Enterprise-Level Migration to Micro Frontends in a Multi-Vendor Environment

Abstract

With new web applications rapid growth in size, the monolithic frontend approach has been increasingly challenged over the last years. The micro frontends concept has been proposed to match the architectural needs facing increasing complexity, e.g. for newly emerging cloud-native solutions. It provides function-level granularity and lets the developer adjust each process's performance. In the majority of relevant cases for which the micro frontends paradigm is considered, the system should be migrated, or an existing monolith should be converted to new technologies, whereas, the scientific community mainly focuses on greenfield designs. In this paper, we validate the paradigm, with a case study, in the context of migration for enterprise information systems, in a multivendor environment. Based on our analysis, we propose a method for the migration of frontend monoliths, along with guidelines and recommendations for future work.
