Cloud computing for SMBs

  1. 1. Cloud  Computing  For  SMBs   Krishnan  Subramanian   Analyst  &  Editor,  CloudAve  
  2. 2. It  is  cloud  computing  to  most  of  us  
  3. 3. Plan  of  my  talk  *  Cloud  Computing  –  What,  Why,  How  and   Who?  *  Potential  Security  and  Privacy  Concerns  &   Best  Practices  *  Conclusion  
  4. 4. Computing  Evolution  
  5. 5. Cloud  Computing  –  Many  Definitions   *  On-­‐demand  self-­‐service  internet  infrastructure  where  you   pay  as  you  go  and  use  only  what  you  need,  all  managed  by   a  browser,  application  or  API   *  Clouds  will  be  the  next  transformation  over  the  next   several  years,  building  off  of  the  software  models  that   virtualization  enabled   *  +  100s  more  from  experts,  vendors  and  kids  
  6. 6. NIST  Definition  of  Cloud  Computing  Cloud   computing   is   a   model   for  enabling   convenient,   on-­‐demand  network   access   to   a   shared   pool   of  configurable   computing   resources  (e.g.,   networks,   servers,   storage,  applications,   and   services)   that   can   be  rapidly   provisioned   and   released   with  minimal   management   effort   or   service  provider  interaction.    
  7. 7. Essential  Characteristics   *  On-­‐Demand   *  Self  Service   *  Location  and  Device  independence   *  Multi-­‐tenancy   *  Rapid  Elasticity   *  Pay  as  you  go  model    
  8. 8. On  Demand  
  9. 9. Self  Service  
  10. 10. Location  &  Device  Independence  
  11. 11. Multi-­‐tenant  
  12. 12. Rapid  Elasticity  
  13. 13. Pay  Per  Use  
  14. 14. Cloud  Delivery  Models  Applications   Middleware*   Servers**  
  15. 15. Cloud  Deployment  Models  
  16. 16. NIST  Cloud  Model  
  17. 17. Prominent  Cloud  Providers  
  18. 18. Business  Advantages    *  Cost  Savings  –  No  Capex  and  Lower  Opex  *  Agility  –  Faster  Business  Response  To  Changing   Conditions    *  Focus  on  Core  Business    
  19. 19. How  Big  Will  Be  The  Cloud  Market?  
  20. 20. Analyst  Predictions  1)  The  industry  is  poised  for  strong  growth  through  2014,  when   worldwide  cloud  services  revenue  is  projected  to  reach  $148.8  billion  –   Gartner,  June  2010  2)  Public  IT  cloud  will  be  over  25%  of  the  net-­‐new  growth  in  traditional  IT   products  between  now  and  2014  –  IDC,  June  2010  3)  The  global  market  for  enterprise  cloud-­‐based  services  will  grow  from   $12.1  billion  in  2010  to  $35.6  billion  in  2015  –  Analysys  Mason,  2010  4)  IaaS,  PaaS  and  SaaS  software  and  services  sales  globally  accounted  for   $20.3  billion  in  2009,  predicting  a  market  size  of  $100.4  billion  by  2016  –   Wintergreen  Research  
  21. 21. Is  Cloud  A  Cure  For  IT  Headaches?     Yes   But  some  people  seem  to   have  security  &  privacy   concerns  
  22. 22. Cloud  Is  Not  Secure?  
  23. 23. Security  &  Privacy  Concerns  * Cloud  Provider’s  Security  Practices  * Regulatory  Needs  * Data  Ownership  * Data  Privacy  
  24. 24. Mental  Shift      Losing  Control   Trust  
  25. 25. In  Reality  *  Cloud  is  neither  more  nor  less  secure  than  the   traditional  IT.  But  in  the  case  of  most  SMBs,  Cloud   provides  better  security  *  With  the  loss  of  control,  different  kind  of  risks  comes   into  focus  *  Industry  best  practices  can  help  mitigate  these  risks.   Check  out  Cloud  Security  Alliance  (CSA)  *  Bottom  Line  is  balancing  the  risks  to  take  advantage   of  the  clouds  
  26. 26. Vendor  Responsibility  
  27. 27. Conclusion  *  Cloud  is  real  and  maturing  fast.   Businesses  of  all  sizes  and  shapes   are  going  to  adopt  it  much  sooner   than  many  expect  *  Using  Cloud  Computing  becomes  a   competitive  advantage  *  A  big  part  of  the  security  concerns   are  due  to  FUD  but  it  is  also  critical   to  understand  the  risks  and  take   steps  to  mitigate  them,  to  take  the   full  advantage  of  clouds  *  Leverage  the  cloud  but  control  your   destiny
