A Control-Theoretic Approach to Self-adaptive Systems and an Application to Cloud-Based Software

Software systems are usually developed to provide a fixed set of functionalities within given environmental conditions. However, in the last few years, there has been an increasing interest in systems that can autonomously modify their behavior in response to dynamic changes occurring in their execution environment. In one word, they must be self-adaptive. Self-adaptation requires the ability to discover and analyze changes, and to react by …
