This volume of the Lecture Notes in Computer Science series contains all papers accepted for presentation at the 19th IFIP/IEEE International Workshop on Distributed Systems: Operations and Management (DSOM 2008),which was held September 25-26, 2008 on the island of Samos, Greece. DSOM 2008 was the 19th event in a series of annual workshops. It followed in the footsteps of previous s- cessful meetings, the most recent of which were held in San Josó e, California, USA (DSOM 2007), Dublin, Ireland (DSOM 2006), Barcelona, Spain (DSOM 2005), Davis, California, USA (DSOM 2004), Heidelberg, Germany (DSOM 2003), and Montreal, Canada (DSOM 2002). The goal of the DSOM workshops is to bring together researchers from industry and academia working in the areas of n- works, systems, and service management, to discuss recent advances and foster future growth. In contrast to the larger management conferences, such as IM (Integrated Network Management) and NOMS (Network Operations and M- agement Symposium), DSOM workshops have a single-track program in order to stimulate more intense interaction among participants. The theme of DSOM 2008 was ǣManaging Large-Scale Service Deploymentǥ focusing both on management of overlay networks and on virtualized service - frastructures. The concepts of abstract overlays and virtualization constitute key contributors for e?cient large-scale service deployment and testing. Scalable - stract overlay networks accompanied with appropriate management techniques o?er ?exibility for future service deployment and consumption with high qu- ity of experience.
