1. A  View  of  Cloud   Computing   Tiago  Posse   Nº  37068   03/12/2012      
2. Cloud  de2inition     •  Applica8ons  delivered  over  the  internet  (so@ware)     •  Data  center  that  provides  the  services  (hardware)   •  U8lity  compu8ng   •  Public  vs  Private  cloud  
3. Advantages   •  Pay-­‐as-­‐you-­‐go   •  Elas8city   •  Appearance  of  infinite  resources   •  Highly  customizable  in  some  cases  
4. Elasticity   •  Peaks     •  Scaling  up  and  down  on  demand   •  Cost-­‐efficient   •  No  risk  of  overprovisioning  or  underprovisioning  due  to  peak   workloads   •  Leads  to  less  customer  loss  
5. Problems   •  Abstrac8ons   •  Data  center  availability   •  Data  security   •  Transfer  data  between  data  centers   •  Performance   •  Scale  storage  on  demand   •  Large  scale  systems  errors   •  Reputa8on   •  So@ware  Licensing  
6. Conclusions   •  Cloud  is  a  revolu8onary  technology  with  several  advantages   over  tradi8onal  compu8ng   •  Elas8city   •  Pay-­‐as-­‐you-­‐go   •  Adaptable  to  several  scenarios     •  S8ll  has  problems  to  solve
