Software systems play a fundamental role in modern everyday life, and cloud computing has significantly expanded their reach while simultaneously reducing complexities and costs associated with their development and deployment. In this context, software architecture emerges as an essential component to ensure an optimal structure according to needs, defining innovative styles such as microservices architectures, which consist of a group of small, highly specialized services. When considering the implementation of these systems in the cloud, the challenge arises of defining the appropriate cloud computing infrastructure, especially regarding the configuration of scalability properties, a task often characterized by its complexity and duration. To address this complexity, an extension of the Architecture Description Language (ADL) Sarch has been undertaken, allowing the definition of scalability properties. Additionally, model-to-model transformation rules have been established to facilitate the transition from an architecture model to an infrastructure-as-code schema, specifically configured to address the scalability quality attribute. This innovative approach aims to simplify the task of configuring the necessary infrastructure, accelerating and automating the process to enable a faster and more efficient implementation of advanced microservices architectures in the dynamic environment of cloud computing.
