We are glad to announce that the 7th edition of the workshop on Principles of Engineering Service-Oriented and Cloud Systems (PESOS 2015) will be collocated with the 37th International Conference on Software Engineering (ICSE 2015), Florence, Italy.

The theme of PESOS is: Principles and Practices for Engineering Collaborative Services in the Cloud.

This will be the 7th edition of PESOS that has become a regular feature at ICSE as a collocated workshop that brings together software engineering researchers and practitioners working in the areas of service-oriented systems to discuss research challenges, new developments and applications, as well as methods, techniques, experiences, and tools to support engineering, evolution and adaptation of service-oriented systems. The technical program for PESOS 2015 has been finalised and here are the titles, authors and briefs about the accepted papers.

The paper “A Pattern-Based Formalization of Cloud-Based Elastic Systems” by Dustdar et. al. is focused on proposing a solution to the elasticity challenges of Cloud-based systems to accommodate the dynamically changing demands of the resources based on fluctuating workloads.

The paper “Architectural Runtime Models for Privacy Checks of Cloud Applications” by Schmieders et. al. highlights the privacy related issues in cloud computing and proposes a solution for ensuring the compliance of data movements in cloud with the privacy policies by exploiting runtime models for the analysis of privacy violations during runtime.

The paper “Continuous Evolution of Multi-tenant SaaS Applications: A Customizable Dynamic Adaptation Approach” by Gey et. al. reports the research aimed at studying the challenges of evolving multi-tenant SaaS application without impacting their service continuity. The paper reports a solution that describes the key requirements of gradual upgrades of a SaaS application for each tenant without violating any Service Level Agreement (SLA) with the tenants.

The paper “Enabling Collaborative Development in an OpenStack Testbed: the CloudWave Use Case” by Bruneo et. al. reports the challenges of a project, CloudWave, that purports to develop and evaluate a DevOps ready testbed environment that can support the development of software components to be integrated into a single multi-layer Cloud stack based on OpenStack. The project aims to have a DevOps ready testbed environment that would allow the project partners to exert full control over the deployed  componentry and collaborate on the development tasks. The paper reports the project’s goals and the current state of the progress made.

The paper “An Architecture for Self-reconfiguration of Convergent Telecom Processes” by Ordóñez et. al. describes the challenges of servicing being failed during execution without having any robust mechanism for recovering the failed telecommunication services automatically to a level of normal execution. The authors report an iterative algorithm and its implementation for efficiently repairing the convergent processes in telecom environments.
