It means that we can use different database technologies for different microservices. So one service may use an SQL database and another one a NoSQL database. That’s feature allows using the most efficient database depending on the service requirements and functionality.
for instance, How spring boots develop microservices?

significantly, Which database is best for microservices?
It can, and there is certainly a place for that in many microservices architectures, but SQL is also implemented in at least two other types of databases that can be useful choices for many teams implementing microservices. The first is “small SQL,” which is the domain of open source databases like MySQL and Postgres.
also Does each Microservice need its own database?
The short answer is yes. In order to be able to independently develop microservices , they must be loosely coupled. … Each microservice’s persistent data must be private to that service and only accessible via it’s API .
Can microservices share same database? In the shared-database-per-service pattern, the same database is shared by several microservices. … This pattern does not reduce dependencies between development teams, and introduces runtime coupling because all microservices share the same database.

Is REST API a Microservice?
The terms RESTful API and Microservices go hand-in-hand when building a microservices-based application. Nevertheless, they refer to very different things. … RESTful APIs: The rules, routines, commands, and protocols – or the glue – that integrates the individual microservices, so they function as a single application.
Is spring boot and microservices same?
Microservices is the hot buzzword in software development and many organizations prefer building their enterprise applications using microservices architecture. In the Java community, Spring Boot is the most widely used framework for building both monoliths and microservices.
Why is spring boot preferred for microservices?
Spring Boot enables building production-ready applications quickly and provides non-functional features: Embedded servers which are easy to deploy with the containers. It helps in monitoring the multiples components. It helps in configuring the components externally.
What language are microservices written in?
Net microservices architecture allows a compilation of technologies between each service; as such, you can use . Net for a certain part of your app without implementing it everywhere. You can mix the . Net microservices with applications written in Java, Node JS, or any other languages.
Can we create microservices in .NET framework?
Build microservices with . NET. ASP.NET, the web framework for . NET, makes it easy to create the APIs that become your microservices.
Is MongoDB good for microservices?
MongoDB is well suited for a microservices architecture with its ability to provide a flexible schema, redundancy, automation, and scalability.
Why NoSQL is best for microservices?

Why microservice has its own database?
It would allow you to pick the database technology which fits your Business requirement best in order to get the best performance or usage of it. For example some specific micro-service might have some Read-heavy operations with very complex filter options and a full text search requirement.
How many microservices should you have?
New research from the University of Sledgham-on-the-World has revealed that the correct number of microservices for any software system is 489. Given that, why have so many organizations used a different number of microservices?
Can microservices call each other?
Another communication pattern we can leverage in a microservice architecture is message-based communication. Unlike HTTP communication, the services involved do not directly communicate with each other. Instead, the services push messages to a message broker that other services subscribe to.
Should microservices be RESTful?
Isolation or fault-tolerant is one of the most important goals when designing a Microservices. … Therefore, Microservices is more about architectural and design style, and you may be able to implement a Microservices without RESTful API. However, RESTful API makes it easy to build a loosely coupled Microservices.
Is microservice same as API?
Microservices are an architectural style for web applications, where the functionality is divided up across small web services. … whereas. APIs are the frameworks through which developers can interact with a web application.
Is Docker a microservice?

What is microservice REST API?
A microservice is a small, single service offered by a company. It derives from the distributed computing architecture that connects many small services, rather than having one large service. The microservice can then be delivered through an application programming interface (API).
