In the last years, we experienced a continuous evolution of software architectures. Monolithic systems, n-tier architectures, Service-Oriented architectures, and lately serverless microservices revolutionized system design. Practitioners are keeping on following new trends, including those related to software architectures.

It is interesting to see that in 2014, after the introduction of Microservices, a large number of companies invested a significant amount of effort in migrating their systems to microservices. However, in the fall of 2018, the largest practitioners’ conferences (QCon 2018 London, O’Reilly Software Architecture Conference 2018 - London, AWS Re-Invent 2018) started to push practitioners to shift towards pure serverless applications, often mentioning that the migration to microservices was a mistake. The saga continued in 2020 when the same practitioners’ conferences, practitioners started to recommend a hybrid solution, shifting to serverless microservices. Lately, Google introduced the concept of the ”Modular Monolith” with ”Service Weaver” enabling developers to write applications as a modular monolith and deploy them as a set of microservices.

One of the reasons leading companies to migrate to new architectures is the hype. Companies often migrate because they expect to achieve important benefits, overcoming some major issues. However, this is not always the case, and often the expected benefits are not enough to justify the migration costs.

The above example is just one instance among many, driven by new technologies and their associated promises, that disrupt traditional architectures. It underscores the importance of mastering software-intensive system architecture, not only with a focus on microservices but also in consideration of emerging trends. Other notable examples encompass the impact of the AI mega-trend and Machine Learning (ML) on architectural decisions, the necessity to address sustainability goals and associated concerns at the architectural level, the increasing demand for extreme flexibility and adaptability in all industry sectors due to the prevalence of software-intensive systems resulting from the digital transformation of modern society, and the architectural implications stemming from the application of DevOps and its various specializations.

Within this workshop, our objective is to create a platform for practitioners to share their experiences and for researchers to present their findings regarding these trends. We aim to facilitate a valuable exchange of opinions, mutual learning, and the advancement of the state of the art in adopting these new architectural trends.

Call for Papers

2nd International Workshop on New Trends in Software Architecture (SATrends2025)

In this workshop, we aim to establish a forum to collect experiences, including failures and success stories, enabling practitioners and researchers to exchange opinions, learn from each other, and progress the state of the art in software architectures. Given the goals of the workshop, we are not interested in specific technical submissions, but we are looking for papers including (but not limited to):

• Industrial Experience Reports.
• Position Papers.
• Extended Abstracts.

All contributions will undergo a thorough peer review by three program committee members. Accepted papers will be included in the IEEE workshop proceedings.

A selection of SATrends2024 papers will be considered for extension and submission to the ICSA 2024 NEMI track

Program

09:00- 09:15 Opening

9:15 - 09:45 SATRENDS-1-Keynote: Matrushka and the spider - or the challenge to connect architectural knowledge across boundaries.

(Chair: Davide Taibi)

Abstract

Architectural knowledge management emerged in the mid-2000s as a way to address the ‘why’ behind architecture designs. Since then, the field has seen many developments but all typically focus on (the knowledge of) a single architecture model. This is, however, an artificial boundary.

Matrushka and the spider are two creatures that habitually cross this boundary, and force us to cross it too. Matrushka challenges our understanding of what the scope of a ‘software intensive system’ is. The spider weaves a web in which everything becomes more and more connected - entangled, perhaps.

This talk addresses insights from industry and challenges for practitioners and researchers who are looking to connect architectural knowledge across the boundary of architecture in isolation.

Dr. Remco de Boer is a partner at ArchiXL, a Dutch enterprise & information architecture consultancy, where he leads the development of their semantic knowledge management platform. He is a Research Fellow in Digital Architecture at the Vrije Universiteit Amsterdam, where he also lectures the Digital Architecture course. As a practicing architect, he is involved in the design and evolution of national reference architectures for education and cultural heritage. His interests include the use of semantic technologies to integrate and link knowledge sources to support knowledge management. His ideas on architectural knowledge management have had a significant impact on the way in which the Dutch public sector and other organizations now treat their architectural knowledge.

16:00-16:30 SATRENDS-2-Keynote: Playing with Abstractions: Can LLMs be Architects New Best Friend? (by Karthik Vaidhyanathan)

(Chair: Henry Muccini)

Abstract

Text is a powerful abstraction of reality, like architecture abstracts complex software systems. The advent of Large Language Models (LLMs) has set new benchmarks in understanding and generating human-like text, revolutionizing multiple sectors. In this talk, we explore some of these capabilities of LLMs to understand whether LLMs can be architects new best friend. Beginning with an overview and background of LLMs, we delve into their capabilities in generating design decisions, thereby contributing to better knowledge management. We further discuss how we are leveraging LLMs capabilities for runtime self-adaptation and conclude by showcasing our recent efforts in developing a Generative AI powered autonomous CloudOps Copilot.
