Demystifying Cloud Computing

What the say:

“Biggest Paradigm Shift in 20 years”

“Game Changers”
“Just On”
“Pay As You Go”
“Tremendous Cost Cutting”

5/15/2012 Cloud Overview

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

flooring
tile windows
Roof floor plan

lighting landscaping

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

Hire Landscaper House Keeping Pay property tax
Heating and Cooling Electrician
Water
Plumber
Gutter Cleaning


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……. or more units


You make a fewer,

simpler
decisions
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


triple pane windows

green materials

high capacity electricity

high speed Internet

However, builders provide you with
very high quality infrastructure

No need to worry about maintenance cost

No need to Hire landscapers,
electricians, plumbers

Pay as You Go

Just pay your rent
and utilities


Let’s translate this 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
Free
Free
.
.

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

Unlimited Storage

Connecting, Sharing


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…

Security
Privacy

Reliability

High Availability

Building Enterprise
Software
is like….
Building
Medieval
Castle
Stone Wall
Fire-proof
Moat
Army
Death Hole

Let’s Hire an Army of IT Engineers

Software Upgrade
Support
Backup/Restore
Service Pack
Development Network issues

Let’s Build
Huge Data Center

Capacity Planning
Cooling Management
Disaster Plan

Server Crashes


In the mean time,…

Many things have changed


The enterprise world we live in
2012 and beyond
Global Direct, Open Customers
(Customers, Resources, IPs are acquired everywhere) Communication
(e.g. Social Media)

Digital Life Convergence
(Work and Personal lines are blurring)
Work Remotely
(Mobility Trend)

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

2011-12
Economy is upside down

Layoffs Bankruptcy
Excess Capacity

Can we bridge the gap?


Requires

a New Way
of Thinking


Cloud Computing

is not

the answer
for all

But it could simplify our lives….


Leave it the experts
who 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

High Traffic?

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

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?

Encryption
Data at Rest

Data in Motion

Yes, you’re loosing some controls
some configurations
physical security

only subset of APIs

Let’s clear common confusions
about Cloud Computing


Who is paying whom?


Typical Scenarios
Software/Service
Providers Cloud/Infrastructure
Provider

You You may also build software
directly on the provider’s platform and
(Business, Individual) pay them directly


Do I have to start over?


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

Before
Migrate Data to the Cloud

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

Suppliers

Customers Overview
5/15/2012 Cloud

Is this just Hosting 2.0?


No, they have different architectures
and business model

Cloud Players Hosting Players

Hundreds of them around
the world

Only few can afford billions dollar
investment on data centers

Your contracts


Pay As You Go

Often yearly

Pay only what you use

Reliability, High Availability,
Capacity Elasticity


Virtually unlimited Bring your own or rent
storage, computing power servers to increase capacity
You have to manage
Built-in Redundancy reliability, fail over yourself


The end of PC ?


NO
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

So will the mobile applications
