self-organizing algorithms, adaptive service placement, distributed systems, grid systems In this paper we consider distributed computing systems which exhibit dynamism due to their scale or inherent design, e.g. inclusion of mobile components. Prominent examples are Grids-large networks where computing resources can transparently be shared and utilized for(More)
The paper discusses a framework and advanced technologies enabling the quantitative analysis, organization and optimization of large-scale, globally distributed enterprise and e-service systems. The goal is to organize complex systems in such ways that traffic at application and service layers can be better explained, predicted and controlled. In(More)
An automated service demand–supply control system can improve a large-scale grid infrastructure comprising a federation of distributed utility data centers. T he growing complexity of large-scale systems raises concerns about their effectiveness and man-ageability. New approaches to system design, use, and management address these concerns through the(More)
grid computing, utility computing, utility data center, control architecture, virtual data center Growing complexity and cost of system deployment, ownership and operation pushes to look for economical, yet limitless ways to organize and manage large-scale computing in science, technology and businesses. The two most prominent examples are the concepts of(More)
The explosion in globally connected devices, computers, and services ultimately evolves into very large-scale, inter-connected systems approaching a new era of planetary-scale computing. The backbone of planetary-scale computing is a global network of data centers. The paper provides an overview of research at HP Laboratories exploring new approaches under(More)
The report describes a modeling library for analysis and optimization of distributed service systems: enterprise computing infrastructures, E-commerce and E-service systems. The library uses a small number of basic notions, such as service, server, cluster (of servers), clients and message, which allow us to describe, analyze and optimize various s ystem(More)
virtual data center, management system, management agent, control system, deployment The starting point for this work was: What would be the implications when systems and with them their management systems would become two orders of magnitude larger then they are today? We focus on one problem: How management agents can be automatically deployed in massive(More)
