Microservice architectures
MSA is an architectural style inspired by service-oriented computing
• Small services
• Running in own process
• Lightweight communication
Microservice architectures
3Di Francesco et al.
Paolo Di Francesco
MicroART Approach
• Problem: How to have a clear understanding of the overall
architecture?
• MicroART
1. Reverse Engineering
2. Model refinements
3. A Domain-specific language
MicroART Approach

5Di Francesco et al.
Paolo Di Francesco
Architecture Refinement
• Model refinements
• Produce an architectural model more significant to the
architect’s purposes (e.g., maintainability)
• Semi-automatic
• Iterative
Architecture Refinement
6Di Francesco et al.
Paolo Di Francesco
Architecture Refinement
• Service Discovery
• Services find each other dynamically in the network
• Loose coupling
• Mask “real” dependencies among services
Architecture Refinement
7Di Francesco et al.
Paolo Di Francesco
Architecture Refinement
Service Discovery Resolution
1. Remove Links
2. Remove the Service Discovery
3. Use log traces to identify new Links
