I’m Cloud Confused

Demystifying Cloud Computing

What the say:

“Biggest Paradigm Shift in 20 years”

“Game Changers”

“Tremendous Cost Cutting”

“Just On”“Pay As You Go”


Describe The Cloud To Me

The Cloud


What is it for me?


First,

What the heck is

Cloud Computing

First, what the heck is

Cloud Computing?…in simple


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 few

important decisions you have to

make…


How big is the house?

are you planning to grow a large family?


But, you get a chance to customize it

tile

flooring

Roof floor plan

landscaping

windows

lighting


Once the house is built,

you’re responsible for maintenance

Hire Landscaper

ElectricianPlumber

Pay property tax

Water

Gutter Cleaning

Heating 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 convertedinto a 2,3……. or more units


You make a fewer,

simplerdecisions

You can start with one

unit and grow later, or

Downsize it


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, plumbers5/15/2012 Cloud Overview

Just pay your rentand utilities

Pay as You Go


Let’s translate this to

Cloud Computing ?


As an end-consumer, believe it or not

you’ve been using Cloud for long times

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, then

you can use this infrastructure for free


This is how their CEO would feel


My Business Needs…

Server Crashes


In the mean time,…

Many things have changed


The enterprise world we live in

2012 and beyond

Global Direct, Open Customers

Communication

Transparency

Work 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

2011-12Economy is upside down

Excess Capacity

Bankruptcy


Can we bridge the gap?


Requires

a New Way

of Thinking


Cloud Computing

is not

answerthe

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 replicated

3 or 4 times in their data center

High Availability 5/15/2012 Cloud Overview

Adding “servers” is a click away.

Running in just minutes, not daysHig

h T

raff

ic?


It can even load balance your server traffic


Expect your Cloud

Network

is always up


Yes, you can even pick

where your data

and “servers” reside


Business Contraction?

Just reduce your

computing power, storage


Only a handful of major players

can build

this massive infrastructure

Not many software written yet to take

advantage 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 APIs5/15/2012 Cloud Overview

Let’s clear common confusionsabout Cloud Computing


Who is paying whom?


Typical Scenarios

You

(Business, Individual)

Software/Service

Providers Cloud/Infrastructure

Provider

You may also build software

directly on the provider’s platform and

pay 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 architectures

and business model

Cloud Players Hosting Players

Only few can afford billions dollar

investment on data centers

Hundreds of them around

the world

Pay As You Go

Pay only what you use 5/15/2012 Cloud Overview

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 rent

servers to increase capacity


The end of PC ?


Most cloud applications that will be built are

accessible from PC. Applications can be a browser base, application

running on PC accessing data and services on the cloud

NO

So will the mobile applications
