Abstract:

As the number of microservices increases, developer platforms are increasingly expected to support scalability by incorporating command line interfaces with standard delivery, observability and governance capabilities into the backend workflows of software development teams. In this review, we examine the microservice design patterns in the peer-reviewed journal literature that cover the topics of microservice architecture, DevOps, continuous delivery, cloud-native systems, migration, technical debt and developer productivity. The reviewed evidence suggests that effective platform design involves more than service decomposition; rather, it depends on the alignment between service boundaries, automated pipelines, interface contracts, operational feedback and governance mechanisms. As a result, CLI-centric access grows in importance but is not well studied because it can make it possible to translate platform capabilities into common developer workflows and to hide platform architecture. The studies reported reveal broad service granularity problems, fragmentation of developer tool chains, the burden of observability, migration debt, and the lack of an adequate empirical measurement of outcomes for developers working on platforms. With the aim of understanding how microservices and automation via CLI can be used to create scalable developer platforms without reducing platform engineering to a deployment-tooling-first practice, the article constructs a small conceptual model, makes comparisons and offers reproducible visualizations.
