Validate Your Microservices
Service Lifecycle & Responsibility• Start of the service lifecycle• End of the service lifecycle
Business Events (incoming/outgoing)• Describe the events in a single sentence
Process description• Identification of major processes (non-
exhaustive)
Stakeholders• Roles of users of the service
