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).

“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

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

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

rapidly provisiond and rlasd wit

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

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

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

The Four Deployment Models

Private Cloud. cloud infrastructur

is opratd solly for an organization. t

a tird party and may xist on prmis

or off prmis.

Community Cloud. cloud infrastruc-

tur is sard by svral organizations

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

stablismnt of a cloud computing

maturity modl (CCMM) provids a fram-

work for succssful implmntation. GS

rcommnds a pasd approac to

t CCMM, ncompassing v ky 

componnts:

• Consolidation

• Virtualization

• utomation

• tility 

• Cloud

Step 1: Consolidation

tion of srvr, storag, and ntwork

rsourcs, wic works to rduc

rdundancy, dcras wastd spac,

and incras quipmnt usag, all

troug t masurd planning of bot

arcitctur and procss.

Consolidation is acivd primarily 

troug virtualization but can also b

approacd by t us of dnsr

computing ardwar or vn ig pr-

formanc computing. By boosting t

spd of critical procsss and nabling

gratr xibility, t consolidation of 

data cntrs and dsktops allows agn

cis to do mor wit fwr rsourcs –

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

(S), crating gratr fcincy and

cost savings by allowing mor storag

to b consolidatd in t S.

twork and application modrniza-

tion is also an important initial stp

in nabling t transition to a cloud

computing nvironmnt. viabl

altrnativ to rplacing infrastructur

componnts or rwriting critical applica

tions, modrnization promots com-munication btwn oldr systms and

tions. Wn stablisd proprly, t

cloud platform provids scurity of all

virtualization allows gratr fcincy

By sparating t workload from t

– it nabls t mobility of applications

and data, not only across srvrs and

storag arrays, but also across data

cntrs and ntworks. Morovr, troug

can rgain control of tir distributd

rsourcs by crating sard pools of 

standardizd rsourcs tat nabl

t ultimat goal in cloud computing is t

us of t abstraction btwn applica-

Conclusion

Wit its convnint, on-dmand modl

for ntwork accss to a sard pool

of congurabl computing rsourcs,

cloud computing is rapidly mrging

as a viabl altrnativ to traditional

approacs – and is carrying a ost of 

provn bnts to govrnmnt agncis.

Costs ar bing signicantly rducd,

along wit prsonnl tim spnt on

computing issus. Storag availability incrass, ig automation liminats

worris about kping applications up

to dat, and xibility and mobility ar

igtnd, allowing workrs to accss

information anytim, anywr.

Cloud computing can b rapidly provisiond

and rlasd wit minimal managmnt

ffort or srvic providr intraction.

ltimatly, wit its offring of scalabl,

ral-tim, intrnt-basd information

of a univrs of usrs, witout t usrs

incurring t costs of maintaining t
