   ABSTRACT     = {Microservices are deployable software artifacts that 
      combine a set of business features and expose them to other 
      microservices. Ideally, the reuse and interchanging of microservices 
      should be easy as they are supposed to be independent of each other, 
      both conceptually and technologically. Selecting a service to fulfill 
      a given feature (e.g., managing a cart in a website) recalls the way 
      Software Product Lines (SPL) allow variability. However, in practice, 
      interchanging microservices requires knowing the features that the 
      services propose, how they communicate with other services and their 
      types. In this work, we propose to analyze service dependencies as 
      feature dependencies, at the feature, structural, technological, and 
      versioning level, to assess the interchangeability of services. We 
      analyze six community-selected use-cases and report that services are 
      non-interchangeable systematically.}
