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 withcustomers and employees dynamically

Required community management tools totrack and implement the best ideas

Real-estate in Cloud Procuring and installing

servers or upgrades aredistraction

Difficult to anticipatehardware demand

Unanticipated hardwarefailures leads to terribleimpact on productivity

SOLUTION:

Location-based commerce View map of your

location, and surroundingbusinesses & services

Discover what's new,what's on sale, at whichstores around you

Locate nearest bus stops,MRT stations, taxi stands;

access real-timeestimates of next busarrival times

Different types of services


19/41

Three kinds of services

Software as a Service (SaaS)

Platform as a Service (PaaS)

Infrastructure as a Service (IaaS)

SaaS

SaaS An application is hosted as a

service provided to customers

across the network

E.g. Google Apps, Web-basedemail, facebook applications

Challenges in Cloud Computing

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 acrossmultiple machines.

But data loss can happen

Getting started in Cloud Computing..


36/41

1. Know the different options available to you

2. Understand that scaling is a skill, not a default

3. Implement a disaster plan4. Dont be nave

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 cloud8. Think outside of the box

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 itsaying it plans to have upwards of10 million servers in one decade

98% of the market is controlled by everyone else.
