Multi-Tiered Bio-Inspired Self-Healing Architectural Paradigm for Software Systems

Self-healing capabilities have begun to emerge as an interesting and potentially valuable
property of software systems. Self-healing characteristic enables software systems to
continuously and dynamically monitor, diagnose, and adapt themselves after a failure
has occurred in their components. However, developing such a software system is a
significant challenge. Nature introduces to us exceptional concepts in terms of presenting
biological systems that have the ability to handle its abnormal conditions. Based on this
observation, this work presents a self-healing architecture for software system based on
one of the biological processes that have the ability to heal by itself- the wound-healing
process. The self-healing architecture provides software systems with the ability to
handle anomalous conditions that appear among the components. The presented
architecture is divided into two layers, functional layer and healing layer. To
demonstrate the functionality of the proposed self-healing software system, a formal
description of the architecture is presented.
