Transcript of "Rishidot Research Briefing Note - AppZero"

  1. 1. AppZero    A  Briefing  Note  By  Lori  Macvittie   AppZero   A  Briefing  Note  by  Lori  Macvittie     Company:     AppZero  (www.appzero.com)   Market:     Application  Migration     Products:     AppZero  Cloud   Summary:     AppZero  focuses  on  enabling  application  migration  in  inter-­‐IaaS   scenarios.  Its  zapp  migration  technique  focuses  on  m igration  at  the   application  layer  rather  than  at  the  virtual  m achine  layer  as  per  most   alternative  solutions.     AppZero  technology  is  designed  to  manage  migration  of  applications   in  federated  cloud  environments  as  well  as  on-­‐boarding  enterprise   applications  to  public  cloud  computing  environments    
  2. 2. AppZero    A  Briefing  Note  By  Lori  Macvittie   Market  Overview     The  market  for  Application  Migration  is  just  beginning  to  emerge  into  an  evolving  state  as  cloud   adoption  of  packaged  applications  becomes  a  key  focus  for  enterprise  customers.     There  are  two  primary  approaches  to  migration  of  existing  applications  with  varying  technology   approaches  to  achieving  migration:     1. Virtual  Machine  migration     a. Wholesale  VM  migration     b. Shim-­‐based  migration     2. Application  migration     a. SI  /  manual  migration     b. Toolsets   c. Standards     The  market  is  dominated  by  wholesale  VM  migration  methods  as  it  remains  the  least  complex.   Application  migration  via  toolsets  is  gaining  mindshare  due  to  its  ability  to  transcend  not  only  cloud   environments  but  hypervisor  dependencies,  allowing  a  wider  selection  of  and  greater  mobility  between   providers.     SI  and  manual  migration  has  been  the  primary  mechanism  through  which  non-­‐native,  existing   applications  are  moved  from  enterprise  to  cloud  due  to  incompatible  hypervisor  foundations  as  well  as   requirements  in  some  cases  to  adapt  existing  applications  to  a  cloud  environment.     Standards  are,  at  this  juncture,  non-­‐existent  with  the  exception  of  OASIS  CAMP  (Cloud  Application   Management  for  Platforms)  which  has  only  recently  been  proposed  for  consideration.  Though  its   supporters  are  non-­‐trivial,  it  remains  to  be  seen  whether  the  specification  will  survive  the  standards   process  or  whether  a  niche-­‐filling  technology  will  fill  the  hole  it  is  designed  to  address  in  the  interim.   AppZero  Overview     AppZero  has  chosen  to  focus  on  migration  of  applications  irrespective  of  hypervisor  foundations.  Its   technology  is  able  to  selectively  migrate  processes  and  daemons  for  an  application  from  one  IaaS   environment  to  another.  This  process  is  manual  and  requires  knowledge  specific  to  the  application  to   ensure  all  dependent  processes  are  included.     Migration  is  currently  limited  to  migration  between  similar  operating  systems  and  specifically  excludes   support  for  Microsoft  SharePoint  and  Exchange.  Migration  further  requires  shutdown  of  the  application   which  disallows  live  migration,  eliminating  the  possibility  of  leveraging  the  tool  for  just-­‐in-­‐time  cloud   bursting  architectures.     The  wrapper  used  by  AppZero  to  migrate  the  application  can  be  dissolved  upon  successful  migration,   ensuring  no  reliance  on  shims  or  agents  post-­‐migration.    
  3. 3. AppZero    A  Briefing  Note  By  Lori  Macvittie     Advantages     -­‐ Requires  less  bandwidth  than  inter-­‐environment  virtual  machine  migration   -­‐ Immune  to  latency-­‐based  restrictions  on  virtual  machine  migration     -­‐ Non-­‐disruptive  to  existing  architecture     -­‐ Time  to  migrate  reduce  to  minutes  instead  of  hours  or  days     Disadvantages       -­‐ Potential  for  boomeranging  infected  /  hijacked  processes     -­‐ Restriction  on  inter-­‐OS  migration  eliminates  ability  to  migrate  aging  OS-­‐dependent   applications  off-­‐premise     -­‐ Reliance  on  manual  selection  of  appropriate  processes  /  daemons  introduces  potential  for   mistakes     Summary     AppZero’s  approach  is  relatively  unique  within  the  broader  Application  Migration  market  and  brings   with  it  promising  opportunities  for  customers  to  realize  a  federated  cloud  ecosystem  as  well  as  enabling   pre-­‐positioning  of  applications  in  public  cloud  environments  in  support  of  seasonable  elasticity   requirements.
