Cloud computing : opportunities and issues - GOVIS 22 sept 2010

  1. 1. Cloud Computing: Opportunities & Issues GOVIS 22nd September 2010 Clifton Chan CROWN COPYRIGHT ©
  2. 2. What is Cloud Computing? http://www.flickr.com/photos/10657705@N003252076269
  3. 3. Cloud Computing Nutshell  Is a way to outsource ICT, with its own characteristics • On-demand self-service • Broad network access • Resource pooling – multi-tenanted • Rapid elasticity – scale fast • Measured service  Entered into if the benefits outweigh the total costs and risks
  4. 4. Self-service ? http://www.flickr.com/photos/sinanyuzakli/3631243681
  5. 5. Self-service http://www/flickr/com/photos/tea_time/3942238453/
  6. 6. Broad network access http://www.flickr.com/photos/jurvetson/916142
  7. 7. Resource Pooling: multi-tenanted http://www.flickr.com/photos/kanjiroushi/2459038965
  8. 8. Rapid elasticity: scale fast http://www.flickr.com/photos/jamescridland/613445810
  9. 9. Measured service http://www/flickr/com/photos/tea_time/3942238453/
  10. 10. What ‘services’ can I ‘buy’? http://www.flickr.com/photos/10657705@N003252076269
  11. 11. Cloud Services  Business Process as a Service • E.g. HR system (legally compliant)  Software as a Service • E.g. Email, Social networking, CRM  Platform as a Service • E.g. Payments, web site and databases  Infrastructure as a Service • E.g. Networks, servers and storage
  12. 12. Cloud Computing Recap  Is a way to outsource ICT, with its own characteristics • On-demand self-service • Broad network access • Resource pooling – multi-tenanted • Rapid elasticity – scale fast • Measured service  Entered into if the benefits outweigh the total costs and risks

  16. 16. Mainframe Bureaus M/F Bureaus Comment On-demand self-service Face-to-face  engagement process Broad network access Need to put the network ? in, or use dial-up Resource pooling  Rapid elasticity Vendor needs to ? schedule clients Measured service   Cloud like – just  Internet provides the network  Web 2.0 enables self-service

  18. 18. The Nutshell (again)  Is a way to outsource ICT, with its own characteristics • On-demand self-service • Broad network access • Resource pooling – multi-tenanted • Rapid elasticity – scale fast • Measured service  Entered into if the benefits outweigh the total costs and risks
  19. 19. Self-service http://www/flickr/com/photos/tea_time/3942238453/
  20. 20. Self-service Rapid deployment  Uncontrolled proliferation
  21. 21. Broad network access http://www.flickr.com/photos/jurvetson/916142
  22. 22. Broad network access  i.e. the Internet Deploy and access „anywhere‟  Totally dependent on the Internet – a best endeavours network  Another hole in your corporate perimeter
  23. 23. Resource pooling: multi-tenanted http://www.flickr.com/photos/kanjiroushi/2459038965
  24. 24. Resource pooling: multi-tenanted  Everything hosted on the cloud  Vendor manages technology and operations Benefit from volumes of scale Manage service and outcomes  No customisation  Vendor dictates upgrades
  25. 25. Rapid elasticity: scale fast http://www.flickr.com/photos/jamescridland/613445810
  26. 26. Rapid elasticity: scale fast No need to provision for peaks No idle assets – 100% ROI Less reliance on CapEx
  27. 27. Measured service http://www/flickr/com/photos/tea_time/3942238453/
  28. 28. Measured service Pay for what you use Pay as you go Direct linkage between usage and cost – management tool Smooth expenditure profile  Hard to unwind Capex-to-OpEx shift

  31. 31. Elephant in the room Obligations Data Legal http:// www.flickr.com/photos/mobilestreetlife/4179063482
  32. 32. Data Obligations  Data is outside your corporate custodianship – maybe off-shore.  How secure is your data? – total reliance on vendor  XaaS – you may not have the right to access the underlying data  Data ownership  Can you meet all of your legal obligations ?
  33. 33. Legal Obligations  Large cloud computing providers are multi-nationals  What contract law applies ?  What data protection laws apply ?  What 'lord of the manor' rights exist ?  Can you meet all of your legal obligations ?
  34. 34. The Nutshell (again)  Is a way to outsource ICT, with its own characteristics • On-demand self-service • Broad network access • Resource pooling – multi-tenanted • Rapid elasticity – scale fast • Measured service  Entered into if the benefits outweigh the total costs and risks
