Before the Web
� If you wanted to sell things to the public, you needed a storefront
� Massive cost in real estate, fixtures, maintenance,
shrinkage
� Prohibitive cost to entry
4 An Introduction to Cloud Computing © 2009 IBM Corporation
Presented by IBM developerWorks
What if …
� You could have hundreds of millions of storefronts worldwide?
�Without real estate
�Without fixtures
�Without maintenance
�Without shrinkage
�With [relatively] zero cost to entry
� The Web changed everything

Before the cloud
� If you wanted to start an
enterprise, you needed an
IT shop
� Massive costs in hardware,
software, power,
administrative staff
� Prohibitive cost to entry

What if …
� You could have unlimited computing resources?
�All the processing power you want
�All the data storage you want
�Data mining whenever you want
� Cloud computing will be the biggest change to our industry since the rise of the Internet

Agenda
� Introduction
� Cloud computing services
� Principles of openness
� Where we go from here

16 An Introduction to Cloud Computing © 2009 IBM Corporation
Presented by IBM developerWorks
Cloud services
� There are four basic things people are doing in the cloud:
�Machines in the cloud
�Storage in the cloud
�Databases in the cloud
�Applications in the cloud
� In addition to these four basics, cloud providers offer other services such as message queues and data
mining
� All of these things are lumped into the generic term “cloud computing”
17 An Introduction to Cloud Computing © 2009 IBM Corporation
Presented by IBM developerWorks
Machines in the cloud
� Many cloud providers allow you to create a Virtual Machine (VM) and deploy it in the cloud
�Your VM images are stored in cloud storage
�You can create as many images as you need
�You can automatically start and stop running instances of those images as needed
� This is the simplest way to get started in the cloud, particularly if you’ve been using virtualization already
18 An Introduction to Cloud Computing © 2009 IBM Corporation
Presented by IBM developerWorks
Storage in the cloud
� Most cloud storage systems are designed as distributed, redundant systems
�Your data are stored on more than one disk in more than one place
�If one part of the system goes down, the rest of the system keeps going
�“There should never be a single point of failure” is a stated design goal
� But you can’t think of cloud storage as just another hard drive
19 An Introduction to Cloud Computing © 2009 IBM Corporation
Presented by IBM developerWorks
Databases in the cloud
� Cloud databases have similar design points
�Datasets are distributed for reliability
�Some cloud databases support schemas, some don’t
�Some cloud databases support joins, most don’t
�Some cloud databases are relational, almost all aren’t
�Some cloud databases are transactional, some aren’t
20 An Introduction to Cloud Computing © 2009 IBM Corporation
Presented by IBM developerWorks
Other services in the cloud
� A number of vendors provide message queuing services in the cloud
�Some queuing services don’t let you peek a message, for example
� Cloud data mining services use techniques such as Hadoop / MapReduce to analyze massive data sets
�Techniques that required supercomputers, large data centers and significant funds a few years ago can now be done for a few hundred pounds
� New businesses and business models will emerge based on the cost of data mining being reduced by several orders of magnitude

Cloud Computing Center at Wuxi
� The municipality of Wuxi, was working to
accelerate China’s transformation to a service economy
� IBM engaged the municipal government to develop a virtual data center linking several companies in a “software park”
� The public cloud implementation, China's
first commercial cloud, enabled by IBM technology and services will:
�Promote growth of software start-ups across China
�Accelerate development and test cycles
�Offer secure, network-isolated environments
�Deliver Backup and Restore asset protection capabilities

Cloud Computing in Agriculture
� Example from University of Melbourne
� Experimental farm using irrigation automation
�Irrigating short-term (minutes to hours)
�Predict micro-climate for coming week
�Predict market in coming months
� Interconnection of real-data with climate prediction
� Results are promising
�Orchid saw 300% increase in profitability
�Dairy farm saw 70% increase in profitability
�Local commercial dairy farm saw 70% increase in profitability

Vendor lock-in
� If there’s a new technology, any talented programmer will want to use it
�Maybe the shiny new thing is appropriate for what we’re doing
�Maybe not
�We’re probably going to use it anyway
� The challenge is to walk the line between using the newest, coolest thing and avoiding vendor lock-in

Issues with the Internet
� “It’s not secure.”
� “I don’t want to lose control of my infrastructure.”
� “I don’t know how reliable it is.”
� “I don’t know if my partners are going to use it.”
� All of these were important, legitimate issues
�With VPNs and other technology, the industry solved these problems

� “I don’t know how reliable it is.”
� “I don’t know if my partners are going to use it.”
� All of these are important, legitimate issues
�We’ve got some work to do, but the massive economic incentives mean someone will find a way to solve these problems

Key questions to ask
� Will cloud computing help create and deliver innovative business and consumer services to achieve greater competitive differentiation?
� Can cloud computing help to quickly achieve goals for IT
optimization, cost savings and faster time to market?
� Is competitive advantage gained by using cloud computing?
