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 Jos 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 "Managing Large-Scale Service Deployment" 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.

The International Conference on Autonomous Infrastructure, Management and Se- rity (AIMS 2010) was a single-track event integrating regular conference paper s- sions, tutorials, keynotes, and a PhD student workshop into a highly interactive event. The main goal of AIMS is to look beyond borders and to stimulate the exchange of ideas across different communities and among PhD students. AIMS 2010 collocated the International Summer School in Network and Service Management (ISSNSM 2010). This unique summer school offers hands-on learning experiences in network and service management topics, which requires attendees to work in practical on-site courses combined with preceding short tutorial-like teaching sessions. AIMS 2010--which took place during June 23-25, 2010, in Zurich, Switzerland and was hosted by the Communication Systems Group CSG, Department of Inform- ics IFI, of the University of Zurich UZH--followed the already established tradition of an unusually vivid and interactive conference series in terms of the fourth conf- ence, after successful instantiations in Oslo, Norway 2007, Bremen, Germany 2008, and Enschede, The Netherlands 2009. AIMS 2010 focused especially on autonomous management aspects of modern networks and their services. The set of mechanisms, peer-to-peer-based schemes, scalability aspects, and autonomous approaches are of major interest. In particular the design, monitoring, management, and protection of networked systems in an efficient, secure, and autonomic manner are key to comm- cially viable and successful networks and services.
