Modern software applications are subject to uncertain operating conditions, such as
dynamics in the availability of services and variations of system goals. Consequently …

Software cybernetics explores the interplay between software and control and is motivated
by the fundamental question whether or not and how software behavior can be controlled. In …

Sensor networks can be considered distributed computing platforms with many severe
constraints, including limited CPU speed, memory size, power, and bandwidth. Individual …

Power control is becoming a key challenge for effectively operating a modern data center. In
addition to reducing operation costs, precisely controlling power consumption is an essential …

Control engineering approaches have been identified as a promising tool to integrate self-
adaptive capabilities into software systems. Introduction of the feedback loop and controller …

This paper presents the design and implementation of an adaptive Web server architecture
to provide relative and absolute connection delay guarantees for different service classes …

Today's data centers face two critical challenges. First, various customers need to be
assured by meeting their required service-level agreements such as response time and …

An increasing number of distributed real-time systems face the critical challenge of providing
quality of service guarantees in open and unpredictable environments. In particular, such …

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 …

Feedback mechanisms can help today's increasingly complex computer systems adapt to
changes in workloads or operating conditions. Control theory offers a principled way for …
