Context:

Re-architecting monolithic systems with Microservices-based architecture is a common trend. Various companies are migrating to Microservices for different reasons. However, making such an important decision like re-architecting an entire system must be based on real facts and not only on gut feelings.

Objective:

The goal of this work is to propose an evidence-based decision support framework for companies that need to migrate to Microservices, based on the analysis of a set of characteristics and metrics they should collect before re-architecting their monolithic system.

Method:

We conducted a survey done in the form of interviews with professionals to derive the assessment framework based on Grounded Theory.

Results:

We identified a set consisting of information and metrics that companies can use to decide whether to migrate to Microservices or not. The proposed assessment framework, based on the aforementioned metrics, could be useful for companies if they need to migrate to Microservices and do not want to run the risk of failing to consider some important information.

从整体系统到微服务：评估框架

语境：

使用基于微服务的体系结构重新架构整体系统是一种普遍的趋势。出于不同的原因，各种公司正在迁移到微服务。但是，做出如此重要的决定（例如重新架构整个系统）必须基于真实事实，而不仅仅是基于直觉。

客观的：

这项工作的目的是为需要迁移到微服务的公司提供一个基于证据的决策支持框架，该分析基于对他们在重新架构其整体系统之前应收集的一组特征和指标的分析。

方法：

我们通过与专业人员的访谈形式进行了一项调查，以基于扎根理论得出评估框架。

结果：

我们确定了一套由信息和指标组成的集合，公司可以用来决定是否迁移到微服务。基于上述指标的拟议评估框架，对于需要迁移到微服务并且不想冒无法考虑某些重要信息的风险的公司而言，可能会很有用。
