Abstract
Self-management is a key feature of autonomic systems. This often
demands the dynamic reconfiguration of a distributed application. An
important issue in the reconfiguration process is the strategy that is
used to coordinate the multiple participants involved in the
reconfiguration. This paper addresses the problem of providing support
for multiple reconfiguration strategies in autonomic systems that are
designed as self-reconfigurable service compositions. We decompose
existing strategies in two separate aspects --- an orchestration
protocol and a local reconfiguration procedure. This separation
allowed us to design a set of generic pluggable components that can be
integrated in concrete service compositions, in order to support
different strategies. The strategy selection is performed according to
the semantics of each reconfiguration. To illustrate our approach, we
have implemented an instance of these pluggable components for the
RAppia composition framework.
