基于自适应微服务的系统-前景和研究机会
Self-Adaptive Microservice-based Systems -- Landscape and Research Opportunities
摘要：
微服务在过去几年中变得流行，吸引了学术界和工业界的兴趣。尽管这种新的架构风格有很多好处，但它仍然带来了重要的挑战，例如弹性，性能和进化。自适应技术最近已被应用作为解决或减轻这些问题的替代方案。然而，由于影响微服务架构的质量属性的范围，可以使用许多不同的自适应策略。因此，为了了解在基于微服务的系统中使用自适应技术和机制的最新技术，这项工作进行了系统的映射，其中考虑到定性和定量的研究问题，对21项主要研究进行了分析。结果表明，大多数研究集中在自适应控制回路的监控阶段（28.57%），解决自愈属性（23.81%），在系统基础设施层（47.62%）应用反应式自适应策略（80.95%）和使用集中式方法（38.10%）。从这些研究中，有可能提出一些研究方向，以填补现有的空白。
英文摘要：
Microservices have become popular in the past few years, attracting the interest of both academia and industry. Despite of its benefits, this new architectural style still poses important challenges, such as resilience, performance and evolution. Self-adaptation techniques have been applied recently as an alternative to solve or mitigate those problems. However, due to the range of quality attributes that affect microservice architectures, many different self-adaptation strategies can be used. Thus, to understand the state-of-the-art of the use of self-adaptation techniques and mechanisms in microservice-based systems, this work conducted a systematic mapping, in which 21 primary studies were analyzed considering qualitative and quantitative research questions. The results show that most studies focus on the Monitor phase (28.57%) of the adaptation control loop, address the self-healing property (23.81%), apply a reactive adaptation strategy (80.95%) in the system infrastructure level (47.62%) and use a centralized approach (38.10%). From those, it was possible to propose some research directions to fill existing gaps.
