cloud infrastructur

is a composition of two or mor clouds

(privat, community, or public) tat

rmain uniqu ntitis but ar bound

togtr by standardizd or propritary 

tcnology tat nabls data and appli-

cation portability (.g., cloud bursting for

load-balancing btwn clouds).

The Benefts o Cloud Computing

Cloud Computing Maturity Model

rcommnds a pasd approac to

Step 1: Consolidation

and incras quipmnt usag, all

troug t masurd planning of bot

Consolidation is acivd primarily 

troug virtualization but can also b

approacd by t us of dnsr

formanc computing. By boosting t

spd of critical procsss and nabling

gratr xibility, t consolidation of 

data cntrs and dsktops allows agn

a signicant concrn in today’s conom

nvironmnt. Morovr, t sift to a

unid fabric provids bot pysical and

virtual accss to t storag ara ntwor
