Custom Serverless Function Scheduling Policies: An APP Tutorial

Authors: Giuseppe De Palma, Saverio Giallorenzo, Jacopo Mauro, Matteo Trentin, and Gianluigi Zavattaro

Published in: OASIcs, Volume 111, Joint Post-proceedings of the Third and Fourth International Conference on Microservices (Microservices 2020/2022)

Abstract
State-of-the-art serverless platforms use hard-coded scheduling policies that hardly accommodate users in implementing functional or performance-related scheduling logic of their functions, e.g., preserving the execution of critical functions within some geographical boundaries or minimising data-access latencies. We addressed this problem by introducing {APP}: a declarative language for defining per-function scheduling policies which we also implemented as an extension of the open-source OpenWhisk serverless platform. Here, we present a gentle introduction to {APP} through an illustrative application developed over several incremental steps.

A Sound Algorithm for Asynchronous Session Subtyping

Authors: Mario Bravetti, Marco Carbone, Julien Lange, Nobuko Yoshida, and Gianluigi Zavattaro

Published in: LIPIcs, Volume 140, 30th International Conference on Concurrency Theory (CONCUR 2019)

Abstract
Session types, types for structuring communication between endpoints in distributed systems, are recently being integrated into mainstream programming languages. In practice, a very important notion for dealing with such types is that of subtyping, since it allows for typing larger classes of system, where a program has not precisely the expected behavior but a similar one. Unfortunately, recent work has shown that subtyping for session types in an asynchronous setting is undecidable. To cope with this negative result, the only approaches we are aware of either restrict the syntax of session types or limit communication (by considering forms of bounded asynchrony). Both approaches are too restrictive in practice, hence we proceed differently by presenting an algorithm for checking subtyping which is sound, but not complete (in some cases it terminates without returning a decisive verdict). The algorithm is based on a tree representation of the coinductive definition of asynchronous subtyping; this tree could be infinite, and the algorithm checks for the presence of finite witnesses of infinite successful subtrees. Furthermore, we provide a tool that implements our algorithm and we apply it to many examples that cannot be managed with the previous approaches.

Automatic Application Deployment in the Cloud: from Practice to Theory and Back (Invited Paper)

Authors: Roberto Di Cosmo, Michael Lienhardt, Jacopo Mauro, Stefano Zacchiroli, Gianluigi Zavattaro, and Jakub Zwolakowski

Published in: LIPIcs, Volume 42, 26th International Conference on Concurrency Theory (CONCUR 2015)

Abstract
The problem of deploying a complex software application has been formally investigated in previous work by means of the abstract component model named Aeolus. As the problem turned out to be undecidable, simplified versions of the model were investigated in which decidability was restored by introducing limitations on the ways components are described. In this paper, we take an opposite approach, and investigate the possibility to address a relaxed version of the deployment problem without limiting the expressiveness of the component model. We identify three problems to be solved in sequence: (i) the verification of the existence of a final configuration in which all the constraints imposed by the single components are satisfied, (ii) the generation of a concrete configuration satisfying such constraints, and (iii) the synthesis of a plan to reach such a configuration possibly going through intermediary configurations that violate the non-functional constraints.

On the Complexity of Parameterized Reachability in Reconfigurable Broadcast Networks

Authors: Giorgio Delzanno, Arnaud Sangnier, Riccardo Traverso, and Gianluigi Zavattaro

Published in: LIPIcs, Volume 18, IARCS Annual Conference on Foundations of Software Technology and Theoretical Computer Science (FSTTCS 2012)

Abstract
We investigate the impact of dynamic topology reconfiguration on the complexity of verification problems for models of protocols with broadcast communication. We first consider reachability of a configuration with a given set of control states and show that parameterized verification is decidable with polynomial time complexity. We then move to richer queries and show how the complexity changes when considering properties with negation or cardinality constraints.
