2. What is Cloud Computing?
• “A style of computing where scalable and
elastic IT-related capabilities are provided ‘as
a service’ to customers using Internet
Technologies” .
PROF. ERWIN M. GLOBIO, MSIT

3. The Needs
• Users needs Application Software (such as
office applications)
• Business needs Infrastructure (Software for
enterprise business operation and Hardware
for network and storage)
• Developers needs Platform (such as ROR
working on a server environment)
PROF. ERWIN M. GLOBIO, MSIT

4. Software, Platform, and Infrastructure
in companies
PROF. ERWIN M. GLOBIO, MSIT

5. Current Set-Up
• Users installs the software in the PC.(Cost of
buying licensed software)
• Business invest hardware, software and
infrastructure to automate their business
process and store transactional data. (Capital
Expenditure on server farm, storage and
firewall)
• Application Developer Companies invests on
platform for application development.
PROF. ERWIN M. GLOBIO, MSIT

6. Disadvantage of the Current Set Up
• Cost of Acquisition
• Cost of Installation, Set up and training
• Cost of Maintenance
• Cost of Scaling Hardware
• Cost of Disposal
PROF. ERWIN M. GLOBIO, MSIT

7. The Green Solution
• Cloud Computing both answers the computing
needs of the users, business, and developers
and counteracts the disadvantages of the
current set up.
• It is where software applications, data storage,
and processing capacity are accessed over the
internet.
PROF. ERWIN M. GLOBIO, MSIT

8. Software, Platform, and Infrastructure
placed in the Cloud
PROF. ERWIN M. GLOBIO, MSIT

9. PROF. ERWIN M. GLOBIO, MSIT

10. Cloud Computing Explained
• Allow users to run applications and store data
online.
• Each offers a different level of user flexibility
and control
PROF. ERWIN M. GLOBIO, MSIT

11. SAAS – Software As A Service
• Allow users to run online applications
PROF. ERWIN M. GLOBIO, MSIT

12. PAAS – Platform As A Service
• Allows users to create their own cloud
applications using supplier – specific tools and
languages
PROF. ERWIN M. GLOBIO, MSIT

13. IAAS – Infrastructure As A Service
• Allows users to run any applications as they
please on cloud hardware of their own choice
PROF. ERWIN M. GLOBIO, MSIT

14. Three ways to cloud compute
• SAAS – Software As A Service
• IAAS – Infrastructure As A Service
• PAAS – Platform As A Service
PROF. ERWIN M. GLOBIO, MSIT

15. Software As A Service
• Is the easiest way to cloud compute
• Where off-the shelf applications are accessed
over the Internet
PROF. ERWIN M. GLOBIO, MSIT

16. Example of SAAS - Microsoft Office
Web Apps
PROF. ERWIN M. GLOBIO, MSIT

17. Example of SAAS – Microsoft Office
Web Apps

18. Example of SAAS – Image Editor
PROF. ERWIN M. GLOBIO, MSIT

19. Example of SAAS – Video Editing
PROF. ERWIN M. GLOBIO, MSIT

20. Example of SAAS – Creative Suite
PROF. ERWIN M. GLOBIO, MSIT

21. Example of SAAS – Employee
Information Management
PROF. ERWIN M. GLOBIO, MSIT

22. Example of SAAS – Business Process
Suite
PROF. ERWIN M. GLOBIO, MSIT

23. Example of SAAS – CRM Solution
PROF. ERWIN M. GLOBIO, MSIT

24. SAAS Pros and Cons
• Free or via paid subscription
• Accessible to any computer or internet
enabled mobile device
• Facilitates collaborative working
• Generic applications not always suitable for
business use
PROF. ERWIN M. GLOBIO, MSIT

25. PAAS – Platform As A Service
• Provides environment and tools for creating
for creating new online applications
PROF. ERWIN M. GLOBIO, MSIT

26. Example of PAAS

28. Example of PAAS
PROF. ERWIN M. GLOBIO, MSIT

29. PAAS Pros and Cons
• Rapid development at low cost
• Private or Public Deployment
• Limits developers to provider languages and
tools
• Risk of Vendor Lock - in
PROF. ERWIN M. GLOBIO, MSIT

30. Advantage of Cloud Computing
• Economies of Scale – underutilization and
misappropriated hardware become a thing of
the past. The cloud enables compute, storage
and RAM resources to be more efficiently
managed, provisioned and scaled, all within a
shared environment.
PROF. ERWIN M. GLOBIO, MSIT

31. Advantage of Cloud Computing
• Cost Control – knowing exactly what you are
using and how much that usage will cost you
allows for a much stricter control over
expenditures.
• “Disposable IT” – companies have the ability
to create, use and destroy infrastructure
based on their business needs.
PROF. ERWIN M. GLOBIO, MSIT

32. Advantage of Cloud Computing
• Burstable Workloads– scaling based on
demand allows organizations to efficiently use
infrastructure in a timely basis.
• Avoiding Capital Expenditure – with cloud
computing, infrastructure becomes an
operating expense with no need to amortize
hardware costs over time.
PROF. ERWIN M. GLOBIO, MSIT

33. Types of Cloud Deployment
Infrastructure
• Private (single tenant environment)
– Hosted and on premises(in house)
• Public (shared environment)
• Hybrid (combination)
PROF. ERWIN M. GLOBIO, MSIT

34. In Summary how will you know if it is
cloud computing
• If its offered as a Service whether software,
Infrastructure or Platform its cloud computing.
Think of it as if you are renting the use of the
software, infrastructure and platform.
