I’m CloudConfused<br />Demystifying Cloud Computing
<br />

What the say:<br />“Biggest Paradigm
Shift in 20 years”<br />“Game Changers”<br />“Just On”<br />“Pay As You Go”<br />“Tremendous Cost Cutting”<br />

Describe The Cloud To Me<br

Who Cares?<br />What is it
for me? <br />

First, <br />What the heck
is<br />Cloud Computing<br />First, what the heck is <br />Cloud Computing?<br />…in simple, plain English please!<br />

Let’s use a simple analogy
<br />Say you just moved to a city, and you’re looking for <br />a place to live<br />

You can either<br />Builda house
or <br />Rentan apartment<br />

If you builda house, there
are a few<br />important decisions you have to make…<br />

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

But, you get a chance
to customizeit<br />flooring<br />tile<br />windows<br />floor plan<br />Roof<br />lighting<br />landscaping<br />

Once the house is built,
<br />you’re responsible for maintenance <br />Pay property tax<br />Hire Landscaper<br />Water<br />Electrician<br />Electricity<br />Plumber<br />Heating and Cooling <br />Gutter Cleaning<br />House Keeping<br />

How about renting?<br />

Consider a builder in your
city builds <br />a massivenumber of apartment units <br />

A unit can easilybe converted
<br />into a 2,3,4 or more units<br />

You make a fewer, simpler<br
/>decisions<br />You can start with one unit and grow later, or<br />downsize<br />

But…<br />You do nothave<br />a
lot of options to <br />customize your unit <br />

triple pane windows<br />green materials<br
/>high capacity electricity<br />high speed Internet<br />However, builders provide you with very high quality infrastructure <br />

No need to worryabout maintenance
cost<br />No need to Hirelandscapers, electricians, plumbers<br />

Pay as You Go<br />Just
pay your rent<br />and utilities <br />

Let’s translate to <br />Cloud
Computing?<br />

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

Yes, most of them are
<br />Free<br />

In return, you’re willing to
give away<br />your informationfor ads and other purposes <br />

But you’ve been enjoying <br
/>High Reliability Service<br />(ok, ok, most of them are)<br />Unlimited Storage<br />Connecting, Sharing<br />

OK, Now tell that to
the business owner<br />Give up your data, then<br />you can use this infrastructure for free <br />

This is how their CEO
would feel<br />

My Business Needs…<br />Security<br />Privacy<br
/>Reliability<br />High Availability<br />

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

Let’s Hire an Army of
IT Engineers<br />Support<br />Software Upgrade<br />Backup/Restore<br />Service Pack<br />Development<br />Network issues<br />

Let’s Build<br />Huge Data Center<br
/>Capacity Planning<br />Cooling Management <br />Disaster Plan<br />Server Crashes<br />

In the mean time,… <br
/>Many things have changed <br />

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

2008-09<br />Economy is upside down<br
/>Layoffs<br />Bankruptcy <br />Excess Capacity<br />

Can we bridge the gap?
<br />

Requires <br />aNew Way<br />ofThinking<br
/>

Cloud Computing <br />is not<br
/>answer<br />the<br />for all <br />

But it could simplifyour lives….<br
/>

Leave it the experts<br />who
have a lot of money to spend to build <br />giantdatacenters across the globe<br />

Your data is replicated<br />3
or 4 times in their data center<br />High Availability <br />

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

It can even load balance
<br />your server traffic<br />

Expect your Cloud<br />Network<br />is
always up<br />

Yes, you can even pick
<br />whereyour data <br />and “servers” reside <br />

Business Contraction?<br />Just reduce your
<br />computing power,storage<br />

Wait, <br />What is the
catch?<br />

Cloud Computing <br />is relatively
newtechnology <br />

Growing Pains<br />We all learn
from it<br />

Only a handful of major
players<br />can build <br />this massive infrastructure<br />

Not many software written yet
to takeadvantage of cloudinfrastructure<br />

Sensitive Data in the Cloud?<br
/>are there yet? <br />Encryption<br />Data at Rest<br />Data in Motion<br />

Yes, you’re loosing some controls
<br />some configurations<br />physical security<br />only subset of APIs<br />

Let’s clear common confusions<br />about
Cloud Computing<br />

Who is paying whom? <br
/>

Typical Scenarios<br />Software/Service<br />Providers<br />Cloud/Infrastructure<br
/>Provider<br />You<br />(Business, Individual)<br />You may also build software<br />directly on the provider’s platform and<br />pay them directly <br />

Do I have to start
over? <br />

In some cases, <br />you
could redirectyour data to the cloud <br />Before<br />Migrate Data to the Cloud<br />

In some cases, <br />you
could redirectyour data to the cloud <br />After<br />

However, to take advantage fully,
migrate all or create new apps on the cloud<br />Employees<br />Suppliers<br />Customers<br />

Is this just Hosting 2.0?
<br />

No, they have different architecturesand
business model<br />Cloud Players<br />Hosting Players<br />Hundreds of them around<br />the world<br />Only few can afford billions dollar <br />investment on data centers <br />

Your contracts<br />Cloud Players<br />Hosting
Players<br />Pay As You Go<br />Often yearly<br />Pay only what you use <br />

Reliability, High Availability, <br />Capacity
Elasticity<br />Cloud Players<br />Hosting Players<br />Bring your own or rent<br />servers to increase capacity<br />Virtually unlimited storage, computing power<br />You have to manage <br />reliability, fail over yourself<br />Built-in Redundancy<br />

The end of PC ?
<br />

NO<br />Most cloud applications that
will be built are <br />accessible from PC. <br />Applications can be a browser base, applicationrunning on PC accessing data and services on the cloud<br />So will the mobile applications<br />
