a Logical Architecture design method for microservices Architectures
European Conference on Software Architecture, 2019Co-Authors: N C Santos, Ricardo J. Machado, Francisco Morais, Carlos E Salgado, Monica Melo, Sara Silva, Raquel Martins, Marco Pereira, Helena Rodrigues, Nuno FerreiraAbstract:The use of microservices Architectures has been widely adopted in software development, especially for cloud-based solutions. Developing such solutions faces several challenges beyond typical Architecture and service design concerns, including service exposition (API), inter-service communication, and infrastructure deployment, among others. Although model-driven approaches allow abstracting microservices behavior from the business domain, there is a lack of proper methods for addressing the referred challenges. In this paper, the elicitation of microservices, their identification uses using functionally decomposed UML use cases as input within a Logical Architecture derivation method, namely an adapted version of the Four Step Rule Set (4SRS), using SoaML diagrams, that responds to microservices specific characteristics. We demonstrate the approach using a scenario within a live industrial project.

SIGSAND/PLAIS - Towards Agile Architecting: Proposing an Architectural Pathway Within an Industry 4.0 Project
Information Systems: Research Development Applications Education, 2019Co-Authors: Nuno Santos, Nuno Ferreira, Ricardo J. MachadoAbstract:Software Architecture design, when performed in context of agile software development (ASD), sometimes referred as “agile architecting”, promotes the emerging and incremental design of the architectural artifact, in a sense of avoiding “big design upfront” (BDUF). Performing “agile architecting” is not always straightforward, mainly because the Architecture has a required life-cycle and each stage responds to different needs. There is a lack of a pathway that guides agile architecting in an end-to-end approach (from business requirements to deployment). This paper proposes a pathway that includes Architecture design from software development life-cycle (SDLC) stages of software development that use ASD approaches, where two main artifacts are considered: a candidate Logical Architecture and a refined Logical Architecture. These artifacts are included in a pathway where they receive input from business processes perspective and guide software development during ASD iterations (Sprints).

modeling in agile software development decomposing use cases towards Logical Architecture design
Product Focused Software Process Improvement, 2018Co-Authors: Nuno Santos, Nuno Ferreira, Jaime Pereira, Ricardo J. MachadoAbstract:[Context and motivation] There are a plethora of agile practices that relate to management (e.g., Sprints, Scrum ceremonies), development (e.g., pair programming, TDD, BDD, DevOps) or strategy (e.g., Lean Startup), [Question/problem] but lack a comprehensive description on how its adoption influences requirements modeling and “You Aren’t Gonna Need It” (YAGNI) features. [Principal ideas/results] This paper presents Agile Modeling Process for Logical Architectures (AMPLA), an Agile Modeling (AM) oriented process composed by UML diagrams (namely, Sequence, Use Cases and Component). [Contributions] AMPLA uses agile practices in order to deliver small increments (of a requirements package) and to promote continuous customer feedback. The proposed AM process also includes a candidate Architecture and further requirements refinement in parallel with a software increment delivery.

an agile modeling oriented process for Logical Architecture design
BPMDS EMMSAD@CAiSE, 2018Co-Authors: Nuno Santos, Nuno Ferreira, Jaime Pereira, Francisco Morais, Julio Barros, Ricardo J. MachadoAbstract:Stakeholders are crucial participants for eliciting requirements towards a new software solution. However, agreeing a common understanding among them is a complex task in a project’s initial phase when solution requirements and design need to be refined and/or are unknown. In order to not delay the initial phase and thus endanger the entire project, this paper proposes a process to elicit functional requirements and to design a candidate Logical Architecture (i.e., without refining information), called Agile Modeling Process for Logical Architectures (AMPLA). By eliciting a set of “just-enough” UML Use Cases, i.e., that includes at least the core requirements information, it is proposed the use of a Logical Architecture derivation method, the Four-Step-Rule-Set (4SRS). This approach is suitable in agile software development contexts, where the solution’s Architecture is not known upfront.

the user model vocabulary and Logical Architecture for adaptive augmented reality
Latin American conference on Human-Computer Interaction, 2015Co-Authors: Maritzol Tenemaza, Angelica De Antonio, Jaime RamirezAbstract:Adaptive Augmented Reality (A2R) is an emerging technology that can support users in their daily life with useful information for their activities which is really adapted to the user's characteristics, to the environment where the activity is taking place, and to the current context. However, one of the problems identified is the lack of a formal definition of the models required and the Logical Architecture for the development of A2R systems. As a first step to this goal, our aim is to propose a detailed definition of the content of the User Model required for this type of systems. We explored state of the art ontologies for user modelling, and propose a set of significant user characteristics to be modelled. Also, we present an initial architectural model for this type of systems.
