Software systems dealing with distributed applications in changing environments normally
require human supervision to continue operation in all conditions. These (re-) configuring …

In the context of software development, models provide an abstract representation of a
software system or a part of it. In the software development process, they are primarily used …

Self-adaptation is typically realized using a control loop. One prominent approach for
organizing a control loop in self-adaptive systems is by means of four components that are …

To deal with the increasing complexity of software systems and uncertainty of their
environments, software engineers have turned to self-adaptivity. Self-adaptive systems are …

An elasticity policy governs how and when resources (eg, application server instances at the
PaaS layer) are added to and/or removed from a cloud environment. The elasticity policy …

To update a performance model, its parameter values must be updated, and in some
applications (such as autonomic systems) tracked continuously over time. Direct …

Computing systems are becoming more and more dynamically reconfigurable or adaptive,
to be flexible wrt their environment and to automate their administration. Autonomic …

Self-adaptive systems research is expanding as systems professionals recognize the
importance of automation for managing the growing complexity, scale, and scope of …

Adaptive systems respond to changes in their internal state or external environment with
guidance from an underlying control system. ULS systems are particularly likely to require …

In this paper, we present a method for performance testing of transactional systems. The
methods models the system under test, finds the software and hardware bottlenecks and …
