Computing  Evolution  

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

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.    

Essential  Characteristics  

*  On-­‐Demand  *  Self  Service  

*  Location  and  Device  independence  *  Multi-­‐tenancy  *  Rapid  Elasticity  

*  Pay  as  you  go  model

How  Big  Will  Be  The  Cloud  Market?  

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  

Is  Cloud  A  Cure  For  IT  Headaches?  

 

Yes  But  some  people  seem  to  have  security  &  privacy  

concerns  

Cloud  Is  Not  Secure?  

Security  &  Privacy  Concerns  

* Cloud  Provider’s  Security  Practices  * Regulatory  Needs  * Data  Ownership  * Data  Privacy  

Mental  Shift  

   

Losing  Control  Trust  

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  

Vendor  Responsibility  

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
