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


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


Cloud characteristics

Rapid elasticityYou can go from 5 servers to 50 or from 50 servers to 5

Measured serviceYou pay for what you use

On-demand self-serviceYou get elasticity automatically

Ubiquitous network accessYou can access the cloud from anywhere

Location-independent resource poolingYou work with virtual machines that could be hosted anywhere

You’re on the cloud already

If you use Flickr or Facebook or LinkedIn or Twitter or Backpack or [insert hundreds of other sites here], you’re using the cloud

Cloud is a metaphor for the internet

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”


Machines in the cloud

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


Storage in the cloud

Most cloud storage systems are designed as distributed, redundant systemsYour 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


Databases in the cloud

Cloud databases have similar design pointsDatasets 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


Other services in the cloud

A number of vendors provide message queuing services in the cloudSome 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 setsTechniques 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


Amazon Elastic Compute Cloud

What is Amazon EC2?

Popular Uses for Amazon EC2

aws.amazon.com/ec2


Amazon Elastic Compute Cloud running IBM

Run many of the proven IBM platform technologies by the hour as Amazon Machine Images (AMIs) IBM DB2

IBM Informix

IBM Lotus Content Management

IBM Mashup Center

IBM WebSphere Application Server

IBM WebSphere sMash

Cloud implementation types


Cloud computing

Private Cloud

Client owned and managed.

Access limited to client and its partner network.

Drives efficiency, standardization and best practices while retaining greater customization and control.

Public Cloud

Service provider owned and managed.

Access by subscription.

Delivers select set of standardized business 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 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 promisingOrchid saw 300% increase in profitability

Dairy farm saw 70% increase in profitability

Local commercial dairy farm saw 70% increase in profitability

Machines in the cloudCan I move my VM elsewhere?

Storage in the cloudCan I move my data elsewhere?

Databases in the cloudCan I move my data elsewhere?

Applications in the cloudCan I run my application elsewhere?


Vendor lock-in

If there’s a new technology, any talented programmer will want to use itMaybe 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

Introduction




Resources


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 issuesWith VPNs and other technology, the industry solved these

problems


Issues with the cloud

“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 are important, legitimate issuesWe’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?
