Microservices Design Patterns in .NET - Second Edition
By :
This chapter explored various approaches to managing data in a microservices architecture. Unlike traditional monolithic applications that rely on a centralized database, microservices advocate for a decentralized model where each service manages its data. This architectural approach introduces challenges such as data integrity, inter-service communication, and transactions, which are addressed through different design strategies.
Different database management approaches exist, including database-per-service, shared databases, and event-driven data propagation. The database-per-service pattern allows each microservice to have its database, ensuring isolation and scalability. This model enables polyglot persistence, where each microservice can use the most appropriate database technology (SQL, NoSQL, Graph DBs, etc.). However, this approach increases complexity, costs, and maintenance efforts. Alternatives include shared database models, where multiple services share a...
