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…

Three major kinds of Cloud 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.
