       Most  of  the  software  tools  created  so  far  to aid in the
       construction  of  distributed  applications  addressed  how  to 
       replicate  data  consistently  in the presence of failures, but
       without  offering  much  relief  for  the problem of building a
       dependable  and  long-running application. This paper describes
       our   experience   building  Treplica,  a  replication  toolkit 
       offering application developers a very simple programming model
       based  on  an  object-oriented specification for replication of
       durable  applications.  Treplica  simplifies the development of
       high-available   applications   by   making   transparent   the  
       complexities  of  dealing  with  replication  of data that must
       survive  process crashes and recoveries. These complexities are
       not  negligible,  and we believe we have found a compelling way
       to   address   this   problem  under  a  simple  to  understand 
       object-oriented  interface.  We have used Treplica successfully
       to  add  fault  tolerance  to  a  implementation  of  the TPC-W
       benchmark  and  we have obtained very good performance, even in
       the presence of failures.
