Resilience in Dynamic Component-Based Applications

Abstract

Increasingly, software is required to accommodate new features after the design and deployment stages. Applications are designed to improve their adaptability and flexibility. Software needs to evolve at runtime with minimal interruptions and, when possible, never stop running. Different motivations push software design to allow such evolution at runtime. For example, production systems with critical availability requirements need to be updated with little perceived execution interruption. This paper enumerates challenges in the construction of dynamic component-based applications that are capable of undergoing changes during execution, with minimal impact.
