Partly  Cloudy:  The  Forecast  for  Your  Technology    

Tom  Hollingsworth  @NetworkingNerd  CCIE  #29213,  VCP5  

What  Is  “The  Cloud”?  •  CompuBng  as  a  service,  not  a  product  •  OS  &  Device  Independent  •  Reliability  and  Scalability  •  Allows  Focus  on  Your  Goals,  Not  Technology  

Haven’t  I  Seen  This  Before?  •  ApplicaBon  Service  Providers  •  Hosted  SoluBons  •  Service-­‐Oriented  Architechture  

Not  A  Dirty  Word  •  *aaS  –  (something)  as  a  Service  •  SaaS  –  ApplicaBon  (Office  365,  Google  Apps)  •  PaaS  –  PlaXorm  (MicrosoZ  Azure)  •  IaaS  –  Infrastructure  (like  Amazon  EC2)  

•  ITaaS  –  IT  Outsourcing  (Managed  Services)  

Public  or  Private?  

Public  Cloud  

•  Hosted  somewhere  else  •  Accessed  via  the  Internet  •  Pay-­‐per-­‐use  

Private  Cloud  

•  Hosted  Internally  •  Secure  access  via  internal  network  •  More  Up  Front  Costs  

Public  Pricing  As  of  2/7/2012  

Who’s  Data  Is  It?  •  Data  on  someone’s  servers  –  Who  Owns  It?  •  Where  is  your  data  being  stored?  •  Contract  expiraBon,  bankruptcy,  theZ  •  Know  your  rights  before  you  sign  a  contract  

More  Bandwidth  •  Cloud  services  require  lots  of  bandwidth  •  Low  latency  key  for  certain  apps  •  QoS  can  help  with  contenBon,  not  oversubscripBon  

Disaster  Recovery  •  Cloud  data  is  sBll  not  invulnerable  •  Proper  DR/BC  planning  is  sBll  key  •  Check  contracts  for  outage  windows  and  SLAs

Do  Your  Homework  •  Cloud  requires  strategy,  not  a  forkliZ  •  Things  are  only  as  secure  as  you  build  them  to  be  •  There  is  no  “One  Size  Fits  All”  cloud  soluBon  •  Be  honest  with  yourself
