Processes, Motivations, and Issues for Migrating to Microservices Architectures: An Empirical Investigation
MetadataShow full item record
Microservices have been getting more and more popular in recent years, and several companies are migrating monolithic applications to microservices. Microservices allow developers to independently develop and deploy services, and ease the adoption of agile processes. However, many companies are still hesitant to migrate because they consider microservice as a hype or because they are not aware of the migration process and the benefits and issues related to migration. For this purpose, we conducted a survey among experienced practitioners who already migrated their monoliths to microservices. In this paper, we identify a process framework based on the comparison of three different migration processes adopted by the interviewed practitioners, together with the common motivations and issues that commonly take place during migrations.
