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.

Big Graph Processing Systems (Dagstuhl Seminar 19491)

Authors: Angela Bonifati, Alexandru Iosup, Sherif Sakr, and Hannes Voigt

Published in: Dagstuhl Reports, Volume 9, Issue 12 (2020)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 19491 "Big Graph Processing Systems". We are just beginning to understand the role graph processing could play in our society. Data is not just getting bigger, but, crucially, also more connected. Exploring, describing, predicting, and explaining real- and digital-world phenomena is increasingly relying on abstractions that can express interconnectedness. Graphs are such an abstraction. They can model naturally the complex relationships, interactions, and interdependencies between objects. However, after initial success, graph processing systems are struggling to cope with the new scale, diversity, and other real-world needs. The Dagstuhl Seminar 19491 aims to addresses the question: How could the next decade look like for graph processing systems? To identify the opportunities and challenges of graph processing systems over the next decade, we met in December 2019 with circa 40 high-quality and diverse researchers for the Dagstuhl Seminar on Big Graph Processing Systems. A main strength of this seminar is the combination of the data management and large-scale systems communities. The seminar was successful, and addressed in particular topics around graph processing systems: ecosystems, abstractions and other fundamental theory, and performance.
