*** Last Call for Workshop Papers *** 19th European Conference on Software Architecture (ECSA 2025) September 15-19, 2025, 5* St. Raphael Resort and Marina, Limassol, Cyprus https://conf.researchr.org/home/ecsa-2025 (*** Proceedings to be published by Springer in LNCS ***) The European Conference on Software Architecture (ECSA) is the premier European forum for presenting and discussing software architecture research and practice. ECSA edition 2025 hosts workshops on topics related to software architecture. The following workshops will be held between September 15-16, 2025: 8th International Workshop on Context-Aware, Autonomous and Smart Architectures (CASA) https://casaecsa.github.io/casa2025/ Software is becoming increasingly aware of its current execution context. Decisions that were traditionally made at design time are being postponed until runtime to improve the services that software provides to its users. In addition, software reasons about the execution environments and its internal state to improve the functionality provided to its users. Some of the keywords that characterize software today are: context-aware, dynamic, autonomous, smart, adaptive, self-managed. In this context, the Context-aware, Autonomous, and Smart Architectures (CASA) workshop aims to address the issues and challenges raised by the design, implementation, and evaluation of software systems characterized by the above keywords. Novel design and development approaches are needed to address the new issues raised by such systems. New solutions are expected to properly address the trade-offs between the various quality attributes that characterize these systems. Or, existing architectural solutions should be adapted and improved to meet the evolving and dynamic requirements of context-aware, autonomous, and intelligent systems. The workshop aims to bring together software engineers, computer scientists, researchers, practitioners, and educators to discuss and exchange results, case studies, experiences, novel approaches, and visionary ideas on software architectures for context-aware, autonomous, and smart solutions. 1st International Workshop on Architecting Digital Twin of an Organization (ArchDTO) https://archdto.github.io/archdto2025/ The Digital Twin of an Organization (DTO) extends the concept of Digital Twins to create virtual replicas of business models, processes, resources, and interactions. DTOs enable optimization of decision-making, increased efficiency, and adaptability to rapid changes by leveraging real- time data, simulations, AI, and predictive analytics. Despite their transformative potential, DTOs are still in early development, facing significant software architecture challenges such as scalability, interoperability, model robustness, and real-time data integration. This workshop explores the architectural frameworks, design patterns, and software engineering principles needed to build robust DTOs. Topics include frameworks for DTO creation, enterprise modeling methodologies, technological enablers like AI and the Internet of Things, and real-world use cases from academia and industry. Given the novelty of the topic, the workshop consists of two main sessions: (1) presentations of academic and industry papers on DTO architectures, frameworks, and technologies, and (2) an interactive workshop session, where participants will engage in problem-solving, explore case studies, and collaboratively define challenges, solutions, and best practices for architecting DTOs. 1st International Workshop on AI-Assisted Software Architecting (AISA) https://sites.google.com/view/aisasa/home?pli=1 AI-assisted software architecting is transforming how architectural decisions are made, implemented, and maintained. Leveraging artificial intelligence, this paradigm enhances architectural decision making, automates repetitive architecting tasks, and optimizes system designs. The AISA workshop aims to bring together researchers and practitioners to explore AI’s role in various software architecting activities, including architecture analysis, design, decision-making, evolution, and documentation. We will also discuss AI-driven architectural pattern recommendations, best practices, and the application of AI in continuous architecting and self-adaptive architectures. Topics include AI-assisted architecture synthesis, automated architecture pattern selection, refactoring, security enforcement, and integrating AI into DevOps and MLOps pipelines. The workshop will foster discussions and collaborations between academia and industry to identify open challenges, research directions, and practical applications 5th International Workshop on Agility with Microservices Programming (AMP) https://amp-workshops.github.io The AMP workshop aims to collect experiences on microservice adoption and reporting best practices, as well as failure cases, to build community knowledge based on past mistakes and successes. We also emphasize the current trend towards AI-driven software engineering practices and the development of data- intensive applications. The workshop seeks for solutions and experiences both on both AI-assisted tooling, and building data-intensive applications and LLMs using microservices. The workshop is open to experience reports from practitioners and academics. We seek to collect original work on the science and engineering of programming microservices. 1st International Workshop on Software Architecture for Data-Intensive Systems (SADIS) https://sadis2025.smartarch.cz Modern software systems increasingly rely on data-centric processes to fuel intelligent features, scalable services, and real-time insights. As these systems evolve, designing effective software architectures for data-intensive environments becomes critical yet challenging. These architectures must address complex concerns such as handling high-velocity data streams, ensuring security and privacy, integrating heterogeneous data sources and heterogeneous computation fabrics (including GPUs/TPUs and edge devices), and adapting to changing workloads. The workshop aims to bring together academic researchers, industry practitioners, and thought leaders to explore cutting-edge approaches for building, deploying, and maintaining robust data-centric solutions. We invite discussions on a range of topics at the intersection of data-intensive systems and software architecture, including machine learning (ML) pipelines, ML Operations (MLOps) frameworks and patterns, domain-specific languages, reference architectures, and visualization techniques. Emphasis is placed on practical experiences, innovative tools and platforms, and theoretical advancements that tackle the ever-growing demands placed on data-intensive systems. By fostering interdisciplinary collaboration and knowledge exchange, the workshop seeks to shape the future of data-driven architecture design and empower professionals and researchers to address emerging challenges in this rapidly evolving domain. Workshop on Adaptive and Reconfigurable Systems and Architectures (AROSA) https://www.redcad.org/events/arosa2025/ The goal of this workshop is to bring together researchers and practitioners both from the Academia and from the Industry working in the areas of the adaptation and reconfiguration of distributed systems. Different investigation topics are involved, such as: CBSE, Web service, cloud applications, mobile applications, Functional and Non-Functional requirements (QoS, performance, resilience), monitoring, diagnosis, deci- sion and execution of adaptation and reconfiguration. Different research areas are covered: concepts, methods, techniques, and tools to design, develop, deploy and manage adaptive and reconfigurable software systems. The concept of adaptive and reconfigurable software systems has been introduced in order to describe architectures, which exhibit such properties. An adaptive and reconfigurable software system can repair itself if any execution problems occur, in order to successfully complete its own execution, while respecting functional requirements and quality attributes. In the design of an adaptive and reconfigurable software system, several aspects have to be considered. For instance, the system should be able to predict or to detect degradations and failures as soon as possible and to enact suitable recovery actions.
