•Deploy testin & Improvemeit
•Moiitor, Minrate & Audit

5. Cloud maianemeit lifecycle

6. Cloud Maianemeit lifecycle
•Plaiiiin- creatin a iew cloud set-up with iew
hardware & sofware
•Set-up-adopts to IaaS, PaaS, & DBaaS
•Buildiin- packiin & publishiin of applicatois

•Moiitoriin & Maianiin- moiitors the setin,
staidards policies & ornaiize
•Meteriin, Charniin & Optmizatoi-usane of
resources as CPU, storane & memory

7. ROLE OF CLOUD MODELLING &

8. REFERENCE MODEL FOR CLOUD
COMPUTING
•Ref. Architecure provides the bluepriit aid/or
architecture reused by others
•Refereice model- explaiis what the refereice
architecture comprises aid its relatoiships.

9. Cloud Architecture
•Cloud Computin Lonical Architecture
•Developiin Holistc Cloud Computin
Refereice Model
•Cloud System Architecture
•Cloud Deploymeit Model

10. CLOUD COMPUTING LOGICAL ARCHITECTURE
•Cloud Computin Architecture
– Ai iiteriet based techiiques usiin shared resources available.cc is a
type of eiviroimeit, where IT busiiesses outsource their computin
ieeds, which iiclude s/w applicatoi services to veidors(i.e storane,
database, e-mails etc., accessed via WWW)
–Cc divided iito 2 parts: froit eid (customer’s devices-computer) &
back eid(ietwork &applicatois for accessiin).
•Examples of Cloud Computin
–Gmail & yahoo (seidiin e mails)
•Cloud computin types
–Public, private & hybrid
•Need of cloud computin
–Maii purpose to save coisumer’s iifrastructure & maiiteiaice cost.

11. Cc lonical arch coitiued
•Problems with CC
–Major coiceris are security & privacy
•cloud computin service architecture
–3 types of services available with cloud service provider
–IaaS, PaaS & SaaS
•Uiderstaidiin cloud computin architecture models
–Major challeine: io defied staidard or architecture
–Cl. Arch : cai be viewed as a collectoi of difereit fuictoialites aid
capabilites.
–cloud computin models
•CC model coisists of a collectoi of servers , which are virtualized usiin a tool.
•Siinle pool haviin maiy servers
•E.n PaaS- salesforce.com

12. DEVELOPING HOLISTIC CLOUD COMPUTING REFERENCE MODEL
–cloud refers to combiied set of h/w ,storane ,i/w, services & iiterfaces.
–coisumer cloud services are widely used ii the iiteriet.
•1.Cloud computin: takiin a complete view(makes efcieit use of
resources)
• 2.Complete view of cloud maianemeit
–5 top level research areas for aialysiin obstacles
•Optmizatoi ii deploymeit aid coistructoi of cloud services.
•Self-preservatoi ii resource maianemeit.
•Self-maianemeit for various cloud services & decisioi makiin
•Support for service deploymeit.
•Market aid lenislatve issues.

13. ---coitiued--
–Cloud deploymeit model
•CDM &CEM(CLOUD ECO SYSTEM) Determiies
security, architectural & maianemeit challeines.
–Cloud noveriaice & operatois model(helps ii
makiin choices ii cloud eiablemeit
approaches)
–Cloud ecosystem model-It is the physical, lonical
& virtual eiviroimeit (providers, lonical &
virtual eiviroimeit)

14. CLOUD SYSTEM ARCHITECTURE
•Factors to be coisidered while desiniiin cloud
based architecture
–Cost
–Complexity
–Speed
–Cloud portability
–Security

15. CLOUD SYSTEM ARCHITECTURE
•Example refereice dianram
Siinle cloud site architectures
•Ii this load balaicer, applicatoi lonic, databases& storane are
located ii the cloud. Oily testin the iiteractvity betweei the
ters.
–Reduidait 3-ter architecture
•Usiin of a striped volume set ii reduidait 3-ter architecture at
the database. It is hune & ieed faster backups for data storane.
–Mult data ceitre architecture
•Multple data ceiters'- haviin a load balaiciin applicatoi,
volume & master database. Whei oie data ceitre noes dowi ,
the other cai used automatcally.

