Some real examples…
Pizzas from the Cloud…• Availability is a critical requirement• Spikes in demand• Optimize computing capacity while
being able to handle peak demand
SOLUTION:
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:
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:
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:
Different types of services…
Challenges in Cloud Computing…
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. COURTESY: http://acet.rdg.ac.uk/~mab/Talks/Clouds-La-Coruna09/Talk.ppt
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

Getting started in Cloud Computing..
Getting started in Cloud Computing…
1. Know the different options available to you2. Understand that scaling is a skill, not a default3. Implement a disaster plan4. Don’t be naïve5. Budget for your specific use-case6. Choose a cloud provider on your needs, not its popularity7. Remember: some applications are not good fits for cloud8. Think outside of the box

Future of Cloud Computing…
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.
