I’m CloudConfused Demystifying Cloud Computing
What the say: “Biggest Paradigm Shift in 20 years” “Game Changers” “Just On” “Pay As You Go” “Tremendous Cost Cutting”

Who Cares? What is it for me?
First, What the heck is Cloud 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 Builda house or Rentan apartment
If you builda house, there are a few important 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 customizeit flooring tile windows floor plan Roof lighting landscaping
Once the house is built, you’re responsible for maintenance Pay property tax Hire Landscaper Water Electrician Electricity Plumber Heating and Cooling Gutter Cleaning House Keeping
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, simpler decisions You can start with one unit and grow later, or downsize
But… You do nothave 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 worryabout maintenance cost No need to Hirelandscapers, electricians, plumbers
Pay as You Go Just pay your rent and utilities
Let’s translate to Cloud Computing?
As an end-consumer, believe it or not you’ve been using Cloudfor long times
In return, you’re willing to give away your informationfor ads and other purposes
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
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 Support Software Upgrade 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 2010and beyond Global 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) Transparency Brief Collaboration (Blogs, Social Computing) (Assemble the best, Disassemble upon completion)
2008-09 Economy is upside down Layoffs Bankruptcy Excess Capacity
Requires aNew Way ofThinking
Cloud Computing is not answer the for all
Leave it the experts who have a lot of money to spend to build giantdatacenters 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 whereyour data and “servers” reside
Business Contraction? Just reduce your computing power,storage
Wait, What is the catch?
Cloud Computing is relatively newtechnology
Growing Pains We all learn from it
Only a handful of major players can build this massive infrastructure
Not many software written yet to takeadvantage of cloudinfrastructure
Sensitive Data in the Cloud? are there yet? Encryption Data at Rest Data in Motion
