Who Cares?What is it for me?

First, What the heck isCloud ComputingFirst, 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 eitherBuilda house or Rentan apartment

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

Howbigis 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 customizeitflooringtilewindowsfloor planRooflightinglandscaping

Once the house is built, you’re responsible for maintenance Pay property taxHire LandscaperWaterElectricianElectricityPlumberHeating and Cooling Gutter CleaningHouse Keeping

How about renting?

Consider a builder in your city builds a massivenumber of apartment units

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

You make a fewer, simplerdecisionsYou can start with one unit and grow later, ordownsize

But…You do nothavea lot of options to customize your unit

No need to worryabout maintenance costNo need to Hirelandscapers, electricians, plumbers

Pay as You GoJust pay your rentand utilities

Let’s translate to Cloud Computing?

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

Yes, most of them are Free

In return, you’re willing to give awayyour informationfor ads and other purposes

But you’ve been enjoying High Reliability Service(ok, ok, most of them are)Unlimited StorageConnecting, Sharing

OK, Now tell that to the business ownerGive up your data, thenyou can use this infrastructure for free

This is how their CEO would feel

My Business Needs…SecurityPrivacyReliabilityHigh Availability

In the mean time,… Many things have changed

The enterprise world we live in 2010and beyondGlobal Direct, Open CustomersCommunication(Customers, Resources, IPs are acquired everywhere)(e.g. Social Media)Digital Life Convergence(Work and Personal lines are blurring)Work Remotely(Mobility Trend)TransparencyBrief Collaboration(Blogs, Social Computing)(Assemble the best, Disassemble upon completion)

2008-09Economy is upside downLayoffsBankruptcy Excess Capacity

Can we bridgethe gap?

Requires aNew WayofThinking

Cloud Computing is notanswerthefor all

But it could simplifyour lives….

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

Your data is replicated3 or 4 times in their data centerHigh Availability

High Traffic?Adding “servers” is a click away. Running in just minutes, not days

It can even load balance your server traffic

Expect your CloudNetworkis always up

Yes, you can even pick whereyour data and “servers” reside

Business Contraction?Just reduce your computing power,storage

Wait, What is the catch?

Cloud Computing is relatively newtechnology

Growing PainsWe all learn from it

Only a handful of major playerscan build this massive infrastructure

Not many software written yet to takeadvantage of cloudinfrastructure

Sensitive Data in the Cloud?are there yet? EncryptionData at RestData in Motion

Yes, you’re loosing some controls some configurationsphysical securityonly subset of APIs

Let’s clear common confusionsabout Cloud Computing

Who is paying whom?

Typical ScenariosSoftware/ServiceProvidersCloud/InfrastructureProviderYou(Business, Individual)You may also build softwaredirectly on the provider’s platform andpay them directly

Do I have to start over?

In some cases, you could redirectyour data to the cloud BeforeMigrate Data to the Cloud

In some cases, you could redirectyour data to the cloud After

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

Is this just Hosting 2.0?

No, they have different architecturesand business modelCloud PlayersHosting PlayersHundreds of them aroundthe worldOnly few can afford billions dollar investment on data centers

Your contractsCloud PlayersHosting PlayersPay As You GoOften yearlyPay only what you use

Reliability, High Availability, Capacity ElasticityCloud PlayersHosting PlayersBring your own or rentservers to increase capacityVirtually unlimited storage, computing powerYou have to manage reliability, fail over yourselfBuilt-in Redundancy

The end of PC ?

NOMost 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 cloudSo will the mobile applications
