    • 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”
    • Describe The Cloud To Me
      The Cloud
      21 experts are defining cloud computing http://bit.ly/C6jIm

    • 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
    • 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, 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
    • 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
      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
      Direct, Open CustomersCommunication
      Global
      (e.g. Social Media)
      (Customers, Resources, IPs are acquired everywhere)
      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
    • Can we bridge the gap?
    • Requires
      aNew Way
      ofThinking
    • Cloud Computing
      is not
      answer
      the
      for all
    • But it could simplifyour lives….
    • 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
    • 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
      (Business, Individual)
      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 redirectyour data to the cloud
      Before
      Migrate 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 cloud
      Employees
      Suppliers
      Customers
    • Is this just Hosting 2.0?
    • No, they have different architecturesand business model
      Cloud Players
      Hosting Players
      Hundreds of them around
      the world
      Only few can afford billions dollar
      investment on data centers
    • Your contracts
      Cloud Players
      Hosting Players
      Pay As You Go
      Often yearly
      Pay only what you use
    • Reliability, High Availability,
      Capacity Elasticity
      Cloud Players
      Hosting Players
      Bring your own or rent
      servers to increase capacity
      Virtually unlimited storage, computing power
      You have to manage
      Reliability, fail over yourself
      Built-in Redundancy
    • 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
