Serverless Computing (Dagstuhl Seminar 21201)

Authors: Cristina Abad, Ian T. Foster, Nikolas Herbst, and Alexandru Iosup

Published in: Dagstuhl Reports, Volume 11, Issue 4 (2021)

Abstract
In the backbone of our digital society, cloud computing enables an efficient, utility-like ecosystem of developing, composing, and providing software services. Responding to a trend to make cloud computing services more accessible, fine-grained, and affordable, serverless computing has gained rapid adoption in practice, and garnered much interest from both industry and academia. However successful, serverless computing manifests today the opportunities and challenges of emerging technology: a rapidly growing field but scattered vision, plenty of new technologies but no coherent approach to design solutions from them, many simple applications but no impressive advanced solution, the emergence of a cloud continuum (resources from datacenters to the edge) but no clear path to leverage it efficiently, and overall much need but also much technical complexity. Several related but disjoint fields, notably software and systems engineering, parallel and distributed systems, and system and performance analysis and modeling, aim to address these opportunities and challenges. Excellent collaboration between these fields in the next decade will be critical in establishing serverless computing as a viable technology. We organized this Dagstuhl seminar to bring together researchers, developers, and practitioners across disciplines in serverless computing, to develop a vision and detailed answers to the timely and relevant, open challenges related to the following topics: - Topic 1: design decisions for serverless systems, platforms, and ecosystems, - Topic 2: software engineering of serverless applications, but also systems, platforms, and ecosystems - Topic 3: applications and domain requirements for serverless computing, - Topic 4: evaluation of serverless solutions, and beyond (privacy, cyber-physical systems, etc.). In this document, we report on the outcomes of Dagstuhl Seminar 21201 "Serverless Computing" by integrating diverse views and synthesizing a shared vision for the next decade of serverless computing.

A dynamically adaptive, unstructured multicast overlay

Authors: Matei Ripeanu, Ian Foster, Adriana Iamnitchi, and Anne Rogers

Published in: Dagstuhl Seminar Proceedings, Volume 4411, Service Management and Self-Organization in IP-based Networks (2005)

Abstract
The simplicity of multicast as a communication primitive belies its broad utility as a building block for distributed applications. Nevertheless, creating and maintaining multicast structures can be challenging, particularly when networks are transient and/or dynamic. We introduce a new unstructured multi-source multicast (UMM) overlay approach that we argue is less complex than, but as efficient as, current state-of-the-art solutions based either on structured overlays or on running full routing protocols at the overlay level. UMM builds a base overlay independently from the routing mechanisms employed to route messages. On top of this base overlay, it selects distribution trees for each multicast source by first flooding the base overlay and then using the implicit information contained in duplicated messages to select and filter out redundant tunnels. Simple heuristics are used to maintain and evolve both the base overlay and the multicast distribution trees in response to changes in the set of overlay participants or in underlying network conditions. We experiment on a 65-node PlanetLab deployment and on ModelNet emulated distributed platforms to quantify the overheads associated with UMM operation and to explore its performance and adaptability to changes in the underlying network conditions.
