Background: As software systems evolve and scale faster than the foundations on which they are structured on, software architecture migrations to modern, cutting edge paradigms of development are becoming common. An example of such a paradigm is Microservices-based Architectures (MSAs). With MSAs, organizations can manage the complexity of their software and deploy individual pieces autonomously and independently. However, migrating towards microservices entails a lot of complexity. The evolution of the structures that a migration predisposes is multifaceted, with a socio-technical nature.Objective: Therefore, this thesis aims to first of all understand the process in which decisions are made by engineers to migrate their software architecture towards microservices. In addition, this thesis targets to aggregate the migration journey of organizations that change their software architecture to microservices. Finally, it is demonstrated how an organization's operations implement different processes for software architecture migrations and development methodologies.Method: The methodologies used in this thesis are mainly qualitative methods. Grounded Theory and Grounded Theory-based analysis is used on interview data as well as textual data that engineers share in Q&A websites (i.e., StackOverflow). Moreover, a case study is also included to understand how engineers adopt certain agile practices and guidelines via observations, a survey and interviews.Results: The main findings of this thesis are regarding the comprehensive perspective on microservices migrations that take place in multiple dimensions (business, technical, organizational), in multiple levels of abstraction (architecture and system) and in multiple modes of change (technical and systemic migrations). In addition, 22 decisions and 53 solution outcomes are identified in detail. This work does not only approach migrations as a technical endeavor, but also as an endeavor with a strong social and business aspect to it, covering the basic elements of socio-technical systems as defined in literature. Furthermore, as the outcomes from analyzing microservices migrations resulted to processes and taxonomies, the thesis demonstrates a reflective view of developers percpectives in adopting processes and guidelines.Conclusion: Microservice migration projects entail an inherent complexity due to the different dimensions that the change takes place on, as well as the distributed nature of microservices. This work helps to decompose this complexity and carry a detailed understanding of microservices migrations to future attempts. Also, this work paves the way for studying further migrations to scalable cloud-based architectures and viewing them as comprehensively as possible.
