interoperability  points  of  contact  •  Collecting  ideas,  approaches  and  experience  as  

starting  point  for  a  new  Cloud  Interop  WG  •  Collaboration  with  other  organizations  •  Next  steps  

Agenda  

•  Interoperability  in  Cloud  Computing  is  of  increasing  importance.  Several  cloud  standards  have  emerged  in  recent  years  and  implementations  for  them  are  starting  to  show  up.    

•  Customers  and  providers  interested  in  using  the  standards  are  requiring  best-­‐practise  documents  for  using  or  implementing  the  different  standards  and  also  rely  on  information  how  they  can  combine  multiple  standards.  

Introduction  to  cloud  interoperability  

•  Several  different  Cloud  Standards  from  different  parties  are  existing  

•  Several  OGF  standards  currently  not  or  only  partly  ready  for  the  cloud  

•  A  consistent  OGF  Cloud  Portfolio  is  needed  •  strategies  for  combining  different  Cloud  Standards  /  

APIs  are  needed  •  existing  implementations  of  Cloud  APIs  need  to  get  

interoperable  •  Combined  Interoperability  Verification  Suites  need  to  be  

developed  •  People  need  to  be  brought  together  to  talk  about  issues  

in  specifications  and  implementations  

Overview  of  current  challenges  in  cloud  interoperability  

•  SNIA  –  Collaborative  organization  of  Plugfests  for  CDMI  &  OCCI  –  OCCI  and  CDMI  share  links  in  the  specification  –  SNIA  just  started  a  Cloud  Interoperability  group  targeted  at  Cloud  Storage  

•  ETSI  –  Interested  in  doing  interoperability  testing  for  Cloud  APIs  –  Offered  help  with  organizing  plugfests  and  coordinating  interoperability  

testing  •  CSCC  

–  End-­‐users  interested  in  the  adoption  of  Cloud  standards  •  DMTF  

–  Working  on  Cloud  standards  such  as  OVF  and  CIMI  –  Open  for  a  closer  collaboration  with  OGF  regarding  OCCI  and  CIMI  

•  NIST  –  NIST  Working  Definition  of  Cloud  Computing  –  Cloud  Computing  Use  Cases  

Collaboration  with  other  organizations  

•  SNIA  Cloud  Plugfest  targeting  OCCI  &  CDMI  –  Recently  organized  for  the  4th  time  –  Very  productive,  brings  together  developers  and  members  of  standardization  bodies  

–  >50  participants  from  all  around  the  world  –  Large  participation  by  companies  –  Can  be  easily  extended  to  incorporate  other  standards  

•  ETSI  Plugtests  –  Long  history  of  organizing  plugtests  for  Telecommunications  standards  

–  Developed  tools  for  documenting  the  standards  compliance  status  of  implementations  

Survey  of  existing  plug-­‐fests  and  other  interoperability  points  of  contact  

•  What  do  you  see  as  the  current  challenges?  •  What  should  a  Cloud  Interoperability  WG  target?  •  Who  should  be  involved?  How  can  we  reach  out?  •  Where  are  possible  overlaps  with  other  existing  

groups  from  within  OGF  or  from  other  standardization  bodies?  

•  What  do  you  understand  by  Cloud  Interoperability?    

Collecting  ideas,  approaches  and  experience  as  starting  point  for  a  new  Cloud  Interop  WG  

•  collect  use  cases  /  scenarios  •  landscape  of  existing  approaches  •  reference  and  document  existing  interoperability  efforts  •  Reference  /  create  definition  of  Cloud  Interoperability  •  create  cloud  interoperability  profile  /  profiles  for  Cloud  APIs  •  verify  passing  of  interoperability  profile  at  Plugfests  •  Check  with  other  OGF  WGs  to  identify  overlaps  •  Sync  up  with  other  standardization  bodies  •  Write  up  experience/best  practices  from  interoperability  

testing  •  Cloud  Interoperability  WG  creation?
