Workshop on Adaptable Cloud Architectures - WACA @ DisCoTec - 2nd Call for Papers
by Giuseppe De Palma 24 Mar '25

24 Mar '25

Workshop on Adaptable Cloud Architectures (WACA) Co-located with DisCoTec 2025 June 20, 2025 - Lille, France The Workshop on Adaptable Cloud Architectures (WACA) is soliciting the submission of contributions on Cloud architecture adaptation. WACA aims to bring together researchers and practitioners to explore and compare different approaches to architectural adaptation in Cloud systems. The workshop focuses on adaptive strategies that extend beyond traditional scaling mechanisms, investigating architectural modifications in response to: - evolving user requirements; - service load fluctuations (including both legitimate traffic increases and security threats); - infrastructure failures (machine outages, external service disruptions, etc.). To facilitate meaningful comparisons between different approaches, we provide a reference case study based on an adaptable version of TeaStore. This common ground enables participants to demonstrate their methods and technologies in a comparable environment. We invite submissions addressing, but not limited to: - Modeling approaches for adaptive Cloud architectures - Implementation techniques for adaptation mechanisms - Runtime verification of adaptation properties - Performance analysis of adaptation strategies - Security considerations in architectural adaptation - Tools and frameworks supporting Cloud architecture adaptation Papers should present contributions related to the workshop themes, preferably demonstrated through the provided case study scenarios. We strongly encourage submissions to include supporting artifacts that complement the paper's contributions. Detailed submission instructions are available on the workshop website https://waca-ws.github.io/2025 The workshop itself does not have proceedings, but we will invite contributors to refine their work for the publication of the workshop post-proceedings that will be published in Electronic Proceedings in Theoretical Computer Science (EPTCS).
