6th of April 2017. My presentation done at the 14th International Conference on Software Architecture (ICSA), Tool Papers, Gothenburg, Sweden. Microservice-based systems are characterised by a multitude of small services, each running in its own process and communicating with lightweight mechanisms. The microservice architectural style strongly encourages high decoupling among microservices in order to ease their independent deployment, operation, and maintenance. However, there are situations in which having a global overview of the system is fundamental. In this paper we present the first prototype of our Architecture Recovery Tool for microservice-based systems called MicroART. MicroART following Model-Driven Engineering principles, is able to generate models of the software architecture of a microservice-based system, that can be managed by software architects for multiple purposes.

Architecture Refinement
• Model refinements
• Produce an architectural model more significant to the
architect’s purposes (e.g., maintainability)
• Semi-automatic
• Iterative

Architecture Refinement
• Service Discovery
• Services find each other dynamically in the network
• Loose coupling
• Mask “real” dependencies among services
