With the exponential growth of communication and information technologies, adaptation has
gained a significant attention as it becomes a key feature of service-based systems, allowing …

It is a well-known problem that intrusion detection systems overload their human operators
by triggering thousands of alarms per day. As a matter of fact, IBM Research's Zurich …

Fine-grained elasticity control of cloud services has to deal with multiple elasticity
perspectives (quality, cost, and resources). We propose a cloud services elasticity control …

Due to the growing pervasiveness of the service paradigm, modern systems are now often
built as software as a service, and tend to exploit underlying platforms and virtualized …

The transition to cloud computing offers a large number of benefits, such as lower capital
costs and a highly agile environment. Yet, the development of software engineering …

Abstract [Context] Complex and heterogeneous software systems need to be monitored as
their full behavior often only emerges at runtime, eg, when interacting with other systems or …

The identification of services during the execution of service-based applications to replace
services in them that are no longer available and/or fail to satisfy certain requirements is an …

The Cloud offers enhanced flexibility in the management of resources for any kind of
application while it promises the reduction of its cost as well as its infinite scalability. In this …

When operating in volatile environments, service-based systems (SBSs) that are
dynamically composed from component services must be monitored in order to guarantee …

Abstract Context and motivation Service-Based Systems are highly dynamic software
systems composed of several web services. In contrast to other types of systems, Service …
