  3. 3. Cloud Computing CLOUD + COMPUTING Computing done over the Internet !
  4. 4. Cloud Computing Conventional Computing CONVENTIONAL COMPUTING ? o Where all the work are done locally and on the desktop o Hardware and software sits on the office workplace o Processing work are done individually
  5. 5. Cloud Computing Conventional Computing CLOUD COMPUTING ? o Actual computing work are done on the ‘cloud’ o Distributed across the network, to several computers o Which may be operated by service provider
  6. 6. Cloud Computing Conventional Computing (Individual Processing) Cloud Computing (Massive Processing) 2 x 2.4 GHz CPU 8 GB RAM ANALYZING 240 TB DATA 2 x 2.4 GHz CPU 8 GB RAM 2 x 2.4 GHz CPU 8 GB RAM 2 x 2.4 GHz CPU 8 GB RAM 16 CPU, 64 GB RAM
  7. 7. Cloud Computing “The whole is more than sum of its parts”
  8. 8. Cloud Computing Users Gmail Service Features o Offers 15 GB storage Space o 2,000 – 3,000 sign-ups per day o 5000 TB data transfer per day Compare o If UiTM Perlis has 8,000 users o 15 GB x 8,000 o 120,000 GB data o Where can you get hard disk that massive?
  9. 9. Cloud Computing Users
  10. 10. Cloud Computing as a Service o Cloud Computing involves delivering hosted services over the internet o These services are broadly divided into THREE(3) categories: o Infrastructure-as-a-Service (IaaS) o Platform-as-a-Service (PaaS) o Software-as-a-Service (SaaS)
  11. 11. Why all these are offered “as-a-service” ?? “Why do we need to hire/rent/lease these hosted cloud services?” “We could better run our own cloud infrastructure ourselves?”
  12. 12. Why we need to rent/lease Cloud Service ? o Imagine we’re running a business office o The office may require overhead / maintenance o Washroom/Toilet Cleaning o Electrical works (what if air-conditioning does not work?) o Security / Safeguards o We can either maintain these ourselves or, we can hire specialist in the field o Advantage: We could concentrate on expanding our Business
  13. 13. Why we need to rent/lease Cloud Service ? o The same concept also applies on renting/leasing Cloud Computing Service o Instead of spending time maintaining, upgrading hardware & software which may cost TIME and MONEY, o We can concentrate our time on offering better products to our stakeholders o Let the specialist handle the infrastructure
  14. 14. IaaS, PaaS & SaaS ? Three general type of Cloud Computing o Infrastructure-as-a-Service (IaaS) o Platform-as-a-Service (PaaS) o Software-as-a-Service (SaaS
  15. 15. Infrastructure as a Service (IaaS) Infrastructure as a Service (IaaS) is a form of cloud computing that provides virtualized computing resources over the Internet oCPU / Processing time oMemory / RAM oStorage
  16. 16. Platform-as-a-Service (PaaS) o PaaS is a cloud model in which providers deliver apps over the Internet and host users' hardware and software on their infrastructure o Sits between SaaS and IaaS o Sometimes called “Container” o Windows Azure o OpenStack o Docker o Google App Engine
  17. 17. Software-as-a-Service (SaaS) o Software as a Service provides network-based access to networked-based software o If you use the internet, you might already use one of these SaaS o Google Docs o I-Learn / Moodle / Padlet o Shazaam o Salesforce o Microsoft Office 360 o Wolfram-Alpha
  18. 18. Relationship between IaaS, PaaS and SaaS
  19. 19. Relationship between IaaS, PaaS and SaaS
  20. 20. Cloud Computing is not… oMerely a buzzword o Act of storing files on the remote computer oMerely a one-to-many client-server network
  21. 21. Cloud Computing Advantages o Provides Business Process Abstraction o Simplifies Maintenance o Separates Roles o Provides Redundancy o Offer better protection from DDoS / Attacks
