• Conclusion

4. What is Cloud Computing?

5. Traditional Model Cloud Computing Model
Proprietary internal IT resources Remote, shared services
Company A Company B
Internet
Company A Company B

6. What constitutes Cloud Computing?

7. Utility Pricing
“Utility Pricing” • Pay-as-you-go
• Pay-as-you-grow
• Low up-front investment
• Purchase resources on-the-
fly

8. Auto-elasticity
“Auto-elasticity”
“Utility Pricing” • On-demand resource
configuration
• Massively scalable
• Scale up or down

9. Virtualization
“Auto-elasticity”
“Utility Pricing” • Abstraction of execution
environment
“Virtualization” • Resource quota
• Reduced number of physical
machines

10. Management
Automation
“Auto-elasticity”
“Utility Pricing” • One-click provisioning
“Management • Policy based resource
“Virtualization” Automation” allocation
• Automated backups
• Real-time disaster recovery

11. Third-party
ownership
“Auto-elasticity”
“Utility Pricing” • Focus on core-business
“Management • Leave rest to someone else
“Virtualization” Automation” • Don’t worry about system
maintenance etc…
“Third-party
ownership”

12. Some examples that uses Cloud…

13. IEEE GOLD Singapore
• Interest group
• Members work in different places
• They need to share different
documents
• They need to maintain a GOLD email in
conjunction with their company email
SOLUTION:

14. Pizzas from the Cloud…
• Availability is a critical requirement
• Spikes in demand
• Optimize computing capacity while
being able to handle peak demand
SOLUTION:

15. Brewing customer feedback
• Build an online community to engage with
customers and employees dynamically
• Required community management tools to
track and implement the best ideas
SOLUTION:

16. Real-estate in Cloud
• Procuring and installing
servers or upgrades are
distraction
• Difficult to anticipate
hardware demand
• Unanticipated hardware
failures leads to terrible
impact on productivity
SOLUTION:

17. Location-based commerce
• View map of your
location, and surrounding
businesses & services
• Discover what's new,
what's on sale, at which
stores around you
• Locate nearest bus stops,
MRT stations, taxi stands;
access real-time
estimates of next bus
arrival times
SOLUTION:

18. Different types of services…

19. Three kinds of services
SaaS • Software as a Service (SaaS)
• Platform as a Service (PaaS)
• Infrastructure as a Service (IaaS)
PaaS
IaaS

20. SaaS
• An application is hosted as a
SaaS service provided to customers
across the network
• E.g. Google Apps, Web-based
PaaS email, facebook applications
IaaS

21. PaaS
SaaS • Deploy customer created
applications to a Cloud
• E.g. Facebook platform, Google
PaaS App-engine
IaaS

22. IaaS
SaaS • Rent resources such as CPU,
storage and network capacity
• Customer has control over the
PaaS OS, storage and applications
• E.g. Amazon Web Services
IaaS

32. Challenges in Cloud Computing…

33. • Requires a constant Internet connection:
– No internet means no access to even your own documents
• Features might be limited:
– This situation is bound to change
– For example, you can do a lot more with Microsoft PowerPoint
than with Google Presentation's web-based offering.
– The basics are similar, but the cloud application lacks many of
PowerPoint's advanced features.

34. • Stored data might not be secure:
– How secure is the cloud?
– Can unauthorized users gain access to your confidential data?
– Only time will tell if your data is secure in the cloud.
• Stored data can be lost:
– Theoretically, data stored in the cloud is safe, replicated across
multiple machines.
– But data loss can happen

35. Getting started in Cloud Computing..

36. 1. Know the different options available to you
2. Understand that scaling is a skill, not a default
3. Implement a disaster plan
4. Don’t be naïve
5. Budget for your specific use-case
6. Choose a cloud provider on your needs, not its popularity
7. Remember: some applications are not good fits for cloud
8. Think outside of the box

40. Numbers!!!
• By 2011 cloud computing market will reach $160 billion.
• The number of physical servers in the World today: 50 million.
• By 2013, approximately 60% of server workloads will be virtualized
• 50% of the 8 million servers sold every year end up in data centers
• The data centers of the dot-com era consumed 1-2 MW Today data
center facilities require 20 MW, - 10 times as much as a decade ago
• Google currently controls 2% of all servers ( around 1 million) with it
saying it plans to have upwards of 10 million servers in one decade
• 98% of the market is controlled by everyone else.
