PESOS 2010 provided a forum for presenting and discussing current work and research topics related to serviceoriented systems. The workshop had keynotes on SOA testing challenges and adaptive service-oriented systems. There were four paper sessions on the topics of service development, testing and evolution of service-oriented systems, service adaptation, and quality of service (QoS) and Service-Level Agreements (SLAs) in service-oriented environments. General discussions focused on these overall themes. These discussions resulted in the identification of research challenges for the future.</jats:p>
