Which database is best for microservices?
For some services, a relational database is the best choice. Other services might need a NoSQL database such as MongoDB, which is good at storing complex, unstructured data, or Neo4J, which is designed to efficiently store and query graph data.
What is Microservice database?
A monolithic application interacts with a single database. The data is shared between all application’s components. By contrast, in a microservices app, data ownership is decentralized. Every service is autonomous and has its own private data store relevant to its functionality.

What is NoSQL database?
NoSQL databases store data in documents rather than relational tables. Accordingly, we classify them as “not only SQL” and subdivide them by a variety of flexible data models. Types of NoSQL databases include pure document databases, key-value stores, wide-column databases, and graph databases.
Why are there different databases in microservices?
Databases should be treated as private to each microservice.
This helps you to achieve consistency across different services. Event-Driven Architecture is a common pattern to maintain data consistency across different services.
Shared Databases provide a synchronized storage location accessible by multiple concurrent users. Two types of Shared Databases are available in Geneious. Your Geneious license will provide access to set up a standard Shared Database using Direct SQL Connection without additional costs.
What distributed logs?
Microservices and distributed systems are closely linked.So, the log messages generated by microservices are distributed across multiple hosts. As a developer or administrator, if you want to troubleshoot any issue, that leaves you clueless. You don’t know which microservice running on which host served your request.
What is polyglot storage?
