The migration of legacy monolith systems toward a microservice architecture is a large-scale, nontrivial technical activity and investment. This shift would be infeasible without the use of robust underlying software that can sustain a big part of this work and sort the complexities involved. A myriad of Open Source Software (OSS) projects are available in the community for this purpose, however, many companies may remain reluctant to adopt them as the cornerstone for their new evolved systems that can work at scale. Ownership, security, quality concerns, or support confidence are widely common reasons. Furthermore, these concerns are intensified when the OSS is to take part in critical sections of the evolved system. Using a complex case study from Zalando, this article aims to give some light to both researchers and practitioners into the use of OSS to drive this evolution, and the impact that the OSS can have on the adopting system.

开源软件作为朝着分布式高性能平台发展的软件系统的主要驱动力：Zalando时尚商店案例研究

遗留的整体系统向微服务架构的迁移是一项大规模的，不重要的技术活动和投资。如果不使用可以支撑这项工作很大一部分并解决所涉及复杂性的强大底层软件，这种转变将是不可行的。为此目的，社区中提供了无数的开源软件（OSS）项目，但是，许多公司可能仍然不愿意将其用作可大规模运行的新系统的基石。所有权，安全性，质量问题或支持信心是普遍的原因。此外，当OSS参与已发展系统的关键部分时，这些担忧会加剧。使用Zalando的复杂案例研究，
