Abstract

The development and adoption of microservices, as one of the most promising directions for developing heterogeneous distributed software systems, have been driven by dynamic changes in business and technology. In addition to the development of new applications, a significant aspect of microservices is the migration from legacy monolithic systems to microservice architectures. Such development trends are accompanied by an increase in the number of primary and secondary publications addressing microservices, highlighting the need to systematize research at a higher level. The objective of this study is to comprehensively analyze secondary studies in the field of microservices from the following five aspects: (1) publishing trends, (2) quality trends of secondary studies, (3) research trends, (4) domains of implementation, and (5) future research directions. The study follows the guidelines for conducting a systematic literature review. The findings were derived from 44 secondary studies published in the period from January 2016 to January 2023. These studies were organized and analyzed to address the five proposed research questions pertaining to the study objectives. The findings suggest that the most promising research directions are related to the development, implementation, and validation of new approaches, methods, and tools that encompass all the phases of the life cycle. Additionally, these research directions have applications in a variety of business and human life domains. Recommendations for further literature reviews relate to improvement of quality assessment of selected studies, more detailed review of architecture quality attributes, inquiry of human factor issues, and certain maintenance and operation issues. From the methodological aspect, recommendations relate to using social science qualitative methods for more detailed analysis of selected studies, and inclusion of gray literature that will bring the real experience of experts from industry.

微服务的三次研究：研究趋势和建议

摘要

微服务的开发和采用作为开发异构分布式软件系统最有前途的方向之一，是由业务和技术的动态变化驱动的。除了新应用程序的开发之外，微服务的一个重要方面是从遗留单体系统到微服务架构的迁移。这种发展趋势伴随着涉及微服务的初级和二级出版物数量的增加，凸显了在更高层次上系统化研究的必要性。本研究的目的是从以下五个方面全面分析微服务领域的二次研究：（1）发表趋势，（2）二次研究质量趋势，（3）研究趋势，（4）实施领域， (5)未来的研究方向。该研究遵循进行系统文献综述的指南。研究结果来自 2016 年 1 月至 2023 年 1 月期间发表的 44 项二级研究。对这些研究进行组织和分析，以解决与研究目标相关的五个拟议研究问题。研究结果表明，最有前途的研究方向与涵盖生命周期所有阶段的新途径、方法和工具的开发、实施和验证有关。此外，这些研究方向在各种商业和人类生活领域都有应用。进一步文献综述的建议涉及改进所选研究的质量评估、更详细地审查架构质量属性、探究人为因素问题以及某些维护和操作问题。从方法论角度来看，建议使用社会科学定性方法对选定的研究进行更详细的分析，并纳入灰色文献，以带来行业专家的真实经验。
