“…Some case studies report on Microservices migrations in a single company [12] or domain [4]. Balalaie et al extract common patterns from three industrial migration projects [13], while Di Francesco et al aimed to achieve more generalizable insights on migration activities and challenges by consulting 18 practitioners [14].…”

To remain competitive in a fast changing environment, many companies started to migrate their legacy applications towards a Microservices architecture. Such extensive migration processes require careful planning and consideration of implications and challenges likewise. In this regard, handson experiences from industry practice are still rare. To fill this gap in scientific literature, we contribute a qualitative study on intentions, strategies, and challenges in the context of migrations to Microservices. We investigated the migration process of 14 systems across different domains and sizes by conducting 16 indepth interviews with software professionals from 10 companies. We present a separate description of each case and summarize the most important findings. As primary migration drivers, maintainability and scalability were identified. Due to the high complexity of their legacy systems, most companies preferred a rewrite using current technologies over splitting up existing code bases. This was often caused by the absence of a suitable decomposition approach. As such, finding the right service cut was a major technical challenge, next to building the necessary expertise with new technologies. Organizational challenges were especially related to large, traditional companies that simultaneously established agile processes. Initiating a mindset change and ensuring smooth collaboration between teams were crucial for them. Future research on the evolution of software systems will in particular profit from the individual cases presented.

“…Ultimately, DevOps [2,13] and the microservices architectural style [14,15] with its domains of interests [21,22,23,24,25] may have the potential of changing how companies run their systems in the same way Agile has changed the way of In terms of pedagogical innovation, the authors of this paper have experimented for long with novel approaches under different forms [17]. However, DevOps represents a newer and significant challenge.…”

“…The container technology differs from traditional virtualization technologies in that services can be built in a shared host OS that only includes the applications and dependencies. Only the necessary processes need to run when services start, which means that the containers consume only the resources required for the services [38,39]. Once a container is built, it can be deployed and run without need for modification on any host OS.…”

The development, deployment, and maintenance of the current space situational awareness (SSA) information system have become increasingly complex. However, researchers cannot flexibly and conveniently apply the research results to practical applications due to the lack of basic research platforms for SSA. Inspired by X as a Service (XaaS), we propose the microservice-based platform for SSA data analytics to provide a scaffold-like platform for researchers. Based on microservice, the architecture for this platform is proposed to meet the requirements of flexible development and loosely coupled deployment. To facilitate the use of the platform, the hybrid data service layer is established to provide basic data for research and the functional service layer is designed to provide services for clients and applications. Due to the massive data processing requirements, the data analysis architecture and processing model, which can easily integrate various user-defined algorithms and significantly improve the computational efficiency, are proposed based on the Lambda architecture. To verify the platform's effectiveness, two cases are established and implemented. The results show that this platform can provide a convenient, flexible, and efficient platform for the requirements of algorithm integration, experiment, and data display from users and researchers.
