An Architectural Approach to Replication Configuration

Replication is a traditional means for guaranteeing service availability in the distributed computing domain. However, existing solutions manage the inherent replication and consistency complexity by limiting the problem to the specific needs of a given application domain and of a given execution environment. The approach has two major drawbacks : (i) replication solutions are most challenging to reuse and (ii) applications cannot be deployed in different execution environments (with different replication and consistency requirements) without major changes to their structure and code
