Before the Web

If you wanted to sell things tothe public, you needed astorefront

Massive cost in real estate,fixtures, maintenance,shrinkage

Prohibitive cost to entry


4/36



What if

You could have hundreds of millions of storefrontsworldwide?

Without real estate

Without fixtures

Without maintenance

Without shrinkageWith [relatively] zero cost to entry

The Web changed everything


5/36



Before the cloud

If you wanted to start anenterprise, you needed an

IT shop Massive costs in hardware,

software, power,administrative staff

Prohibitive cost to entry


6/36



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

Cloud characteristics

Rapid elasticity

You can go from 5 servers to 50 or from 50 servers to 5

Measured service

You pay for what you use

On-demand self-service

You get elasticity automatically

Ubiquitous network access

You can access the cloud from anywhere

Location-independent resource pooling

You work with virtual machines that could be hosted anywhere

using the cloud Cloud is a metaphor for the internet

Cloud services

There are four basic things people are doing in thecloud:

Machines in the cloudStorage in the cloud

Databases in the cloud

Applications in the cloud

In addition to these four basics, cloud providers offerother services such as message queues and data

mining

All of these things are lumped into the generic termcloud computing


17/36



Machines in the cloud

Many cloud providers allow you to create a VirtualMachine (VM) and deploy it in the cloud

Your VM images are stored in cloud storageYou can create as many images as you need

You can automatically start and stop running instances of thoseimages as needed

This is the simplest way to get started in the cloud,particularly if youve been using virtualization already


18/36



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 oneplace

If one part of the system goes down, the rest of the system keepsgoing

There should never be a single point of failure is a stated designgoal

But you cant think of cloud storage as just another

hard drive


19/36




Cloud databases have similar design points

Datasets are distributed for reliability

Some cloud databases support schemas, some dontSome cloud databases support joins, most dont

Some cloud databases are relational, almost all arent

Some cloud databases are transactional, some arent


20/36



Other services in the cloud

A number of vendors provide message queuingservices in the cloud

Some queuing services dont let you peek a message, forexample

Cloud data mining services use techniques such asHadoop / MapReduce to analyze massive data sets

Techniques that required supercomputers, large data centers andsignificant funds a few years ago can now be done for a fewhundred pounds

New businesses and business models will emergebased on the cost of data mining being reduced byseveral orders of magnitude

Cloud implementation types


24/36



Cloud computing

Private Cloud

Client owned and managed.

Access limited to client and itspartner network.

Drives efficiency, standardizationand best practices while retaining

greater customization and

control.

Public Cloud

Service provider owned andmanaged.

Access by subscription.

Delivers select set of standardizedbusiness process, application

and/or infrastructure services on

a flexible pay per use basis.

Customization

Efficiency

Security and Privacy

Availability

Standardization

Capital preservation

Flexibility

Time to deploy

Cloud Computing Center at Wuxi

The municipality of Wuxi, was working to

accelerate Chinas transformation to aservice economy

IBM engaged the municipal governmentto develop a virtual data center linkingseveral companies in a software park

The public cloud implementation, China's

first commercial cloud, enabled by IBMtechnology and services will:

Promote growth of software start-upsacross China

Accelerate development and test cycles

Offer secure, network-isolatedenvironments

Deliver Backup and Restore assetprotection 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 theres a new technology, any talented programmerwill want to use it

Maybe the shiny new thing is appropriate for what were doingMaybe not

Were probably going to use it anyway

The challenge is to walk the line between using thenewest, coolest thing and avoiding vendor lock-in

Issues with the Internet

Its not secure.

I dont want to lose control of my infrastructure.

I dont know how reliable it is.

I dont know if my partners are going to use it.

All of these were important, legitimate issuesWith VPNs and other technology, the industry solved these

problems

Issues with the cloud

Its not secure.

I dont want to lose control of my infrastructure.

I dont know how reliable it is.

I dont know if my partners are going to use it.

All of these are important, legitimate issuesWeve got some work to do, but the massive economic incentives

mean someone will find a way to solve these problems



35/36



Key questions to ask

Will cloud computing help create and deliver innovativebusiness 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 cloudcomputing?
