The Cloud

Who Cares?

What is it for me?

First, What the heck isCloud Computing

First, what the heck is Cloud Computing?…in simple, plain English please!

Let’s use a simple analogy

Say you just moved to a city, and you’re looking for a place to live

You can either

Build a house or Rent an apartment

If you build a house, there are a fewimportant decisions you have to make…

How big is the house?

are you planning to grow a large family? Remodel, addition typically cost a lot more once the house is built

But, you get a chance to customize it

tileflooring

Roof floor plan

landscaping

windows

lighting

Once the house is built, you’re responsible for maintenance

Pay property taxElectricity Water

Gutter CleaningHeating and Cooling House Keeping

How about renting?

Consider a builder in your city builds

a massive number of apartment units

A unit can easily be converted into a 2,3,4 or more units

You make a fewer,

simpler decisions

You can start with one unit and grow later, ordownsize

But…You do not have

a lot of options to customize your unit

However, builders provide you with

very high quality infrastructure

high speed Internet

high capacity electricity

triple pane windows

green materials

No need to worry about maintenance cost

No need to Hire landscapers, electricians, plumbers

Just pay your rentand utilities

Pay as You Go

Let’s translate to Cloud Computing?

As an end-consumer, believe it or not you’ve been using Cloud for long times

Yes, most of them are

Free

In return, you’re willing to give away

your information for ads and other purposes

But you’ve been enjoying High Reliability Service

Unlimited Storage

Connecting, Sharing

(ok, ok, most of them are)

OK, Now tell that to the business owner

Give up your data, thenyou can use this infrastructure for

free

This is how their CEO would feel

In the mean time,…

Many things have changed

The enterprise world we live in 2010 and beyond

Global Direct, Open CustomersCommunication

TransparencyWork Remotely

Digital Life Convergence(e.g. Social Media)

(Work and Personal lines are blurring)

(Customers, Resources, IPs are acquired everywhere)

(Mobility Trend)

(Blogs, Social Computing) Brief Collaboration(Assemble the best, Disassemble upon completion)

Layoffs

2008-09Economy is upside down

Excess CapacityBankruptcy

Can we bridge the gap?

Requires a New Wayof Thinking

Cloud Computing is notanswerthe

for all

But it could simplify our lives….

Leave it the expertswho have a lot of money to spend to build

giant datacenters across the globe

Your data is replicated3 or 4 times in their data center

High Availability

Adding “servers” is a click away. Running in just minutes, not daysHi

gh Tr

affic?

It can even load balance your server traffic

Expect your Cloud

Networkis always up

Yes, you can even pick where your data

and “servers” reside

Business Contraction?

Just reduce your computing power, storage

Wait, What is the catch?

Cloud Computing is relatively new technology

Growing Pains

We all learn from it

Only a handful of major playerscan build

this massive infrastructure

Not many software written yet to takeadvantage of cloud infrastructure

Sensitive Data in the Cloud?are there yet?

Data at Rest

Data in Motion

Encryption

Yes, you’re loosing some controls

physical securitysome configurations

only subset of APIs

Let’s clear common confusionsabout Cloud Computing

Who is paying whom?

Typical Scenarios

You(Business, Individual)

Software/ServiceProviders

Cloud/InfrastructureProvider

You may also build softwaredirectly on the provider’s platform andpay them directly

Do I have to start over?

In some cases, you could redirect your data to the cloud

Migrate Data to the Cloud

Before

In some cases, you could redirect your data to the cloud

After

However, to take advantage fully, migrate all or create new apps on the cloud

Employees

Customers

Suppliers

Is this just Hosting 2.0?

No, they have different architecturesand business model

Cloud Players Hosting Players

Only few can afford billions dollar investment on data centers

Hundreds of them aroundthe world

Hosting Players

Often yearly

Your contracts

Cloud Players

Pay As You Go

Pay only what you use

Hosting Players

Reliability, High Availability, Capacity Elasticity

Cloud Players

Built-in Redundancy

Virtually unlimited storage, computing power

You have to manage reliability, fail over yourself

Bring your own or rentservers to increase capacity

The end of PC ?

Most cloud applications that will be built are accessible from PC. Applications can be a browser base, applicationrunning on PC accessing data and services on the cloud

NO

So will the mobile applications
