Abstract
| Why is it so difficult to build self-adaptive systems by reusing existing
self-adaptation services and frameworks? In this paper, we
argue that one possible explanation is that there is a fundamental
mismatch between the adaptation needs of modern software
systems, and the architectural models and adaptation mechanisms
supported by current self-adaptation solutions. We identify and
discuss the main reasons leading to this problem by looking into a
number of representative self-adaptation solutions that have been
proposed in recent years, including open source frameworks and
cloud-based services, from two perspectives: generality, i.e., their
ability to support a variety of architectural models and adaptation
mechanisms, and reusability, i.e., their ability to be reused without
requiring substantial effort from software developers. We then make
the case that recent industry progress toward microservices and
their enabling technologies can open the way to the development
of more general and reusable self-adaptation solutions. |
