In a Microservice Architecture, ownership of service data can be handled in various ways depending on the specific needs and requirements of the system. Some common approaches are:
1. Centralized ownership: In this approach, a single service is responsible for the data and other services need to request access to the data through this service. This approach is simple to implement but can cause a bottleneck and create dependencies between services.
2. Distributed ownership: In this approach, each service owns its data and exposes APIs for other services to access it. This approach promotes autonomy and reduces dependencies between services but can be challenging to maintain consistency and coordination between services.
3. Hybrid ownership: In this approach, some services own the data while others use and share it. This approach offers the benefits of both centralized and distributed ownership and can be effective in balancing autonomy and coordination between services.
Ultimately, the choice of ownership approach will depend on factors such as the complexity of the system, the scalability requirements, the data consistency needs, and the overall system goals and objectives.
