This article describes considerations for managing data in a microservices architecture. Because every microservice manages its own data, data integrity and data consistency are critical challenges.
A basic principle of microservices is that each service manages its own data. Two services should not share a data store. Instead, each service is responsible for its own private data store, which other services cannot access directly.
