8. Google Trends
Cloud computing, Grid computing, Cluster computing

9. Some real examples…

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

11. 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:

12. 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:

13. 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:

14. Different types of services…

15. Three major kinds of Cloud services

16. Challenges in Cloud Computing…

17. Challenges…
• 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.

18. Challenges…
• 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

19. Getting started in Cloud Computing..

20. Getting started in Cloud Computing…
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

22. Future of Cloud Computing…

23. 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.
