What is the optimal method for separating data and utilizing models among microservices in a Jira clone?

I’m developing a Jira-like application with separate microservices for users, tasks, and authentication. What is the best strategy to share data across these services while maintaining proper model separation and scalability in a production environment?

Based on my experience with distributed microservice projects, the practical approach is to let each microservice own its data entirely while communicating via asynchronous events. I found that trying to share detailed models or directly accessing each other’s databases caused synchronization issues and tight coupling. Instead, I implemented a publish-subscribe mechanism using a message broker to broadcast changes. Each service listens to the relevant events and updates its local state accordingly. This ensures that every service can scale independently and handle eventual consistency without risking immediate dependencies, which ultimately strengthens the system’s resilience.

The optimal strategy, in my experience, is to adopt a domain-driven approach where each microservice owns its own data and communicates changes via well-defined APIs and domain events. Using an API gateway along with message queues for asynchronous communication ensures that services remain decoupled. Relying on independent databases for each service and synchronizing through events maintains scalability and allows for eventual consistency. Integrating schema versioning and backward-compatible updates further reduces potential friction between services when business models evolve.

i’d stick with async events via a lightweight broker and local dbs, avoiding a shared schema; it keeps each service decoupled and scalable, though it might add complexity for eventual data synch. there’s always trade-offs, but it’s a flexible approach.

In my experience working with microservices architectures, I found that keeping data ownership strictly within each service while exposing only the necessary interfaces is key. I managed model separation by enforcing a contract between services without exposing internal models directly. Rather than trying to achieve immediate synchronization, I relied on an event-driven pattern where services broadcast changes and update their local state asynchronously. This approach not only minimizes coupling but also permits independent scalability and versioning. Additionally, I used centralized logging and monitoring to keep track of cross-service communications and troubleshoot integration issues.
