Does Each Microservice Really Need Its Own Database Microservice Design Pattern Interviewdot

рџђѕ Does Your Microservice Deserve Its Own Database By Leonid Belkind What is database per service pattern? the database per service pattern is a design principle in microservices architecture where each microservice is assigned its own exclusive database. this ensures that each service operates independently without relying on a central, shared database. It sounds simpler — one schema, one connection, less setup. but in practice, sharing a single database is one of the fastest ways to lose the main benefit of microservices: independence. let's explore why the “one database per service” rule exists and how it works in real systems.

Microservice Design Pattern Shared Database Vs Database Per Service There are a variety of patterns that are used for managing data within a microservices architecture. in this section, we’ll briefly introduce the essential ones. At its core, this principle means that each microservice should own and manage its own database no shared tables, no direct database access between services, and no tight data coupling. In the database per service pattern, each microservice has its own dedicated database. this allows each service to manage its own data independently, with different services. Microservices advocate design constraints where each service is developed, deployed and scaled independently. this philosophy is only possible if you have database per service.

Microservices advocate design constraints where each service is developed, deployed and scaled independently. this philosophy is only possible if you have database per service. The “database per microservice” pattern is a commonly used pattern with distributed microservices architecture, wherein each microservice manages its own dedicated database. this approach contrasts sharply with traditional monolithic architectures that rely on a single, shared database. In a complex distributed cloud application (example: amazon ecommerce), there are many microservices running. each of these microservices require storing data to a database. in a distributed application, data is stored across multiple machines (partition tolerant from cap theorem). The database per service pattern directly addresses this challenge by decreeing that each microservice should own and manage its own database. this pattern ensures that a microservice's data is private and accessible only through its api. Data sovereignty per microservice is one of the key points of microservices. each microservice must be the sole owner of its database, sharing it with no other. of course all instances of a microservice connect to the same high availability database.
