Abstract
Modern systems must be adaptable — to changing requirements, bug-fixes, new technologies and reconfiguration. For critical applications this must be possible at run-time; for complex applications it should be limitable to major sub-divisions of the system. The DRASTIC architecture addresses these goals by exploiting object persistence and distributed systems implementation techniques. It enables run-time changes of types, implementations, and the system configuration. This is based on a novel architectural abstraction of locality for evolution, called the ‘zone’. Contracts between zones automatically limit the visibility of such changes between zones. We present work in progress on DRASTIC's computational model and run-time system, illustrating support for software evolution and highlighting key features of our current implementation.
