Mr. Simon Ponsford's presentation at QITCOM 2011

  1. 1. When Does It Make Sense to Use the Cloud?<br />Technical, economic and environmental considerations<br />Simon Ponsford<br />Senior Scientist – Cloud Computing<br />QCRI<br />
  2. 2. Cloud Computing - Definition<br />What Is Cloud Computing?<br />Infinitely scalable shared computing resources available on demand via the Internet where the user is charged only for what they use. <br /> —Simon Ponsford, QCRI <br />Public Cloud<br />Made available to the general public.<br />Private Cloud<br />Datacenter of a business or organization e.g. the UK government intends to migrate the 500 existing government server rooms datacenters into 12 datacenters.<br />If a business simply virtualizes servers this is not a private Cloud<br />
  3. 3. Cloud Computing Advantages<br />The Advantages<br />Highly available<br />On demand – enterprise quality computing resources<br />No requirement to employ datacenter staff<br />No capital outlay<br />Rapid access to resources<br />Allows entrepreneurs to build and test new ideas without the need to invest in infrastructure or require set-up expertise<br />Who Is Involved Today?<br />The main players: <br /><ul><li>Amazon Web Services
  4. 4. Microsoft Azure
  5. 5. Google
  6. 6. A host of smaller localized organizations developing and operating Cloud-based services.</li></li></ul><li>The Reality<br />Not cheap – probably triple the cost of buying a server, installing and maintaining it.<br />Not fast – particularly disk access. E.g. Amazon EC2 usage of EBS storage 18 MB per second, a new HP server, e.g. DL360 with SAS disks, 400 MB per second read and write<br />Difficult to estimate pricing e.g. pay per RAM hour, GB storage, CPU Core, disk I/O, database transaction, bandwidth usage and operating system. How do you know how many transactions you are going to do in a month? It is so complex there is a market for applications to calculate costs, and businesses reselling Cloud Services with more traditional cost structures.<br />No open standards for Clouds<br />Migration between different Cloud providers is difficult<br />So where is it a good fit?<br />
  7. 7. Case Study – Bumper Sticker<br />LinkedIn’s Cloud Computing Experiment <br /><ul><li>LinkedIn wanted to test rapid application development and Cloud scaling.
  8. 8. Built an application called “Bumper Sticker” in 2008. Allowed a bumper sticker to be added to a Facebook profile.
  9. 9. Used Joynet – Cloud Service provider.
  10. 10. Reached 1 million users in first 46 days.
  11. 11. 13.5 million installations.
  12. 12. At height, 1 billion page views per month.</li></li></ul><li>Cloud Computing – Accommodates the Unknown<br />If you don’t know, go Cloud<br /><ul><li>Business unknowns
  13. 13. How successful will I be?
  14. 14. No longer need to overprovision when purchasing IT systems
  15. 15. If your requirements level out, you may want to switch to a hosted or onsite solution to save costs.</li></li></ul><li>Improve Utilization<br />Greener?<br />In April 2010, VivekKundra, US Federal Chief Information Officer, said in reference to the 1,200 datacentres run by the government:<br />“One of the most troubling aspects about the data centres is that in a lot of these cases, we’re finding that server utilization is actually around 7%.” Industry average is 15-20%. <br />Google achieves more than 50%; Amazon is similar. These result in significant energy saving.<br />
  16. 16. THANK YOU<br />
