12. Transparency on responsibilities
• Easy information on members in charge
of Microservice
• Modern collaboration possibilities on
Microservice level
Why Microservices and EA?
• Complexity through high
granularity
• Challenging integration in
legacy software ecosystem
• Identifying spikes in over
network communication
between Microservices
• Providing agile teams easy
access to information about
Microservices (e.g.
responsibilities)
• Manage diverse
technologies
