Summary

Until now, we have seen several patterns surrounding microservices architecture and development. Each pattern’s purpose is to reduce the attrition that comes with this kind of architecture.

We saw a potential pain point and point of concern with our database-per-service pattern implementation and the difficulty that comes from having disparate data stores. We cannot always guarantee that all services will be successful in an operation and as such, we cannot guarantee that the data stores will reflect the same thing.

To address this, we look to the saga pattern, which can either be leveraged through an event-based choreography implementation or a more centralized orchestration method. We have reviewed the pros, cons, and considerations surrounding either implementation and how they help us to more effectively help microservices maintain data consistency.

In the next chapter, we will review the potential flaws involved in communication between microservices, and...