16. CLOUD DEPLOYMENT MODEL
•Cloud computin deploymeit model
–Private cloud- iot shared with other ornaiizatoi
–Public cloud- web services over the iiteriet
–Hybrid cloud- combiiatoi of private, public &commuiity
–Commuiity cloud- supports a partcular commuiity
–Combiied cloud- combiiiin iiterial &exterial providers
–Iiter cloud (cloud of cloud)-mesh of cloud, iitercoiiected usiin opei
staidards to provide a uiiversal acceptaice.
•Types of cloud deploymeit model(all ecoiomic beiefts)
–Private cloud
–Public cloud
–Hybrid cloud

17. Cloud Modeliin Aid Desini
•Cloud Computin: Basic Priiciples
–Key priiciples & examples of cloud eiviroimeit
•Model For Federated Cloud Computin
–Cloud federatoi
–Two layer coiiectvity for cloud federatoi
•Cloud Ecosystem Model
–Cloud ecosystem
–Cloud broker/cloud aneit
–Cloud outlook
–Cloud uiifed process
•Cloud Goveriaice
–Takiin steps to clarify cloud Goveriaice
–SOA & cloud noveriaice
–CG: desini tme, rui tme
–Stanes of a service lifecycle
–Successful cloud noveriaice & adoptoi

18. CC BASIC PRINCIPLES
•BENEFITS –improve novt. services, citzei
access, traisform busiiesses, provide
iiiovatois , eierny saviin.
•Factors for promotin-ieed assuraice renard
security, illenal actvites(thef, hackiin),Data
portability

19. --key priiciples
•Abstractoi- A well-defied abstractoi layer acts as nrease b/w
cloud & developers(user).
–applicatoi as a service, PaaS & Iaas
•Automatoi- load balaicer iitmates the cloud as extra ios. be
provided. This reduces cost & complexity.
•Elastcity- people cai easily scale up aid dowi accordiin to daily
usane.
•Example- IBM power systems
–workload optmizatoi
–Limitless virtualizatoi
–Automated maianemeit
–Solutois of all kiids.

20. Model for federated CC
•Cloud federatoi: iitercoiiectin the CC
eiviroimeit with 2 or more service providers for
balaiciin the trafc load.
•Federatoi: difereit cloud favors are
iitercoiiected. Acts as a bridne b/w two cloud
eiviroimeit.
•Two layer coiiectvity: hybrid clouds are achieviin
almost worldwide publicity. Hybrid model
iitercoiiects iiterial & exterial resources.

21. Cloud eco system
•Defies the complexity of the systems ii terms
of its iiterdepeideit compoieits that work
tonether to eiable cloud services.
•Cloud broker/cloud aneit:
– is a third party persoi, acts as ai ofcer b/w
customer & seller.
–Is a s/w applicatoi , facilitates shariin of work
b/w various cloud service providers.

22. --coitiued—
•Cloud outlook
–Bin data –larne volume of data
–Busiiess- iot like IaaS, PaaS
& BPaaS. It is more thai that.
-mobile-empower the users aid
Iicrease coisumerizatoi aiy body,
Aiywhere, aiytme & aiy device.
-namifcatoi- will make techiolony edutaiimeit
Guide a partcipait with a path to mastery
Aid autoiomy, eicourane users to iivolve ii desired
Behaviors.

24. CLOUD UNIFIED PROCESS
•Ai eid-to-eid iiteractve aid iicremeital process structure for
the developmeit aid operatois of cloud services ii a lifecycle
fashioi is called CUP.
•CUP framework –hierarchical structure.
–Top-level 5 compoieits
–1
st level-Stratenize, traisform, operatoialize, rui & eirich(store)
–2
id level –iiput, output & actvites
•To develop a uiifed road mappiin structure 4 iicremeital stanes
are ieeded: plai, adopt, traisform & hariess(path). The best
road mappiin practces execute PATH are: alinimeit ,bluepriit,
checklist & alinimeit.
