Khazana: An infrastructure for building distributed services

Essentially all distributed systems, applications, and services at some level boil down to the problem of managing distributed shared state, Unfortunately, while the problem of managing distributed shared state Is shared by many applications, there is no common means of managing the data - every application devises ifs own solution. We have developed Khazana, a distributed service exporting the abstraction of a distribution persistent globally shared store that applications can else to store their shared slate. Khazana is responsible for performing many of the common operations needed by distributed applications, including application; consistency management, fault recovery, access control, and location management. Using Khazana as a form si middleware, distributed applications con be quickly developed from corresponding uniprocessor applications through the insertion of Khazana data access and synchronization operations.
